I bought a ktm50 clone from thatsdax and the engine sprocket uses 420 chains. Is it possible to use the 420 chain with the china girl kit sprocket? I actually have the Manic Mechanic adapter and 44 tooth sprocket and wanted to use the 420 chain.

Go ahead it will work. You might want bigger sprocket the power band in those engines is in high RPM. Are you going to bring it to the races?

I am still thinking of increasing the Sprocket to 46-48 teeth as I saw Wild-Bills youtube video of his ktm50 and he recommended that. I have never raced and was not planning too but I wouldn't mind giving it a go. I saw a post the next race in Apple Valley is Oct 22nd. I would go but the problem is I'm not sure I would finish mounting my engine by then. Everything is ready I just need a welder to create mounts just like Bill's. I already bought all the parts and the mounts Bill uses but I do not know how to weld I'm searching for someone in the inland empire.
