when the revs are really up in first gear(9000to10500) the bike sometimes misses the shift to second, mabye the bike mabye the operator, but after the shift is missed i almost have to stop to get it into second, otherwise it just grinds. is this a normal problem on the older canes or is it a specific problem with this bike? and if so what might that problem be? thanks my fellow cane enthusiast

 

That happens to me sometimes, I notice that if I do a lazy gear change from 1st to 2nd

 

It shouldn't do that, though I rarely rev my bike that high. Try checking your fluid level in the clutch reservoir- if it's low it can make shifting difficult.

Two other things come to mind :
1 When did you last do an oil change on the bike ?
2 May be some wear in the selector shaft or dogs.......?
CBR's do have "lumpy" gearboxes, perhaps you need to be a bit more positive with your gearshift.
I've had it happen twice, and it was due to my not tapping the shifter forcefully enough - hard to describe but you can sometimes hit neutral and then it'll grind if you try to bash it in while it's still moving.[X(]

 

yeah its not really a force problem, always go for a good solid shift, sometimes it just doesnt complete the full shift, a few times even at lower rpms, clutch fluid is all good, checked this morning.

 

need to changes the clutch and press the clutch lever all the way when u changes the gear to avoid grinding gear...
