[QUOTE="kirrbby, post: 170608, member: 3972"] Another short, cold ride today. No change. Motor smoked badly, and started smoking very quickly after startup. Didn't clear up much at all while it warmed up. It made me think that oil may have seeped into the combustion chamber after I shut the engine off last time. I now have the cylinder studs torqued to about 11.5 foot pounds :-! Rode it for about 10 minutes. Clutch slips, and I can MAKE it slip if I try. After my ride, the smoke had cleared up quite a bit again. I let it sit and idle for a while to see if it would start smoking worse, at low rpm's...no change tho. I ordered new fibers for the clutch today...Vesrah, from dratv...hope those are good. I also ordered some new, taller, cap nuts for the cylinder studs...thinkin maybe the short ones I have may be bottoming out on the studs..? I'm runnin out of cures for my smoking problem...maybe the rings? Maybe a misplaced rubber oil seal in the head gasket?..twice? Maybe a crack, or other defect in the head casting?? I should have probably bought a set of new piston rings too...for 25 xtra beans...start fresh with the rings. IDK...when I pull the top end AGAIN, I'll be looking at every single thing that I suspect COULD possibly be causing my smoke issue, VERY closely. Any ideas?? I'll be pulling the engine out of the bike. Look for a problem that's allowing oil to be sucked or pumped into the combustion chamber. New discs in the clutch. 2 new heavy duty springs in the clutch. I'm gonna cut 1mm off of the shank of my homemade clutch pusher. Pull the rings off and check the ring gaps. Hone the cylinder and put everything back together with new cap nuts on the studs. I'll make ABSOLUTELY sure, that the round rubber seals are correct in the head gasket. Address the leaky kicker seal. [/QUOTE]
