Kicking Me Out of Third-Shifting Issue

Hi Guys,

So I was re-watching Twist of the Wrist II and they mentioned clutch-less shifting. I tired it, it seemed very smooth and fun. So I began doing it on almost every ride. Put upward pressure on the shifts, roll off quickly then back on and it just slips into gear. I had it down so it was quite smooth. Then all a sudden it starts kicking me out of third? Is there a possibility Ive damaged the syncros or dog collars? It seems unlikely since people race these, hard, with little or no issues. I run amsoil with LUCUS synthetic stabilizer.

Did I break it? How can I be sure my trans it in good condition?

Thanks!

It did until yesterday, but in this case I think it might have been the "Positive Neutral Finder Mechanism" because it it happened during a 1-2 gearchange. The first time It had the aforementioned issue going 3-4 without the clutch; I was able to recreate the problem attempting it again without the clutch, it did it like every third or fourth time. Normally, it shifts fine in all gears with the clutch, but yesterday, while going 1-2 it had an issue. It failed to go into second (it did the gear grind, bouncing of the gear and wouldn't go in) with the clutch fully pulled in. This only happened once. Otherwise it's had no problems. This is weird because the problem isn't consistent. Needless to say I have given up shifting without the clutch. Perhaps the high torque is just to much for the syncros to compensate for? Idk...

There is no grantee its a single problem, I ride it hard so I may have worn the syncors and destroyed the "Positive Neutral Finder Mechanism", which apparently can cause issues going through neutral.

I fond this thread which talks about it "Positive Neutral Finder Mechanism"

There are no syncro rings in this transmission.

I'd suspect you are simply having a timing issue with your shifts. Try this for practice on your timing. Use the clutch for your up shifts but only pull the lever in about half way or less. A perfectly timed shift will still be smooth as butter using this method.. in fact smoother, when timed correctly, then a full clutch pull shift, because the clutch only slips a little and doesn't go to full disengagement causing a drop or differential in engine RPM vs the bike speed. Try it, you'll see. Partial pull. This will really help you tune-up your timing.

All that said, yes, if the 3 balls are jammed or sticking instead of moving out into the slots for the 1 to 2 shift you will certainly be having trouble. Removing the balls is super easy with the case split. that being the real work.. splitting the case.

You have to split the clamshell?! Well I'm Screwed.. this is my DD, so that is just not an option unfortunately; at least not if I want to ride this season. I thought the meant remove the side cover and I was like "big deal"...

I had no idea there are no syncros In these trans, that makes me concerned I did chip a dog collar, since I could get it smooth in every other gear and beat on it pretty hard while learning to do it with downshifts. I have done the half pull successfully many times, Its what I normally use when hot rodding around, not usually when cruising though.

Would checking the oil for shavings/broken metal be enough or is there a better way to check the trans health without breaking down the whole engine?

Btw, Thanks Everyone for your replies, it has been very insightful! Feel free to pitch in if there is something I'm missing. I usually work on cars, so I could have overlooked something major...

Check for warped steels in the clutch. Had this happen with my Gen 2, installed new clutch and all is well.

YOU WERE`NT USING THE FUCKING CLUTCH FOR DOWN SHIFTS AND YOU WONDER WHY YOUR TRANSMISSION IS BROKE.
