Hey Thumperclone, This whole thought exercise was about trying to correct cam timing caused by either manufacturing tolerances or cam chain wear. Because the bike uses a crank trigger ignition, the ignition timing pretty much stays put. Having said that, I've played with ignition timing on a few bikes. On Airhead BMWs, a few degrees of ignition timing can make a noticeable differences in how the bikes run. On our SR500 racer, I spent a bunch of time trying different ignition timing settings and running the bike on a Dynojet dyno. Honestly, it made almost no difference at all advancing or retarding the timing. As for the Savage, try it. You can modify the ignition trigger mounting and get a little bit of adjustment there. There are offset keys made to modify timing. The trick is to find or make one. Of course that means pulling the alternator. On our Bultaco racer, one ignition we used made away with the key and had you move the rotor on the crank taper to adjust the timing (PITA).
