I guess that's a busa thing. Mine's an 03 and I bought it used from a guy who apparently ragged on it. I got it with 10,000K and when I got on it hard in second and get up to between 3000-4000 it sounded like I red lined it and it was powerless, so I was skipping it completely after that. A few months later of doing that, I would be cruising down the road and all of a sudden my rpms dropped, the bike would start slowing down (didn't shut off) and then catch back up. The first time it did that I was on the freeway, didn't let off the throttle and when the rpms jumped back up it nearly bucked me off. Well, turns out 2,4,5,6 gears were chewed up and I had to get all of that replaced. $1700. My brother-in-law almost bought a busa last week and my husband and I told him to get on it in second gear- sure enough it did it and he didn't buy it. Short story for the day!!
