Strangely enough I wasn't able to find much on this problem using search function...
So I've been getting my bike tuned and working on ironing out a few wrinkles.
I got it running decently and have been cruising around; the other day I rode about 5 miles, stopped, then rode another 2-3. When I parked I noticed the breather was puffing white smoke/ as the bike was idling....it was almost vapor like
I have another thread regarding my carb tuning woes. I'm fairly certain I have a few leaky valve seals. But when I stopped I noticed the white smoke puffin out the breather at a steady rate. Killed the motor and checked the oil and it wasn't smoking like it was at the breather. The motor wasn't very hot. I let it cool down and then got it back home. It started and drove fine.
I drained the oil and there wasn't fuel in it and it was at capacity, pulled the plugs and they're black, so indicating lean or preignition, and I peered into the cylinders to see healthy piston tops, albeit a bit of oil. I've only out about 30 miles on the bike since I finished the rebuild.
When I got the sidescreen off there was an accumulation of grit that felt like clutch material (bike has new new clutch discs). I haven't pulled the sump yet. I've been advised that my culprit is most likely the headgasket pulling oil from the cam chain tunnel, but what other reason could there be for smoke to be coming out of the breather at temp? Blow by?
I should mention that it seems more like vapor than smoke.....after I got it home I looked at the breather and it's almost like it was misting raw fuel....smelled like exhaust. But it's definitly not putting out any oil.
EDIT: I've read on a few Honda forums that this could simply be water vapor.....any thoughts? Was hoping to ride out the season before I do any head/piston work.
