CBR600RR Trouble

Well as many of you know, beginning of last summer I sold my 919. Purchased my buddies cibber. Well, I ran into a lot of financial trouble and haven't had a chance to rebuild it yet. A few months ago some real crap happened.

When I pushed the shifter down when it was in first it would go down like a had another gear, but didn't do anything detrimental. Now it won't shift at all, but the clutch works just fine. It's stuck in 3rd or 4th... The shifter goes up and down, and feels like it's shifting but it's not. I was told by a buddy that it is probably my shift forks, because this bike has been down quite a few times.

Any ideas? If the shift forks are bent, does anyone have any detailed advice on replacing them?

I just want to get it rideable, and this summer hopefully I have the money to fix her up all the way. Not sure yet, but I'm also debating selling it, and *gasp* getting a Harley after my next deployment...

why in the world would you get an overpriced under powered POS....

There could be lots of things that would cause it not to shift... its probably a shift fork... but you wont really know untill you tear it down.

It's either the shift spindle end of the shift shaft or the quadrant on the shift drum, both of which are accessable by removing the clutch cover. If it was the forks or anything else inside the cases it would still shift, but not properly engage. On the Ron Ayers microfiche Ronayers.com Fiche Desktop Motorcycle Honda 2005 CBR600RR GEARSHIFT DRUM it's either index 6 or 10.

This sort of damage is fairly common on bikes that have been crashed on the left side as it sometimes fractures the blade of the selector arm, then continued use flexes it until it fails altogether. It's a comparatively inexpensive repair, and dirt cheap when it comes to transmission problems.

Rob knows his stuff. I'd listen to the man. Do you wear a lab coat when you ride? Or mechanic's blues? If I ever have anything I can't tackle on my bike, I'm going to send you an email before I waste time anywhere else.

Thanks Rob. The last time it was dropped hard was on the left. So I guess the next day I have time to fool with it I'm taking the clutch cover off, and getting dirty.

Do I need to drain the oil first, being that it is a wet clutch?

It was only $1,800. And I wanted something lightweight, easy to work on, Honda reliability, and something I could turn into either a stuntbike or trackbike.
