I bought this atv a couple of months ago for pretty cheap looking to make a project out of it. It ran at the time but smoked horribly. So I tore it apart and found the rings were smashed stuck, piston scratched on 4 corners along with the cylinder. It was already bored out to the max so I bought a new cylinder piston rings and also decided to replace the crankshaft due to some questionable play. I figured the smoke was due to the worn piston and rings… fast forward a month after getting parts a few times, I put it back together and the POS still smokes just as bad as it did the first day I brought it home!

(I forgot to mention I did replace the valve seals)

Honda ATV Forums please help! The problems I’ve had while rebuilding this are unreal. From tearing into it I know the previous mechanic was a complete moron so anything is possible. What could cause it to still be smoking/burning through all the oil in the reservoir in a matter of minutes? Could it have something to do with the oil pump? Possibly not working..
