False Neutrals When Shifting Down

Have a 2007 DRZ400sm with 22000 miles. After my last oil change I've been noticing a lot (30-40% of the time) of false neutrals when downing shifting from 3rd to 2nd. It will skip 2nd completely and pop into neutral. Never happens on an upshift or any other gears.

I'm using Mobil 1 15/50 oil. Same oil I've used twice before without any problems before. Anyone have any clues at what's going on? Clutch is wearing out? I did also rotate my shifter lever 2-3mm higher than it was before as well.

Thanks!

Clutch related..... doubtful

....and is it truely skipping 2nd gear?
Often times a "false neutral" is getting caught between 2 gears (for instance it being shifted out of 3rd, but not quite into 2nd gear).
Shifter position could easily cause this problem.

I guess when it "skips 2nd gear" to get it to 2nd gear I upshift. I'm not sure if that's technically skipping or caught inbetween two gears.

I would start by playing with the shifter position.

I've had the same problem before and it started after I adjusted the shifter position. Once I moved the shifter position back, it quit doing it.

I would start there before I tore into something else.... Especially if the problem started after making an adjustment.

My KLR did the exact same thing pretty often. I never figured out what the problem was but found certain oils made it happen less.

Clutch doesn't have anything to do with that, although 15w50 isn't exactly motorcycle oil and it can cause your wet clutch to slip with extended use. There's a compound in it in greater amounts than in the motorcycle oil, and is what can cause you issues (molybdenum).

There is a spider gear in your transmission that can wear off points, and cause the problem you're describing. It is this gear that causes your shifter to have "pops" between gears, so that there is a little resistance as you go to shift and your foot can actually feel the shifter move positions. As this spider gear wears off some of its points, they become rounded, and consequently the gears don't necessarily seat properly. They can then pop out of gear or into another gear, neutral being very common.

Try everything you can first, as this is a serious rebuild, like try repositioning the shifter, etc. If none of that works, my bet would be on that gear wearing down on you.

So i moved it up and it seems to have fixed the problem. The issue now is that it's "too high." There's like no inbetween adjustment! Frustrating, i'll try to goof around with it more, but I can't get it between the too low/too high positions.

It has splines, if you moved it one spline and it's to high you need longer feet.

amazon is having a sale on longer feet, this weekend. The bonus is you get a free upgrade to a bigger .
Unfortunately, no free shipping on the combo :(
