gear selection

zx6r b1h sometimes wont go down the box and sounds like it just wont connect with the gear even when i tap the lever down more than once, only happend twice on the road as im slowing for a bend also two times on a track day which gave me a bit of a moment.

Gear change problems

These symptoms can be typical of improper chain tension and also worn cush-drives.  It is also worth checking your gear linkage to make sure that it is not siezing.  Lastly, is your clutch properly adjusted?

Hi Micepunk

If all that MM says doesn't seem to do the job? you could have a worn gear select lever shaft,if the two dogs on the shaft don't push the selector cam change drum around enough to drop into each cam cut out it will sit on top of the lobe effectively not selecting the next gear or finding a false neutral.This can also sometimes occurs if you leave some pressure on the gear shift pedal(unknowingly)effectively pushing the selector drum around enough again so the dogs on the shaft  pushed the selector cam onto the top of the cam and not into its next cut out.Hope this makes sense,i know what i mean its just hard to explain it when writing it down?.Good Luck

Hi again

It could be just poor adjustment so check all that out first(what MM has said),if it has good quality new oil and filter as well but is still doing it,but with you now saying it not making it into first gear every time,its sounding more like a selector dogs on the gear shaft.There about £80 new from a main dealer,and about two hours labour if you don't do it yourself,but do exhaust all the adjustment ideas first .Good Luck

Shift.

Factory Pro's Star Shift is an interesting product (-anyone tried them?) and there's a video at the bottom which might support kcmc's dogs 'n' drums description, I dunno.

(Edit: Actually I don't think the video helps here, the action is going on behind all that gubbins. Again, I dunno.)

Thanks

for that James,that's exactly what am talkin about,i have never fitted one of those after market star shift roller type arm and heaver spring,but its no different fitting one of them as fitting a standard one.I have ridden bikes with this fitted and yes the gear shift is a lot crisper and more precise,but if the shift shaft is now worn this will need to be replaced to reap any benefit.Good find though James:biggrin:.
