I would reshim the exhaust, when the bike warms up they get tighter

I agree with MegaDeth. Loosen up those exhaust valves. I will admit that I thought they'd be tighter than that though with the symptoms you had. .18 isn't real bad, but with both being tight, it might be just tight enough to keep from firing up reliably. Heck, if it was me, I'd even loosen up those Intakes! Two of them are right on the minumum as is. And since you have to shim the exhausts anyhow, I'd do all of them and be done with it for quite awhile! Maniac

Intakes snug too!
