Question 05 cbr rr 600 shifting problem

hey guys qucik question for you? may be really simple answer im just not mechanically inclined lol. i have an 05 cbr rr 600 and when shifting using the footpeg.. when i shift up into gear sometimes i have to shift it up then slightly tap down on the foot shifter for it to go into gear. its almost like it shifts alittle over the gear. once i push it down just a small tap it works perfect. is this an easy fix or a major problems? any help would be greatly appreciated

That doesn't sound simple to me. Your shifting works like this...

The shift drum changes your gears by rotating and it moves the forks in the tranny which changes the gears. On the shift drum... there is a star shaped thing with a spring loaded roller pushing on it. This roller with the spring tension on it rotated the star from one low spot to the next low spot. When you shift, you rotate the shift drum and star shaped thing to the next low spot in the star. The spring loaded roller stops the drum in the low spot.

Here's the tough part... the roller wants to stay in the low spot. Even if you rotate the drum a little past the correct spot for that gear... the roller will still go to the low spot.

The only thing I can think is that the star shaped part or the roller is messed up to make your problem happen. but with those being messed up... I don't know how you could even ride it.

Do you have a rear stand for your bike? I'll need some more details to really help you out but you need to be able to spin the rear tire so you can shift the bike from gear to gear.

unfortunately i dont have a stand... but i was told by another person that what could be wrong is there is a spring in there and being the bike has approx 20 thousand miles on it the spring could have worn down and need replacing... does that sound like an option for being the problem too you?

^^^Sounds like it could be the spring for the roller. I just replaced the shift star, roller and spring. I have the OEM parts with under 2k miles on them if you are going to need them.

It sounds like it could be the spring and roller but I didn't want to just open up the motor if it was something else.

w/o a functioning roller. I'd think it would just jump around between gears or even just change gears. It would seem impossible to ride with that being the problem.

Parts should be cheap... the labor will be the killer if you're going to take it to the shop. You at least have to pop the clutch cover. I don't know if you can reach behind the clutch basket to fix that... you might have to remove that too.

Yep, the basket has to come out as well.

its a good idea to replace it too,
because if it snaps it wont stay in gear.
And you dont want to loose that in the sump. (early R1's had this problem)

maybe, just maybe its a sign of premature wear.

cost erm the spring quite cheap, it depends what covers need to come off, it may be simple as one cover, and the shifter linkage. I'd say max of an hour with riding time.

But im not sure on the cbr just how easy or difficult it is.

Right side cover (clutch) has to come off, destake the enter on the clutch basket, remove the clutch basket, remove the bits in question (shift star et al) and then replace all of the above - my bet is a shop would tell you 4-6 hours min at around $75/hour plus parts - then again a new motor and trranny costs more....it reeeaaaaalllly shouldn't be doing that - could also be a bad shift drum or bent shift fork
