212CC Torque Converter 6.5 HP 3/4" Go Kart Mini Bike Comet Clutch 10T 40/41 and 12T 35 Chain Predator Driver Pulley Replacement Set - 30 Series

Works great with my Stretched doodle bug 30 frame.(Just make sure to first oil the brass bushing or it WIL seize up!!)i have an adapter plate that allows you to move the engine back and forth; left and right. i did have to cut off a part of the backing plate to make it fit correctly. paired up with a 40 tooth sprocket and 12 tooth output sprocket, #35. my predator 212 has springs, A billet rod and flywheel, and a vm22 carburetor and i’m able to hit 42mph with the Torque Convertor. i’m upgrading the camshaft soon so i am expecting to hit about 55 mph

Bought 2. One for b200r and one for a harbor freight 212 motovox project. 20+ hours or ride time on both with no issues

I bought this kit for a Massimo mb200 (warrior). To start, the instructions are limited and only give you the very bare bones in how to assemble everything. If you have some mechanical aptitude, the instructions a pretty self explanatory. It will fit the Massimo, BUT you will need to modify it. There are several ways to make it fit, just look up some videos, but we went a slightly different route and shifted the whole engine over about 3/4”. That was enough to get us clearance for the backplate and to get us lined up with the chain sprockets. The only modification I did to the backplate was grind down one of the raised sections that was tapped for a screw to the cover. We have 3 out of the 4 bolts holding it on and it hasn’t been an issue. We also had to use a washer or two to bring the backplate off the block for sprocket alignment. Also, others have stated this, but the drive shaft is not tapped, so the included bolts will not work in this kit. You need a deep-well lugnut and a washer to attach everything to the driveshaft. You also need to grind down part of the key that attaches to the driveshaft, another thing others have ran into. As long as you have clearance and everything lines up, this it a HUGE improvement over the stock centrifugal clutch! Just take your time. It will take about 2-4 hours to do the modifications and install. The only reason I didn’t give it five stars was because of all the modifications and the fact that it came with the wrong belt. It came with a 669 belt, but it really needs a 5959. The belt that came with my kit was too small and it made the bike walk away at idle and very difficult to move when it was shut off. Overall great kit, quieter than stock clutch, looks great, and goes faster. It just needs some TLC to make it work on a massimo. When you buy this kit, by a 5959 belt and lugnuts, and you will be all set!

I purchased it to help my mini bike go through dirt roads and hills since my clutch couldn't do it and this works really good I'm able to keep my speed while going up hills which is amazing. Installation was super easy but you will need an engine mount riser to fit the torque converter

This torque converter is made of high-quality materials and precision machining to ensure its durability and reliability. It can effectively transfer engine power to the wheels, providing strong acceleration and stable driving speed. Moreover, its installation process is relatively simple, following the steps in the manual, it is installed in no time!

The driver hub that attaches to the output shaft is horribly made - the key machined into the hub isn't on center and the bottom of the key got hacked off which would prevent full engagement of the key into the output shaft. I work in a machine shop and even I don't want to spend the time or resources to fix this garbage. No way to contact the seller either so don't waste your time with this one. I can't imagine you'd get a driver hub any better than I got.

I bought this for my Coleman b200r Becuase I wanted more power and I didn’t want to take the governor off. so you need a engine riser for it so it fits and I also had to cut the chain so it fits and you need to cut the chain cover so it fits the chain lol. Since you need an engine riser you also need a new exhaust I fit that too. The tourqe converter is CRAZY I was doing small power wheelies and my top speed was about 33mph and the governor was still on the engine so this thing is insane I would definitely buy this

Did not function as received. The belt was so tight that it locked up the converter. I had to make a thin round shim to get the clutch to release. Now it is running. Not sure but it appears that the belt MAY be just a little wide.
