Hey im new to the forum and have looked for quick a while to find my specific problem, but no luck. So here's the deal, i buy this bike last fall which had a stutter only in the lower rpms. thought all that needed to be done was clean the carbs so i bought it. took it apart this winter and cleaned the carbs inside and out, put in new plugs, fresh gas. put it back together and still the same stuttering, but now it also hesitates for a good 2 seconds at about 4k rpm when i open up the throttle, then itll get back on track and wind up fine. all of my friends are speechless and id rather not get raped by bringing it in and having someone look at it. any suggestions?
