IPARTS EXPERTNew 30 Series 6.5 HP Go Kart/Mini Bike Torque Converter Clutch Driver Pulley Replacement Comet Manco 212CC 3/4" Bore Max Torque 3/4" Torque Converter Clutch 219552A

If you are considering a torque converter upgrade on your Coleman mini bike, this will give it a real kick in the pants. There are some considerations however. If you have the 212cc engine... all systems go. If you have the 196cc engine... contact Houston... there is a problem. The shaft size on the 196cc is 16mm. That's not 5/8", so a 5/8" - 3/4" adapter won't work. (don't believe the U-Tube videos) You can get a 16mm to 1" adapter (16mm To 1" Crank Adapter Sleeve Coleman Ct200u/-Ex Bt200x CAS) from OMB Warehouse, E-Bay. That also means you need to order the torque converter with a 1" driver. The price is a little over $100.00 with shipping and exchange. The route I chose however was to replace the engine with a 212cc from Princess Auto for about $165.00. That gives you another hp over the 196cc and a few more revs too. You have to use the light kit from the 196cc, but that is an easy swap. You also need to swap the muffler and throttle linkage. (note: I saw the 196cc has a throttle stop, so I removed that!) You also have to add a short piece of 420 chain which you can scavenge off of the front chain. I am selling the 196cc c/w clutch and intermediate jackshaft for a $100.00 to get some return and reduce costs, so it is actually the cheaper option. It's a pretty straight forward refit. I weigh about 210 lbs and it really improved the takeoff as well as the top end. The only problem with the extra speed is now you should consider some serious braking... Go Power Sports has a front brake mod, but it's fairly expensive. ($$$ verse serious injuries...?) Take your time and enjoy the process as well as the final product. It's all fun! PS Use the riser plate sold on Amazon too... looks factory and is so much easier than a Mickey Mouse pile of washers or something.

Simple to install and works great so far. Seems to have more torque and higher speed than it's replacement. Durable so far haven't had any issues driving 20mph for several hours. I did need some additional shaft shims as others have mentioned, but I think that speaks more to the variety of machines this can be used on and getting proper alignment.

Hay que cortar la tapa de plástico para que pase la cadena , así como el tapón de aceite del.motor porque topa con la tapa del cvt .

fast shipping and much better quality than some other from this site that i have purchased..thnx guys!!!

Installs smooth and works well
