So when u say using the clutch to bring the piston heads up do I have to look at them and make sure there at dead top? First time doing this and I put the head gasket on with out bringing the pistons up to top. Or can I just turn the clutch and it will bring it up it’s self

@@montemania198210 I just picked up a sportsman 800 with only 115 hrs on it and it just started smoking. Is this likely to be a reoccurring issue on these twin 800’s?

[@montemania198210]

@@danielhaskins519 I usually see this happen from dirt and mud ingestion on these machine. Mainly cause people push these 800’s hard lol.

[@danielhaskins519]

@@montemania198210 I’d like to think that was the case. But it was owned by an old man and he had daughters that would ride it. He was the original owner. Granted I did still find a little mud here and there. The previous owner also told me the quad seems to foul plugs fairly quickly. Can lack of maintenance contribute to pre mature ring failure?

[@montemania198210]

@@danielhaskins519 absolutely it can. Also if it’s burning oil will 100% foul plugs out.
