New Ninja popping into N while riding

[cameltoe]

In the last week or so the ninja has popped out of gear must be about 9 times at a guess, usually when its been riden at a brisk pace with high RPM, it has happened in most gears from 2nd to 5th but not 1st, It did it 3times while riding yesterday. I have read on some forum that other ninjas have have this problem tho its not very common. Could I be wrecking the trans?? my first bike but Iv growen upriding all sorts of bikes so I would think I know how to shift, one thing I can think of is on a couple of occasions where it be neccessary I have done full throttle gear changes, its at very high RPM and it doesnt fell to rough, but thats the only thing I can think of that would cause this even though iv only done it a few times, anyone know whats causing this?? by the way I have spent $80 on fuel the last 2 days. can anyone beat that?

$80 on a 250 is'nt a bad effort, just take your bike back to the shop and get them to have a look. it will be covered by the warranty

i'd delinately take it back to the shop and talk it over with them.

mine will get stuck in neutral quite often when shifting from 1st to 2nd... putting it down to noobness untill i get a few more ks under the belt. (just under 500 so far)

Used to have trouble getting it into 1st aswell but seems to be that as long as i change before I have stopped it's sweet.

Also notice that te idle RPM seems to rise a few hundred RPM after being ridden for awhile.. not sure if that's normal.

I'm willing to be it's not a faulty gearbox. More likely you're letting the clutch out before your foot has pushed the gear lever all the way or something similar.

Used to happen on my ZXR250 from time to time (only when pushing it) until I learned a handy trick.

Try keeping the upward pressure on the gear lever until you have completely let go of the clutch.

E.g. normally people do this:

1. Pull clutch
2. Click up
3. Let gear lever return
4. Clutch out

You want to do:

1. Pull clutch
2. Click up
3. Clutch out
4. Let gear lever return

Or ignore the clutch :P

It shouldnt be that difficult. Take it back and let them test ride it and tell you if its normal gearbox behaviour.

Could be your gear changing style as some have mentioned.

Here's some advice Jay Lawrence gave me for shifting. Although it applied to clutchless shifting, he never misses a gear this guy.

He said to me apply upward pressure to the gear lever before you back off the throttle for the gear shift, and it should fall into the next gear. To apply this to shifting while using your clutch. Try putting pressure on the gear lever the moment before you pull in the clutch. You will also find this majorly increases the speed with which you will be able to do your gear changes.

When racing the 600s doing clutchless upshifts. The gear changes were done in the time it took you to back off the throttle and get back on pretty much as quick as you can. It does work on the 250's too. But I'm gentler to them. I found that my forearm would start to get arm pump if I used clutches for all my upshifts aswell as my down when racing, so that was another reason for using clutchless upshifts. Also Jay pointed out to me that using the clutch while changing up in the high speed corners unsettles the bike, so a swifter clutchless upshift was not only quicker but safer too. As long as you don't fuck it up hahaha.

When I first started on my first CBR250RR, I used to get it jumping out of gears sometimes. Give it a bit more time for you to adjust your shifting style and if it's still playing up I hope it's under warrantee. I've never opened a gearbox up and I hope to never need to.

Haven't had that trouble with mine so i'd probably take it to the dealer to check out.

Is it possible you might have your foot perched a bit far back on the peg? I've only ridden this bike so i have nothing to compare it to, but i'd imagine that sportier bikes are easier to shift while keeping ball of your foot on the pegs.
As far as i can remember, on my bike i think i have to move my foot forward so that my heel is on the peg to shift properly.
The selector feels quite clunky on mine so you need to give it a good positive shove with your toe, otherwise you will be finding false neutral.

Im pretty sure you're right about this one, i've had this problem on my ninja too, flicked up a gear and blah neutral inbetween 2 and 3, 3 and 4, etc

its a tad unsettling at times.

but i've found by not rushing the gear change and making sure i actual push the leaver right up and not just half arse it, the problem disappeared

What you've described is also sometimes a symptom of a chain that's too tight.

Make sure the chain tension is checked while you have your full weight on the bike.

Try adjusting your gear selector lever downwards slightly. This will make your changes more positive. You should be able to just flick your ankle or boot tip and it will change.

Still, I think there is a fault though. It shouldn't be that bad.

I agree with Ripperjon on this, I went through a stage of changing where it didn't actually change and found I have to have my foot quite forward to make it happen every time. (Although it doesn't pop to Neutral)

This has been happening to me as well. My bike's on ~1700km now, it's happend a couple dozen times at least.
Seems to happen most often in the first 10 minutes of riding, when i'm starting to push it a bit.
I'm going to have a go with the "clutch release then gear release" method mentioned, and see if it makes a difference.
It's a bit of a prick when you push through to the front of the queue at lights, and then your 1st -> 2nd change goes bad as you attempt to race away..

[Maki]

It`s never happened to mine. Try clutchless upshifting, put a little pressure up on the shift lever and back of the throttle gently. The bike will then pop into the next gear and you can give it more throttle.
