First i removed the timing chain at TDC and installed the adapter hose to the spark plug hole. Pumped up the air regulator to 100psi, then connected to the
cylinder adapter. Honestly, I have very little if any leak down. Maybe 1-3% at best. Using an automotive stethoscope, i listened at the exhaust, the carb intake, the exhaust head pipe,
and could not detect any leakage. Obviously, the valves are sealing, as well as the piston rings. No bubbles in the coolant either.
Question, the bike will go from being full of oil to almost empty after 20 miles of single track. I have absolutely no leakage externally, nor does the bike smoke.
Correct me but as i see it the only other way oil could be lost would be due to faulty valve seals, or valve guides. The intake valves clearances are all about 0.00mm. and need adjusting. The exhaust valve clearances are in spec.
But again, the combustion chamber will hold 100 psi all day long.
So where is the oil going?
This did not occur when i first got the bike ... say 20 riding hours ago.
