Problem shifting into 2nd gear.


Recommended Posts

Posted

Ok so this is a serious problem (if I allow it to be) now and looking to find out if this is normal amd perhaps my technique or does it need to be looked at...


Up shifting from 2-6, perfect at any RPM.


Dowshifting 6-1, perfect.


Upshifting from 1 to 2 low RPM - clunky but ok.


Upshifting from 1-2 high RPM - possible death sentance!!!


It locks into neutral at higher RPMS, one time I shifted from neutral to 2nd (whilst going about 50mph and the rear wheel locked.


Happened again today, changed at about 14000rpm and went into neutral with a big clunk. I decided I wouldn't risk it this time so coasted until I hit about 30mph, then changed.


Having done a bit if research I'm seeing possible broken teeth? Also, don't know if it's relevant or not but in the service history there is fixing a broken gear link (doesn't state which one).


Any ideas???

Is your chain tensioned properly , notice on my bandit if loose gears are not so easy to change.

The R6 is known for 2nd gear problems!!


it could just be you not been very positive with the gear change

***update***


So I'm beginning to conclude it being my technique rather than a faulty transmission...


After reading about on the net, I found that 1st to 2nd needs a slightly different technique in order to shift smoothly. After trying it and being successful at 10000rpm I can say that up and slightly right rather than straight up makes a big difference, most of the time I didn't even notice the 'problem'.


Haven't tried it at the highest engine speeds yet, I want to be confident inthe shift before going for it.


I'm out and about today so will get some nice stretches and keep trying and keep the thread updated in case it helps others...

So basically you're telling us that you rag it everywhere. :-)


Are you clutchless shifting?


Kinda interested in why you're going N-2 at 50mph - I'm not surprised the wheel locked if you dumped the clutch with low revs!

Just 90% of my ride!?!? Just kidding, but I didn't buy an R6 to stay at 4,000...

No, engine is well and truly disengaged.

I guess it wouldn't have locked if I went N-3/4?? Why did it lock anyway and not just get massive engine breaking??

3/4... Probably not.


You are getting huge engine breaking when you dump it at low revs - enough to overcome the traction of the rear wheel!


On track (of course :-)) it's quite common for the rear to lock/skip up a bit under harsh downchanges - watch motoGP or something and you'll see them squirming about on the run up to a corner.


Maybe try giving the throttle a blip before you let the clutch out or quicken your shifting a bit (sorry if I telling you how to suck eggs!).

Not at all - thanks for the advice!


I'm still getting used to the massive torque I'm not used to - my previous fastest vehicle was a subaru... the R6 is a monster compared to it so any advice on the mechanics is very welcomed.


Ok that's great, so at least I know if I don't shift properly, I can just go up a few gears and I will live to see another day. Probably do that rather than blip at this stage until I master the power etc...

This might be interesting with regards to "blipping" throttle:

Probably and old hat, but explained nicely.

Ok so I'm embarrassed and relieved to say it was my technique. I can conclude that at least on my bike, at high revs in gear one, an aggressive, upward and slightly right thrust is needed to change smoothly.


Tried numerous times up to 13,000RPM without a problem.


Relieved it's not a gearbox fault... had them before and they have a very negative impact on the wallet!


Thanks for the help all, appreciated.
