How do you figure the auto advance will retard the timing an additional 3/8" by advancing the spark? That's how my bike is timed and it runs great.Scottie
Thanks, Scottie , I wasn't 'having a pop' at you, by the way, but it's important to have [and give] the correct information, especially with things like timing. B.W.
I thought he was talking about ignition timing not valve? ERC
That would give you piston travel but not the ignition advance degrees. ERC
