Something Failed, let’s find it! Transmission Analysis.

No idea.

It will not be cheap, though, I imagine you could handle the welding to the drum required yourself and save some coin lol.

start taking interested parties phone numbers ... willing to fork over the coin .
this forum has seen a lot of captains wanting a 6th gear .
i have to decline though, spent enough as it is and still not satisfied with my trans. or maybe it is something else I do not know anymore
 
6th will be a winter project.

For now I’m wholly consumed with getting both bikes in fully maintained running order again!

CAD drawing of the new gears will be the first step, which, I can’t start until I get my trans back and measure things.
 
I call dibs on the gearbox if you blow the engine up!.
 
Rob - did you see @Ishrub message about an r3 being parted out because it has a blown 5th gear. ?
 

Personal opinion, trying to add a 6th gear is worthless, as every thing else would have to be decreased in size to make room. If you look closer, even changing the ratio of fifth will present problems on the output shaft. What I would do (so you did not have to redesign the whole engine case) is look at flopping the tooth ratio between the two helical gears. It might be doable but the ratio change will affect all gears. Because it's a set of helical gears you will have more tooth elements to play with yet keep the strength thanks to the helical mesh. Might even get away with changing the modal pitch of the teeth. Diametral pitch for us non metric fellers. It would be well served if everyone would see the main thing you can not change without designing a new motor is center-to-center distance of the shaft in the engine block. Once you research that and understand a little thing like gear design theory, you will just cease thinking you can just add another couple gears plus a different shift drum for more shift forks and all the new detent wheel and associated parts.
 
if it could be done a 5th gear change would be great
if u could downsize the gear and change the teeth count then u would not have to change the shifter parts.
