Quad bike. 110cc copy. shaft help?

[TheNewGuy]

I'm busy trying to get my friends 110cc atv (Honda Chinese copy CRAP!) back on the... field but I cant go back on my word.

I'm looking to obtain a new splined sleeve as it will be way more hassle then its worth to make one.


Its a 110 cc copy. but with a shaft drive that slips over the original sprocket spine at a 90 degree angle.
shaft is 17mm di.
14.3mm inner di (groove)
50mm in length (this can be anything over 50)

Splines are 2mm wide. groove 2mm wide. with 12 spines equally spaced

Any help is very much appreciated
if anyone knows were to buy or has one lying around
