So I've been fighting with tuning since I rephased my motor (8 years ago?) At the time I checked the cam timing and found it 2.5 - 3 degrees retarded (if memory serves) thought how bad could it be and put it together. Re-measured last weekend still getting the same 2.5 - 3 degrees retarded. Now to the actual question, I'm thinking I want to advance my cam 3-4 degrees and I just want to run my numbers and logic. To move 4 degrees on the degree wheel on the crank I need to move 2 degrees on the cam? The cam needs to move clockwise in relation to the sprocket? And finally I came up with 2 degrees at the diameter of the flange that the cam presses against should be about 1mm? Sorry to be so long winded and thanks in advance.
