Which 15T front sprocket?

I wanted to down gear my 1979 KZ 750 a bit by going from a 16T front to a 15T. Z1 has a bunch of 15T sprockets. Is there any special requirement or do all the 530 chain 15T sprockets fit?

EDIT: having done more research, it appears the JTF513 is the one that fits the 750 twins?

you are correct they use the same spline on the out-put shaft just make sure to use the lock tab on the washer and clean the threads really well and red loctite the nut on and you should be fine.

dont forget a chain and rear sprocket

looks like i forgot the most important thing -payback for out bidding you on that cal-fab swingarm right.

thats alright ive already got one someplace i bought in early 80s that i want to make copies of!:laugh:

when you get some of them made up let me know and i'll get 1 or 2 from you im planning to build a vintage superbike for geezer road racing. i've got the engine pieces and the frame im going to use i just need forks and swingarm,i know another project. i never could focus. i found out i had a.d.d 25 years too late.

ive got S.A.D.D serious ADD !mine is 2 over with airtank,just need to find the box :blush:
