FYI, and I know this comes a bit too late, forum member OLEG makes an aftermarket output shaft out of high quality, aircraft grade metal.

Also, Hyosung revised the front pulley design. Earlier models had a much narrower spline on the pulley. In later versions the spline surface area was widened. I don't know how much that matters in your case, as I am imagining a scenario where the pulley shore between the weight reduction holes.

Ok. Ghetto albert to the rescue...
There was a guy here in texas the welded the sprocket to the shaft.
 He had just enough teeth to get it in the proper location.  2yrs later still holding up fine.
It was on an st7

I only saybthis because u only have 1 choice right now. If it works great.. If not u didnt lose anything u r still going to have to change. Split the cases.

I like it!

There really is nothing to lose in giving it a try. Don’t overheat the shaft though.

Yeah I was thinking of a tappered shaft and fitting a woodruff key way in and see how long it lasts. And part number 33 was as thin as paper.

Shaft can be replaced without having to split the crankcase.
All done from the clutch side.
Drain oil first and then lay the bike down on its left side on some big interlocking EVA foam mats.

Eh?

You sure Hylife? I'm pretty sure the crankcase needs to split. If I am wrong though, I'd love to know how!

Would love to know too 100% before I buy the parts. Not doubting you Hylife but a bike mechanic said it's an engine out and split job.

Woops. Brain fade. Gotta stop surfing the forum when I should be sleeping.
Don't know why but I was thinking of the clutch replacement even though the OP clearly stated the drive shaft.
Sorry, my bad.  :o
Yes, you need to split the crankcase to access the gears, their forks and the drive shaft.
