It probably you set valves on wrong stroke
 There are two TDC positions for each cylinder, one on TDCC (compression) one on TDC overlap.
 Re-check clearances first.
 Watch intake valve, as its coming up, your getting close to compression

You didn't use metric spec with inch feelers?
 You did curve/bend feelers to fit under adjuster?
 Did you check intakes with 0.003" 'no go' after setting to 0.002"? (and exhausts with a 0.004" 'no go')
 I'm just throwing stuff out before you tear into it

So,after tearing the head off I discovered an exhaust leak on cylinder 2.As I stated the carpy exhaust wasnt exactly easy to fit.Would not seal no matter what.But that doesnt explain the smoke.It explains the ticking.So I have new valve seals so I am going to put those in.Should I or should I not pull my cylinders??I took pics and will post on monday(work)Anyone out there with a carpy exhaust have trouble getting it to seal?I am beginning to chill out on the whole matter,nothing that cant be fixed(as long as you throw enough money at it)AND I am learning.So is it rings or valve seals for the smoke??? ???

I am almost sure that I put the camchain on one tooth over to left/or right.Also the exhaust leak wasnt just soot or carbon it was greasy wet???

Better pull cylinders and check if top land has trapped ring. (highly unlikely but would suck if it has)
Also check valves didn't tweak and crack valve guides.
 How did you manage to get cam timing out?
 Forgot to pull chain tight on front run?

I found my sprocket was over a tooth.ex valves hitting pistons. >:(.No damage though. :-Xredid it,adjusted valves(again),new gaskets,set timing,bigger jets in carb,Runs like a swiss watch...(I mean,a HONDA)Actually is running great again.Rode to work this morn,70mph freeway cruising ,the bigger jets with the carpy pipe really is a noticable difference,I went from 105 to 110 to 130 :o(only ones I had layin around,figured what the heck)Finally when I get on it between 70-85 mph there is power,what fun. ;D
