Thanks for all the input for my clutch problem it helped.
After removing the transmission to service the splines I removed the air injection system from the cylinder head and air cleaner box.
Next was the oil leak problem from the pushrod tubes so off with the exhaust system by cutting off the exhaust nuts to save damaging the heads.
Off with the heads then removed the valves to get all the carbon off.
New pushrod tube seals installed then all back together.
I did find that the plastic thrust bearing holder was .001" OS so I sanded it down to put it in spec. I think this also was part of the problem with the clutch grabbing when things got hot. The clutch now works smooth as silk.
This was all worth while as the bike is now running the best since I have owned it.
Cheers Bob
