i just purchased a 1999 yamaha warrior 350 four wheeler for some reason it keeps stalling some times its after 5min sometimes its after 20min of riding so if anyone can please answer this question i would really appreciate it thanks
Probably why the previous owner flogged it to you, he was having the same grief. Anyway next time the quad stalls, try loosening the fuel cap & see if it runs again, if it was used for off-roading then it could be that the breather hole in the cap is blocked. If that don't work then whip out the plug & see if your still getting a spark, could be a faulty ht coil or cdi which only start malfunctioning when the engine is warm. hope this helps....
