I have a 98 wolverine 350. After i ride for 15 min it loses alot of power. Will barely turn the tires. Ive checked compression and checked valves. I sprayed the engine with a water while it was hot and it got the power back until it got hot again. Maybe electrical im thinking? Any ideas would help. Thanks

 

Having the same problem with my 99 and havent found anything yet. I will let you know as soon as i do or please let me know
