I'm new to this so I thought this wouldn't be bad, and it wasnt. The only problem was modifying parts and aligning the belt that wouldn't align properly with the parts given in the kit. Also the chain wouldn't fit without 2 masterlinks and the keys would fit into the jack shaft without the use of a hammer and wd40 Aside from these annoyances, it's a mighty piece of machinery that'll make your bike much more powerful. buy make sure you have metric with you for sockets.
This "kit" is misleading

This is just a 1002 kit. If you want the lug nut for the later models it is extra. The bad thing about it it's the wrong lug nut. Should be 1 to 1.37 long and this one is .75. Only maybe two threads engage. Your decals are on backorder and you will never get them.I contacted customer service and that was a joke. *********************ANSWER: Carl, Yes the 1002B for the Baja Minibike is the same as the 1002 with the same price. We offer the 1002B to make it easier for our customers to choose the correct Torque Converter. Yes, you can use the 1" Lug nut if you choose. the 3/4" works just fine. The Baja Engine is a very cheaply made engine. We recommend upgrading the engine. Please see our TrailMaster Monster Dog Minibike with several custom engine options, way better than Baja, Also, decals are in stock, we include them with every order. Thanks, Jeff

Thread: My Baja Heat 6.5 mods, baja heat mini bike parts
This is probably the easiest, cheapest thing I have done so far which I appreciate the most
My left foot in boots would always hit the jackshaft cover when riding over rough stuff knocking it loose which meant stopping completely to fix it
I simply drilled a small hole in each tab of the backing plate and used remote control car body pins to hold it in place
Total cost was like $0.25 and it really made a world of difference, can still pull the cover off easily but don't knock it off by accident
Damm! Now that's a good Idea I've already ran over and broke two covers on my baja when I didn't know they fell off.
Btw what car/truck do you have?
personally I'm a Traxxas fan boy and have a several of their vehicles

Here's what came in the box. I ordered it from GoKarts USA mainly because it was listed as being a direct bolt on fit to directly replace the cheesy jackshaft plate & tensioner that this minibike came with. Despite what is said on some of the forums around the internet, this is a good quality unit that is made right here in the good old U.S.A. Yeah sure it's got a couple of imported components in it, but suck it up sunshine that's just the way the world is, we're all on one rapidly shrinking planet and the market place is making it smaller everyday despite the best attempts by idiot politicians and knuckle dragging nationalists to stop it. Still it's nice to see something made here that is of good quality and is price competitive. The backing plate is especially well machined & finished to the point that it is almost a shame to cover it up with a belt guard.
Now this is not going to be a full complete step by step set of installation instructions, just an overview with a few tips. If have lost your kit instructions or have purchased a second hand unit without instructions please click here to get a set from the GTC websit e. As always you may click on any picture here for a larger view.
First you have to remove the original plate with the factory clutch & intermediate sprocket.
Make sure you remove all of the spacers from the end of the crankshaft, if you are doing this to an older engine oxidation may cause the spacer to look like an integral part of the crankshaft. If you don't remove it the drive pulley won't line up and you'll be scratching your head for a few minutes like I was.
This tab is no longer used and will have to be flattened or removed for the torque converter to fit.
The kit comes with longer bolts to mount the plate if needed.
This particular installation just reused the stock bolts
A picture of the driven shaft with the snap ring and washer installed.
Here it has been started through back of the mounting plate.
Next get the chain sprocket, key & spacer,
sprocket,spacer, & key
and slide them onto the driven shaft as shown here.
The next shot shows the driven pulley with it's associated hardware, slide it all into place and install the nut finger tight at this time.
Here is the driving pulley & the belt. When you cut the tie wrap to install it take not of how the various parts & pieces fit together so you can re-install them correctly.
I should have cleaned up the screw threads in this hole before I got this far, be sure to learn from my mistakes. BTW your engine must have an existing tapped hole in he end of the crankshaft or you cannot install a torque convertor. Be sure to check this before you spend your money as a few of the Honda clone engines are missing this feature.
The other drive pulley parts
Stick the belt into place & begin assembling the drive pulley onto the end of the crankshaft.
Now that you've gotten everything assembled it is time to tighten it all down.
You really need to use a torque wrench and tighten the bolts & nuts to the torque specified in the instructions. Even a cheap one is more than good enough for everything the average home mechanic will ever do. If you over tighten the nut on the driven shaft it will pop the snap ring loose from the other side. Sure GTC could redesign the shaft to eliminate the snap ring but are you prepared to pay an additional 20 or 30 dollars for the kit to cover the cost of the additional machining and wasted material? Just use a torque wrench and you won't have to worry about it.
I did this install several months ago and have been driving this thing around the farm at least two or three times a week. While it did not transform my otherwise nearly stock MB165 into a 50 mph speed demon it did bump the top speed up enough to be much faster than a stock Baja minibike. Perhaps on a smooth surface with the governor removed it would but it is already able to outrun it's own steering and stability out here in the deep soft sand & mud where I live.
Four months ago when I installed this it was purely out of curiosity to see if it would really be an improvement, and it really is. The initial low speed engagement is much smoother than with a factory clutch allowing it to be driven at a lower speed than was possible with the clutch, while still increasing the top speed. The belt has proven durable and still looks fine after four months of hauling my big 200+ pound ass around the farm, down the dirt road, through the woods. And when it does eventually wear out the belt is a little over half the price of a factory clutch. So is this worth spending the extra $200 buck on? If you are serious about actually riding your minibike, the answer is yes especially since the GTC TC2 is a direct bolt on that does not require engine mounting spacers to fit a stock Baja frame. Granted at this price it should come with the plastic belt guard but that really is my only complaint. At this time I'm running mine without the guard for a cool but possibly dangerous open primary look, but I don't let kids ride it either.
Here's a little video of the completed minibike so you can see how it works.

Standard Roller Chain
A chain consists of steel pins that are rubbing inside of "steel tubes". These are commonly called rollers, but it is obvious they do not roll. They just rub back and forth at very high speeds, under considerable load, pressure and heat. Squirting oil or even chain lube directly on these rollers does very little good unless the lubricant is given time to penetrate between each pin and the corresponding tube. The lube must go along the side links on each side of the chain, then allow 8 to 10 minutes for penetration and evaporation before starting the engine to ensure the centrifugal force will not sling it away. The clutch sprocket and the main drive sprocket should be perfectly aligned so they don't rub against the side links. Rubbing wears the teeth down rapidly and ABSORBS HORSEPOWER.
All chains stretch over time. When the chain starts falling off the sprocket then it's time to move the engine forward or backward to take up the slack in the stretched chain. There are four bolts that hold the engine on the motor mount plate. Take an open end wrench and a socket wrench, most likely a 9/16, and loosen the four bolts, pull back the engine until you take up the slop in the chain. Make sure both sprockets are perfectly aligned before you consider yourself done. You don't want the sprockets out of alignment because this will cause the chain to come off or wear the sprockets unevenly. Leave about 1/2 an inch of play between the top of the chain and the bottom, don't pull the engine back where the chain is as tight as you can get it. A tight chain can cause the kart to move in neutral with no one in the driver's seat. A tight chain also puts friction on the bushing, which could cause it to engage when the engine is idling. Make sure you properly retighten the motor mount bolts when the desired chain tension has been achieved.
Replace your chain when installing a new clutch or sprocket unless the chain is very new. If you are cutting a new chain make sure you don't cut it too short. You can always remove links but you can not add more than half a link.
If a replacement clutch or chain is required, determine the chain pitch size your machine is equipped with. Most American made fun karts and mini bikes use either #35, #40, #41 or #420 chain. Some chains have the chain pitch size stamped on the chain, some do not. Use the chart below as a guide.
Standard Roller Chain Specifications & Strengths
Many chains have the chain size stamped directly on the chain links
#35,40,41 & 420 chain are used on American Go Karts and Mini Bikes
An 11 or 12 tooth clutch sprocket usually indicates the use of #35 chain
10 tooth clutch sprockets usually indicate the use of #40, 41 or 420 chain
Make sure you order enough chain, any extra links can always be removed
Spark Plug Tips
Remove, inspect and adjust the spark plug according to the Engine Owner's Manual each time the oil is changed. The electrodes should be kept clean and free of carbon and excess oil which will greatly deter proper engine performance.
If possible, check the spark plug gap (the area between the electrodes) using a wire feeler guage. Should be .030".
Before installing the spark plug coat the threads lightly with a graphite grease or anti-sieze compound to ensure easy removal when the spark plug requires future inspection.
It is advisable to replace your spark plug at least once each year to ensure easy starting and optimum engine performance.
Engine Lubrication
You must change the oil in the crankcase after the first two hours of operating your new engine, and after each 25 hours of use thereafter. That will insure proper lubrication of internal parts and prevent costly repairs due to excessive wear.
WARNING: Disconnect the spark plug wire and place the wire where it can not make contact with the spark plug before changing the oil.
1) Remove the oil fill plug located on the rear side of the engine base. Tip the kart backwards slightly, by blocking up the front end and drain the oil into a suitable container.
2) Replace the oil fill plug and tighten securely. Place the machine back into a level position and refill the oil.
3) Check the oil level before each use. It only takes a few seconds.
Tip: An empty, plastic anti-freeze bottle can be used to make a great oil drain pan. Lay the bottle down on it's side. Cut out an opening large enough for the oil to drain into without making a mess. Save the cap and leave it in place until you are ready to pour the old oil into a proper container for disposal. The pan will have a handle and a funnel.
Storage Instructions
In the event your machine is not operated for periods in excess of 30 days and at the end of each season prepare for storage as follows:
1) Move the machine to an outdoor area.
2) Drain fuel tank and carburetor by allowing the engine to run out of fuel. All fuel remaining in the tank must be removed by using a suction device or by soaking up with a clean rag or towel.
3) Lubricate the engine cylinder by removing the spark plug and pouring one ounce of clean lubricating oil through the spark plug hole into the cylinder. Crank the engine slowly to spread the oil and replace the spark plug.
4) Do not save or store gasoline over the winter. Using old gasoline which has deteriorated from storage will cause hard starting and affect engine performance.
NEVER store gasoline in a building that has an open flame.
Centrifugal Clutch Tips
Driving Habits That Can Ruin A Clutch
1) Driving too slowly: A centrifugal clutch starts to engage around 2,000 rpm and will lock up around 2,600 rpm. Driving at speeds that allow the clutch to fully engage gives the clutch a chance to cool down. When the clutch is allowed to fully engage it locks the shoes in the clutch against the drum. When the clutch is not locked up, the shoes slip against the drum causing tremendous heat which dries up the lubrication in the oil impregnated bronze bushing. The tremendous amount of heat generated can also anneal the spring which is the heart of the clutch. If the shoes turn a blue-purple color from excessive heat, it's more than likely the clutch is ruined and the spring no longer has the ability to pull back the shoes at idle.
2) Short stop and go driving: The longer you drive at high throttle the better off it is for the clutch because it gives the clutch a chance to cool off before the next engagement. When the clutch is fully engaged there's no wear going on.
3) Driving with the foot on the brake: This is a problem with new drivers that are unsure of themselves. When riding a go kart for the first time, try to find an open area that has no obstacles that you have to maneuver around until you get use to the brake and gas pedals. The driver must first be able to build up his or her confidence on the kart before putting obstacles in their path. A small back yard is not a good place to learn to drive a go-kart. In my opinion, a minimum of � of an acre is the yard needed for a go kart. Teach your child to drive with one foot on the pedal be it the brake or the gas but not to press on both pedals at the same time. You either want to go or to stop but you cannot do them both at the same time.
4) Changing the size of the tires. Putting on tires that are larger than what came with the kart will result in clutch problems. Tires exceeding 13" in diameter stress out a clutch if the kart is not properly geared for the larger tires. If you are driving on smooth flat terrain than you may be able to get by with 14" tires but once you get on hilly terrain, deep grass, then you are putting additional strain on the clutch, which will cause premature wear. Big tires look cool on a go kart but you create your own problem changing to a bigger tire when the clutch isn't designed to handle them. If you have tires over 15" tall you are required to use a torque converter instead of a centrifugal clutch. Do not install rims larger than six inches if your go kart is equipped with a centrifugal clutch.
5) Weight: A centrifugal clutch is designed to be able to move a certain amount of weight. Once the weight limit is exceeded, then the life of the clutch will be shortened. A good rule of thumb is the kart and driver (and passenger when it is a two seat kart) should not exceed 400 pounds. The kart weighs around 150 pounds add to this the driver (and passenger weight, if it is a two seater kart). If you know ahead of time that you will exceed the 400 pounds then buy a torque converter go-kart and avoid the problems of burning up the clutch asking it to do more than it was designed for. A torque converter has a variable speed system between the driver and the driven pulleys so it can improve upon this ratio, which gives the torque converter an advantage over a straight clutch system. It improves the ratio by approximately 3:1 and can turn larger tires and drive at slower speeds without doing any damage to the clutch system. A torque converter is a more expensive system initially but it will last longer and is more trouble free when maintained.
6) Restrictions: Do not try and reduce a kart's speed by limiting the travel of the gas pedal or by putting a restrictor in the carburetor to limit full rpm. Either of these methods will result in the clutch slipping, which is self-destructive. A clutch needs full rpm to lock up as quickly as possible to be able to start to cool down. To slow down a go-kart you would need to purchase a gear reduction unit, which is like training wheels on a go-kart until the driver gets accustomed to how the go-kart handles. A gear reduction unit can reduce the speed of the go-kart in half.
How can I prolong the life of a centrifugal clutch?
1) Oil the bushing that is located in the sprocket at least every two (2) hours of driving time. Where do you oil it? Right where you see the snap ring on the sprocket at the end of the clutch. There is a bronze bushing behind the snap ring that needs lubrication. With the engine off, squirt several drops of oil while the bushing is warm. At the same time oil the chain. What oil should I use? A good automotive oil like 10w30 or a straight 30HD weight oil is good, use the same oil used inside the engine. Once the chain gets "kinky" from lack of oil it should be replaced before it does damage to the clutch sprocket. A new chain is cheaper than a new clutch. If you keep the clutch and chain lubricated you should get years out of both. Oiling the chain after it gets dried out is a waste of time. Remember it is preventive maintenance, which means before the items get ruined.
2) Don't put oil inside the clutch. The holes on the drum of the clutch are to let the hot air out of the clutch. DON'T SQUIRT OIL IN THESE HOLES. When oil gets in the drum portion of the clutch it will cause excessive slippage, which means undue heat will be generated.
3) The oils that can give you problems if they happen to get on your brake disc or in the drum of your clutch are: Slick 50, Dynamite, or Energy Release. These are excellent internal engine oils but will give you "fits" if they get inside the clutch or on the brake disc. They do just what they are intended to do which is to prevent friction -- steel to steel contact. On a clutch you need friction to have it engage and the same goes for a brake system. Because the oil comes out in very minute amounts and gets on the inside of the clutch drum. The clutch would only slip, it would not and could not lock up. This oil will impregnate the steel. Sanding and cleaning with a solvent or gas will not help. Once it is in the metal, it is in there forever because the heat will bring these lubricants back to the surface.
4) If your kart has a grease fitting in the crankshaft for lubrication then a shot of grease twice a month should be sufficient lubrication. The grease is coming from the inside of the sprocket outward, which is a better way to lubricate the clutch. The keyway in the crankshaft acts as a reservoir for the grease, which cuts down on the frequency needed for maintenance compared to oiling the snap ring area. The chain still needs to be oiled frequently to keep it from kinking up. There are some excellent chain sprays available that are waxy and will not let sand and dirt adhere to them. Dirt and sand will wear the chain as well as the sprockets.
If your go kart takes off by itself when the engine is started, with no one in the drivers seat, that is an indication that the clutch is badly in need of lubrication. Turn the engine off and park the machine up against a tree or fence to prevent it from taking off when you crank the engine again. You can also put the rear end up on centerblocks so the rear wheels are not touching the ground. Lubricate as needed. Give the lube enough time to penetrate, then start the engine. If the machine continues to take off by itself even after the clutch has been oiled, the clutch is burned up and must be replaced.
How long will the clutch last? If put on the crankshaft properly and observing all the hints that are pointed out in this article, a clutch should last many years. But if it is improperly installed, driven in abusive conditions (lack of oil, sand, steep terrain, excessive weight in the kart, wheels that are to tall), the clutch might only last 20 minutes.
Teach your child how to do maintenance on the kart or mini bike and accept responsibility for its upkeep. Every second tank of gas in the kart is about the interval for oiling the chain and the bushing. Oil the clutch even more often if an unexperienced driver is riding the machine around slow without gaining enough speed to engage the clutch all the way. If your child learns to do this preventive maintenance your machine should be enjoyable for many years. Who knows, if the kart is taken care of you may one day watch your children's children ride the machine, Priceless.
Tips To Remove Clutches
How do I remove my old clutch? I've tried everything!
Always make sure all the pieces of the old clutch are removed from the crankshaft before attempting to install a new clutch. It's not uncommon to think all of the old clutch has been removed when it hasn't.
If your crankshaft is rusty, clean the end of the crankshaft with a wire brush. You should be able to see the end of the keyway cut into the crankshaft. Dig as much rust as you can out of the keyway and spray some penetrating oil between the clutch hub and the crankshaft. There are often one or two set screws in the clutch hub, near the engine and perpendicular to the crankshaft, which bind the hub to the shaft. Remove them if they are present. If your clutch is in pieces coming off and being difficult to remove completely, disassemble all the pieces from the clutch hub. Once all the other pieces have been removed you should beable to get a grip on the clutch hub with a gear puller and pull it off (don't forget to use penetrating oil). Be sure to put a bolt in the end of the crank to protect the threads inside. If you don't have one, you can rent a gear puller from an auto-parts store for around $10.00 to $20.00 a day.
If a gear puller won't work you will have the cut the clutch hub off without damaging the crankshaft or oil seal. A cutting torch will most certainly burn your oil seal, so replace the oil seal if you use heat. A high-speed die-grinder with a thin abrasive disk cutting wheel is one possible tool to use in this situation. We score a deep gouge in the thick part of the clutch hub, parallel to the crankshaft, being careful not to cut all the way to the crank. Then use a blunt chisel and a hammer to break the clutch hub along the score line. This loosens the hub enough that it comes off easily with a puller.
Brake Systems
Brake Rod Adjustment
1) The brake rod should be adjusted (effectively shortened) if the brake pad doesn't press hard enough to stop the kart.
2) To adjust the brake, shorten the brake rod by removing the fastener through its forward end, then reassemble the connection by using the next hole toward the rear.
WARNING - Do not overtighten the fasteners, the pedal must be able to move freely.
3) Additional adjustment can be made in a similar manner to vehicles equipped with a scrub brake system ("brake paddles" that rub your back wheels to a stop), which can also be adjusted at the rear of the brake rod where it attaches to the brake lever.
WARNING - Ensure proper fasteners in good condition are installed throughout the brake system. Failure of these fasteners may cause brakes to fail.
