So I was talking to a friend today that said the timing on my 103 may not be as sensitive as I thought. His theory is that you have roughly 4mm of stroke while at top dead center. This in theory gives you 2mm of play either direction when setting the timing? Sounds shit to me but I just wanted another opinions.
I micrometered mine and right now I'm about .66mm BTDC. It seems to be running great but my question is will it gain power and speed if I time it to exactly 1.44 BTDC?
