my bike is a schwinn jaguar 26" frame set up with 24" wheels and tires a 79cc with heaver valve springs , a split ring karting sprocket with an aluminium adapter I made ,I am using a #35 chain from gokart the chain hasn't failed me yet ,been running it for the past 3.5 years but like all things you build you MUST do your maintanence or else you should just not get involved in this fun hobby
