Yamaha Moto 4 250 Won't Start - Help Appreciated in Yamaha ATV Forum Posted July 20, 2018 If it’s smoking that bad, it’s probably a ring or valve seal. Check your oil immediately after shutting it off. If you have smoke coming from your crankcase..... scratch everything else, you’ve got a blown head gasket.
