That 92153D bolt illustrated looks like it might be a "shoulder bolt" where the unthreaded part is larger than the threads. They are used where they don't want the bolt to clamp two parts together and for the bolt to act as an "Axle" for levers or other rotating parts. Some industrial supply stores may carry what you want but your best bet might be to order them through an ATV dealer.
The clutch lever you might as well take it off and go to a hardware store to see what works. The same for your axle carrier. If the hardware store doesn’t. Try Home Depot. Sent from my iPhone using Tapatalk
start with a new fully charged battery. some times after running a battery gets a surface charge but dies quickly. do some quick voltage tests and let us know what you find.
12.8-13.2v fully charged battery
no less than 11.5v when cranking
should climb above 13v when running above idle
