Ok, stock 48cc Grubee, installed and tuned right.
Came with original bike chain, worked fine.
Bought a 415 ahttp://motorbicycling.com/newthread.php?do=newthread&f=39nd measured it right, installed it with a spring-loaded chain tensioner.
The chain simply won't wrap through the sprocket smoothly.
It hangs up on the tight circumference of the stock sprocket and gets stuck at every revolution.
What's up? Any comments?
