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

What an amazing product. Perfect for my Ct200uex (with a riser). I feel like most of the bad reviews are folks the installed it incorrectly. All the fasteners are left loose so you can swap the sprocket for a #35 chain, so check everything before your first ride. I'm really happy it came with American fasteners for predator engines. I literally bolted it together and it works perfectly even after several hours of mobbing the neighborhood. The belt seems to be mid, as after a few hours its looser and noticeably wearing. I ordered some 5959 belts because Google AI said they're interchangeable and the 5959 belt is more durable. So I recommend ordering some spare belts. You will need a riser plate if you're putting this in a minibike. My 224 predator minibike is pulling wheelies off the line and went from 36 to 49 phone tops speed. The clutch on the engine is noisy, that's probably my only real complaint. It's kinda "clacky" at idle, where as the super 30 "juggernaut" is quiet. But still for the money 10/10 recommend

Awesome product. I have purchased several of these for my mini bike builds.

Works great on my mini bike project. Not sure if top speed was affected but definitely gained a ton of torque. Only problem is that the belt lasted maybe 2 days before exploding. The plastic cover worked amazing and blocked everything, preventing a possible injury.

The packaging was very secure when I received the product. Upon opening it, I could see the workmanship was exquisite, with even welds and meticulous attention to detail, giving it a very solid feel. The installation technician also praised its quality and craftsmanship. The installation process went smoothly, without any issues like incorrect dimensions or unusual noises. After installation, I took it for a test drive. Gear shifts were incredibly smooth, with almost no jerking, acceleration was more linear, and the throttle response was significantly improved. Previously, I always felt a bit sluggish at low speeds, but now there's no slippage at all. After driving for a while, I noticed a slight decrease in fuel consumption, and the overall driving experience has improved dramatically.

I recently installed the 212CC 6.5 HP torque converter kit on my Predator 212 minibike, and after a few weeks of testing, I’m impressed — it’s one of the best performance upgrades I’ve made for under $100. ⸻ First Impressions & Build Quality Straight out of the box, the kit looked well-machined and thoughtfully packaged. All the components — the driver pulley, driven pulley, belt, spacers, and bolts — came clean and smooth, with no obvious casting flashes, burrs, or defect edges. The aluminum surfaces have consistent finishes, and the pulleys spin freely without noticeable wobble. Everything was clearly labeled, and the parts matched the spec sheet provided. One thing I appreciated: the pulleys are anodized, which seems to protect them from corrosion and minor scratches. Even after a few ride tests, the surfaces are still bright and sharp. ⸻ Installation & Fitting I set aside an afternoon to install it, expecting a fair amount of custom work. Fortunately, the kit is mostly plug-and-play with only minor tweaks needed. • Backplate alignment: The backplate’s holes lined up almost perfectly with my stock engine block, needing only small adjustments, not full re-drilling. • Shimming and spacing: I used a feeler gauge to check runout and shim clearance. A few thin washers got the driver parallel to the crank and avoided belt rubbing. • Torque and securement: I used blue Loctite on the main shaft bolt and torqued it to spec. Everything held tight. • Belt path & guard clearance: I checked the path carefully and trimmed a bit off the inside lip of my engine cover so the belt wouldn’t rub. • Break-in: I ran the engine gently for the first 10 minutes, keeping throttle light, to let everything seat before doing full-throttle runs. By the time I was done, I felt confident in the mounting and clearance. No weird noises or binding. ⸻ Performance & Behavior Once I hit the throttle, the difference was obvious: • Smoother engagement: The torque converter transitions more gradually than a clutch — no sudden shocks or jolts. Launches feel more controlled. • Wider usable powerband: The engine feels more flexible at low RPM, with less bogging in tight turns or steep terrain. • Climb and load: On uphill sections with a passenger, the belt stayed solid without slipping. Even heavy load didn’t push it past its limits in normal terrain. • Top end behavior: At full throttle, the unit seems to shift out close to where I expect it to, giving a strong top-end feel without being overly aggressive. • Heat & longevity: After 30+ minutes of continuous riding, the pulleys were warm but not hot, and the belt didn’t smell burnt. Checked it afterwards and saw minimal wear — no glazing or edge cracking. Over multiple sessions, performance stayed consistent. No drift in belt alignment or slop in the pulleys. ⸻ Strengths, Weaknesses & Suggestions Strengths • Great value for what you get — drivers, driven, belt, hardware all included • Smooth, user-friendly operation with noticeable gains in low-end torque • Durable finish and minimal wear after regular use • Flexible enough for riders with intermediate mechanical skill (tweaking, shimming, etc.) Weaknesses / Watch-Outs • Some small adjustments might be needed (backplate alignment, cover clearances) • Belt tension and path must be precise — misalignment causes premature wear • Hardware quality is good, but I replaced a few bolts with stronger grade from my spare stash • Not a plug-and-play upgrade for absolute beginners; some mechanical knowledge helps Suggestions for best results 1. Use blue or red Loctite on all critical bolts. 2. Double-check belt alignment under load before final torqueing. 3. After first use, re-inspect alignment and tighten again as needed. 4. Keep spare belt and hardware in your tool kit — it gives peace of mind on long rides. ⸻ Final Verdict This 212CC 6.5 HP torque converter is an excellent upgrade for anyone wanting smoother acceleration, better hill-climbing, and more usable power in a small engine setup. While it’s not completely drop-in flawless (you’ll want to double-check alignment and make minor clearances), the results are well worth the effort. In value, performance, and durability, I’m giving this kit a 5-star rating, especially for intermediate DIY mechanics.

Exelente compra

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.

Great kit with everything included. Had to get an engine riser plate for my 212cc mini bike or else it will with the frame. Haven’t ridden mini bike with it on but I’m sure it’ll be better then the old clutch setup. Also had to add more chain. Was a direct fit and install went smoothly, other reviews said clutch bolt would come loose so I ended up using red loctite just in case

Perfecto!!!!!

This thing made my bt200x an absolute monster, the bike has a governor delete, heavier springs, a flywheel, a carb and an exhaust. It does 70, I would not recommend for a stock bike as it needs the higher rpms for it to really go fast. But if you plan to do a mild build like mine then I totally recommend, the only thing is the stock belt is bad and will get shredded in one or two rides. A good quality belt is only an extra 10 bucks or so, I think it's worth it and it's made the bike so much more fun to drive and I can explore places further away!
