RIght side smoking??

Post by SIDECAR77 » Mon Aug 17, 2009 7:56 pm

Finally got my superhawk running just right, and now the the right exhaust started smoking but not the left suspect vavle to be the problem or ring, smoke is gray going to try adjusting vavles and see what happens. Is it possible to have only one ring worn and not the other

Is it possible to have only one ring worn and not the other[i have a similar problem smokes when cold but the smoking stops when when hot i think it might be that the valves getting worn and drop when cold letting the oil thats in the head drip into the cylinder i'm going to strip it down soon and check this out if you have any ideas let me know and if i find anything out i will pass it on/quote]

I have stripped the engine down valve guides are perfect and the piston rings are the same . The only thing i found to be wrong is the pipe that run's form the inlet valves ( out side the head join's the valves) was blocked on the side that was smoking . When i have got it back together i will let you know if it has made any difference .

Pete, as Honda eliminated those vents later in production, I think your problem lies elswhere! Are you installing new rings? The machine shop by me can machine the top of the guides, and install oil seals. It sounds to me like your issue was due to valve guides.

Pete

Have you had a look at the head gasket? If everything else really is hunky-dory, I wonder if you have a substandard gasket or o-rings around the oil feed. I would vote for valve guides but it might be something else letting extra oil into the exhaust.
