I'm wondering if the internal linkage rod could be bent or out of adjustment (if any). ??

Maybe shift some more and verify if that pin can ever contact the the top of the slot. ??

Doesn't look like it's throwing the pawl far enough in that one direction. The shift drum and gears appear to be fine from this angle.
New video:

It's not a problem shifting from 2nd to 3rd to 4th to 5th with the pedal. (Of course I need to help a little bit to turn the outputshaft.

Almost looks like what happened to me. If while sitting you can shift into first but not back to neutral, the shift linkage is adjusted too long. Took me three case splits and bothering a friend for three weeks to discover it. In a nut shell the linkage hits the inside of the case and cannot move the pawl far enough to upshift. Possibly in the last split it could have become mis-adjusted. Sorry to say but the only fix is another splitting if I'm right. I hope I am wrong.

Thanks for the reply!

Ok, but in my case I have no problems shifting from 1st to N

Shows best in this video, I think. (0:54)

The first video showed it not shifting into 2nd from 1st, but you aren't trying that in the second video. Only 2 through 5 and back, which looks like it's ok there..

As dragon said, doesn't look like enough throw to get into 2nd. Internal rod hitting the case, I remember his post about that..

Dragon is right i talked him through this issue a while back the reason why you can go from 1st to neutral is that it is a short throw basically a half shift you are going to have to split the case and remove the nut that holds the shift shaft to the transmission so you can rotate the shaft a bit basically re-homing the shift linkage

I promise you this if you split the case and do the same test you did in the video while watching the internal portion of the shift linkage you will clearly see the problem it is a pain in the ass but overall since you have already split the case twice you should find it easier than ever

Just sitting ... Kawi has positive neutral finder, will not go into 2nd unless the bike is moving a certain speed.
Does that also not shift if the RPMs are too high? If i wind a bit much out of first before shifting, sometimes it just blocks as if a brick wall was on top of the pedal.

That is just gears not meshing right due to over rev which I doubt I have to tell you but here it is anyway over reving the engine is not a great practice and will accelerate the clock on engine wear

I usually like to be in 2nd gear before the other side of the intersection. Life doesn't always make that possible depending on various moving things and which direction they are heading.

Did anyone ever figure this out? Just rebuilt my entire motor only to go on a test ride and find it doesn't shift into second. But shifts with pliers fine. And the pawl hits the drum like it wants to shift, just like his!
