Stock cylinder porting?
Posted: July 13th, 2010, 5:12 pm
Can anyone tell me what the transfers and exhaust degree at on a stock 89-01 CR500 cylinder? I'm at 119* on transfers and 187* on the exhaust. My bike seems to run pretty good, but I am kinda wanting a little more out of it. Hillclimb bike only. Most hills are wide open speed hills, shifting to third.
