I bypassed the pre-muffler, carbs are cleaned (by the shop off of which I bought the bike so I'm not sure how well), cleaned the air filter and replaced the seals, there are no leaks of air or exhaust, the valves are adjusted, new coils, plugs, and wires.
My FIRST "running" question has to do with back-fire when the throttle comes off from high revs; for example when I accelerate "hard" in second gear up to, say 6500 RPM (and she's got a NICE snarl up there), and then come off the gas suddenly, on the deceleration the motor will "pop" and "back-fire" a few times on the way down to lower rpms... it sounds cool... but is this normal?
**** I just found this thread: http://www.thegsresources.com/_forum...light=backfire (should have looked more closely). Asked and answered!
Here are some pics of yesterday's work on the coil and exhaust and the final product taken just after my first ride:
