Yessir...I can check the valve clearances again.

Hope your right about the smoke.

3rd go...top end coming off again to see why it’s burning oil...pretty sure I damaged the exhaust guid seal...so new one going in.

Verified the exhaust guide seal leaking....theres evidence of wet oil on the valve below the seal.



But another bad thing is....(as david guessed) I likely didn't have the lash set correct...and the rocker faces have some damage...cam lobes look good though.



new rockers ordered.  All else looks good.

Replaced the Rocker Arms, Exhaust Valve Guide Seal, Adjusted lash and timing. Fresh ethanol free gas and cleaned out carb.  So far so good.  I let it idle for about 10mins and no sign of smoke.  Just water vapor as its very damp and cold outside. 

Need to:
- Change Oil
- Check Cam Chain Adjustment
- Button up small items and hopefully its good to go to just park and ride around
