I just bought a 1999 GSXR600 and I have this problem: It idles really rough. It runs OK above 5k. After it heats up to normal temp it idles high at lights around 5k and I either side idle adjust it or slip the clutch to pull the motor down. When I first got it it the exhaust wreaked like it was blowing at least 50% gas out the Yoshi pipe. Its improved alot but it still gets suckass gas mileage and runs like shit. I dont wanna give the local stealership $800 for 45mins of carb cleaning but I don't wanna F it up on my own either. Any exp. help would be appreciated.
