Screamin' Eagle Adjustable Ignition settings

[todd10]

Trying to finish out my set up on the 95" twin cam, .257 cams performance heads 45 mikuni, vance & hines true duals w/samson rolled thunder oval slip ons. What would be a good set up on this adjustable ignition? I have it set on curve 3 with -9 advance and 6000 rev limit. Any help would be greatly appreciated!

We've run curve 2 or 3 typically but with only about -2 on the timing. Try ramping up the timing until you hear detonation and then back away from that.
