Get a new petcock

petcock issues would cause this issue? or are you saying to illuminate all the problems?

They're saying you have a host of problems, which is not uncommon for a 30 year old bike

That's why BassCliff has all those tutorials on his site

Currently, you should check:

1. Petcock =leaking gas into the crankcase
2. Oil in exhaust - leaking valve stem seals or piston rings
3. Climbing idle - leaky intake, carb clean, airbox seal
4. Uneven performance - adjust the valves

It's time for some further diagnosis and wrenching, keep posting up what you find
