BAD shaking front end!
aah! ive been trying to fix this for a long time now, hopefully you guys can help.
So i got my beautiful 2007 cbr600rr in October and it had a salvaged title. It was stolen and has damage on the left side: clutch end rash, bar end rash, passenger and drivers peg, rash on left side of front rim, engine casing rash, and back turn signal rash. The seller said that the right bar assembly was replaced and i can see marks on the rite side of the frame where the handlebar had slammed into the frame (like if the bars were turned to the right and slimmed into the frame). It has all new farings so i cant tell what else was hit. I bought the bike with 1000 miles on it and it has 2200 now. I noticed this problem soon after getting the bike and it has been bugging me ever since.
I am getting violent handlebar shaking at speeds above 40mph. it is hard to tell but i think that it gets worse as i go faster. Anything above 80mph is really scary. The shaking is not to noticeable with both hands on the bars, but when i take one hand off or both hands off, the bars shake really bad and you can feel the whole bike shaking. It seems worse with moderate to hard engine braking.
SOME THINGS I HAVE NOTICED.
Maybe just a little bit of break pulsing when i use the front break. Also, when im riding and look into the mirrors everything is blurry. This is caused by the vibrations in the front end i guess. But the mirrors get alot clearer as soon as i hit 6k rpm, or if I hold in the clutch. im not sure if the mirrors stay clear with higher rpm or if it is just 6k rpm...
THINKGS I HAVE DONE TO FIX THE PROBLEM.
I have taken the bike to a few shops and have heard many different stories. One shop adjusted the front forks to be not at the same height (as in if you look at the top of the forks they are sticking out of the top of the top triple tree different amounts) One shop thinks my problem is caused by a small patch of rash on the left side of the front rim. One shop said that my front break rotors were bent and showed me that my wheel would not spin freely. I took the front calipers off and the wheel spun freely. So I got a set of rotors from ebay that said that they were straight, and I put them on and the situation did not improve so I returned them. I got another set and they rubbed a little bit but it was way better. Although the new rotors seem to be dragging less than the old ones they seem to be louder. I can hear them when I push the bike or if I ride with no ear plugs in at low speeds.
Help Help Help! Any ideas on what I should try? Should I try to find a set of rotors that do not drag at all? Since I rode the bike for over 1k miles with bent rotors could that have hurt the break pads and that be causing the dragging?
Any and all thought would be really really great!
