80/90lbs seat pressure,240/260lbs nose(open)pressure will handle 8000rpm.sounds like to much pressure or not run in correctly or lack of lobe/lifter radius not right.

inlet valve sizes 40/41mm, ex 33/32mm depending on bore size,if bore size is 77mm or less, 41/32 valve are best so the exhaust doesnt hit side of bore. u may need to relief the bore if u go bigger exhaust.cheers
