Thanks that's good to know. I must say that I'm dead impressed with the zoombike kit, it came with a load of stuff I was not expecting.

Its a tool used to remove the small drive sprocket on the left side of your engine. You'll probably never need it.

and it removes the clutch and small gear on the other side....you hope you never have to use it
