Hello, just picked up my 4th hayabusa, its a 2004 with 40,200 miles on it & was used as a sport tourer before me purchasing it. 100% all stock and all in all in very good shape. The problem is the bike suffers from a weird idle and cannot be syncronized due to the #2 cylinder butterfly not fully seating like the other 3 cylinders, cyl’s 1-3-4 are all in line with one another but two is a no go. I also noticed the cylinder has more carbon as well, I have never heard of an issue like this, i sure was wondering if anyone had some knowledge or info on whats going on. my 00, 03, & 08 never suffered from anything like this. Also this bikes clutch basket sounds horrid too once fully warmed up.
