slow gear change under heavy acc ?!

[tchallenger]

Hi guys ! , looked through the manual , adjusted the clutch drag but I still have this problem which is as follows , chisanging gear through town when bike stays below 6k is easy to change gear , the fun really starts when I try to give it the beans for example 1st gear rev to 10k pull the clutch in shut the throttle kick up but nothing just spinning and this is the same up the gear box , however if I was to only rev it up to 6k and do the same thing its all gravy ! Is something warn somewhere ? Or do I need to just learn to shift differently to my rs125 ?
Many thanks tom

lol another ex rs rider like myself... miss all those plug chops and top end rebuilds, getting a bigger carb and BANG!!!

When i get up to high speed I still keep my hand over the clutch force of habit!

In answer to your question, no idea sorry ask me one about the RS

Is your chain slack ? You'll be suprised at the affect that has I had the same problem from 1st to 2nd, its quite a gap between them

Haha I loved my rs it never went bang , kept up with my mates gsxr 400 on the real twistys, but my zxr is just <3 can't get enough of it ! I found I did the same to start now I just hang on and enjoy , did 200mile round trip on Sunday couldn't have done that on the rs !
No worries though man, just really bugging me as It just won't let me shift like I could on my rs and I don't no the bike well enough yet to know if its just me and I need to shift differently or something is up !

Chain and sprockets are new on it but the chain slack seemed good when I looked quickly earlier will check properly tomorrow , any other things it could be ?

Id adjust the gear lever, moving it down (facing the floor) helps give your foot more leverage. I don't think they'll be a problem, but good boots help

The problem to me is the clutch can't take the load of a higher reving engine under acceleration anywhere below 6k rpm I can change gear as quick as I want, above 6k say 10k it just mangles its self from 1st to 2nd and some times 3rd but this problem doesn't exist below 6k one bit !

If your not deliberate with it it does miss now and again you have to make sure your foot isnt slightly resting on it when you upshift. otherwise it dont engage. i did it a few times when i got mine, i thought the chain was coming off, but ws just poor shifting

sounds to me like the clutch is slipping....if the cable etc is adjusted properly maybe the plates are worn.should change quickly and smoothly all the way through the rev range, although i dont use the clutch changing gear as im sure most dont changing up just roll off slightly.

If someone has had the shift lever apart it might not be back on in the right position. Slip it off the cylindrical bit, move it around VERY slightly so that your gear change lever drops down a few degrees, then put it back on. It could be that the upshift is just out of range of your actual foot movement, so you're not fully selecting the next gear.

Other than that maybe the shift forks? I don't know what it it, but R6's had a problem with weak ones and it's a cheap easy fix.

Obviously there IS much more stress at 16000rpm than 6000rpm, and it must be a pisser to design a bike gearbox to be happy with changes at both rpm, but it's probably also worth pointing out that these bikes are designed for high revs, so it should really be low rpm changes giving you the problems...

I would also recommend that now is the time to learn how to use clutchless upshifts. Simply put pressure on the shift lever, then snap the throttle shut and immediatly back to the same point again - in that time the lever should select the next gear when you cut the throttle, and you're away.
