Re: Tps adjustment
Bugmans gsxr says this is a side effect of the PIAR MOD
An unwanted side effect of this mod is popping on deceleration. You'll now have loud popping and crackling of the exhaust whenever you rapidly let off the throttle. That's simply because without the PAIR valve opening on deceleration, much unburnt fuel exits into the exhaust stream, and ignites part way out of the midpipe. So your bike will sound like a badly tuned Hardly-Ableson, something I really did not find desireable.
