I changed the carb on my old 200 yesterday and noticed while its idling that the crankcase vent hose has a steady pressure coming from it, the trike doesnt smoke or use oil at all. Im just curious as to how much base pressure is normal?
I also have a popping back into the carb at idle, not loud, just irritating. sorta like rrrrrrrr,duh,rrrrr,duh,duh,rrrrrr sorta thing :D :p (hows that for a description?) so whats the cause of this? do you thibk the base pressure could be a leaky head gasket going into the t-chain area? or?

Valves are my guess.

Sounds like you've got excessive blowby. The rings and bore are most likely shot, causing the case to become pressurized.
