I have a 99 Yamaha R1 that I bought with about 5800 miles on it and I have put about 4000 additional miles on it. Well evry so often when getting on it in second gear it would act like it was in gear until about 4k+ rpm then it would over rev for a split second(like it went to neutral)then act like it was back in gear. This only happened maybe once a month. Well I let a friend of mine ride it while I rode his Gixxer 1000 and he was trying to do some wheelies on it. When we stopped he told me that it had done the smae thing to him and I told him that it happens every so often. Well....after I got back on the bike it rode fine until I gassed it in second and it completely felt like it went from 2nd to neutral back to 2nd. Now anytime I push it hard in second it lets go above 4K rpm but *only* in second. 1st,3rd, 4th, 5th, and 6th all seem fine and second acts just fine unless I give it more then 3/4 throttle and then it lets go. Anyone have this happen to their R1 and what did you have to get done to fix it???
