2007 Yamaha R1 - Vibration + Cant get full top end
Got an R1 with 49xxx kms atm, had it for 3 years , not used a whole lot but some "fun" riding whenever time allowed. Recently got the clutch plates done but have ran into a problem, after about 7k rpms the engine feels like its not free ?(like its biting into something)? causing alot of noticeable vibration, the bike felt very "free" and smooth in its higher rpms before that, even in corners i can feel noticeable vibration under my footpegs. Ive played around with clutch cable settings and free play but nothing really solved anything. The bike was tipped last year but there wasnt any damage , could the shift pedal have bent or something ? (ive looked at it and looks fine, not sure if i should mess with it).
Also this morning i tried to open it up in 6th gear but the bike wont push past 260-70kms , didnt feel like r1 power
What other causes could it be ? Valve adjustments ?
What would be the thought on rebuilding the engine ? I love this redheaded child of R1 family and would like to bring her alive again
