This kit replaces the light duty #35 chain with the #420 heavy duty chain making it less likely that the chain will fly off of the sprockets.
You will need the 5/8 clutch if you still run the 79cc engine and we recommend using the 60 tooth sprocket. if you have changed the engine to a clone or 212 use the 3/4 clutch and you will have enough power to run any of the sprockets.
- 6 Hole 420 Sprocket
- 10 Tooth Clutch with key and 2 set screws
- 5 Feet of 420 Chain
- 1 Master Link
- Doodle Bug

Concern: if I buy the sprocket by itself, the description says it’s made of steel. If it’s bought as a package, it’s aluminum. I wanted steel for durability. If you truly have a 6-hole in steel, I want that option to purchase in the package.
I own a mm105cc and did moto swap for a predator 212cc after watching cars and cameras, RBG and Kartfab . This guys were every helpful in helping me understand what was the best parts and tips for swapping motors . The parts are very strong and durable the shipping was fast !! Iordered in the parts afternoon on Tuesday it was at my house Friday and the mini bike was running Saturday afternoon . I’ll be shopping again from go power sports .
