Re: New (old) stuff
Numbers from the 48 are in
I'm referring to zero degrees as TDC
Exhaust port begins to open at 110*
Transfers begin opening at 120*
The intake port begins uncovering at 50* before TDC, and (duh, shouldn't have to say this) closes at 50* after TDC.
Both the exhaust and transfers seem to extend a little below the top of the piston when at BDC.
I also checked the piston/cylinder deck height clearance. It measures in at 0.085" (at the crown of the piston.
I should have checked the cylinder head volume while I had it off, but I was too busy polishing the inside of the head. Then it got below 40 and I took my southern self inside.
Never stop wrenching
