  1. YAFMS, PC5 and ECU tuning.

    01-03 600 and 00-03 750
    Hey, guys. I picked up a GSX-R 750 K1 a few months ago and would like to get a power commander for it. It has a yoshi rs-3 exhaust on it, but there's no lean condition on decel and the throttle response is choppy-- which leads me to believe the bike was "mapped" with a YAFMS (yosh box). Is there...
  2. Great power gain!
