I just did a high compression piston and bigger cam. I'm going to be tuning the carb and noticed nobody talks about adjusting the ignition timing. I'm assuming most bikes of the '06 vintage have some sort of HEI distributor-less ignition system but can someone give me more info on how the bike "knows" when to ignite and if there is any adjustments that should be made? Please don't be afraid to get technical! Thanks
