I have a 1986 GSXR 1100 that I have put a set of 40 mm RS carbs on, and it did not run like I wanted it to, then I put a set of 38mm CV Mikuni on it, that supposedly, is THE CARBS for that bike, a match made in GSXR Heaven, and am getting sputtering at low RPMĀ“s and so forth. If ANYONE can tell me what the EXACT settings need to be, I would REALLY appreciate it. I have K&N dual filter pods on it, no air box. Thank you. cgary62
