RZ/RD 350 & Misc. 2-Stroke Tech BBS

Hello

I have a RZ350 1990 F2 bike.

I need to do chain and sprockets on the bike , I am trying to find out what the stock gearing is for this bike .

I believe it to be 17/39 Does that seem right ?

Who makes the best sprocket for the bike ?

Sprocket Specialists ?
SunStar ?
Vortex?

Also i am trying to decide on a chain ... AFAM or RK?

AFAM 520XRR or 520XHR2

RK 520 MAX Z or 520 MAX X

Thanks in advance

Also wanted to replace the chain guides ...

Seems like they are NLA, any options ?

Thanks again

you'll have to make your own guides, some have used a bit of chopping board, but really someone should get these redone now... they'd sell...

17/39 sounds correct. check your model in the parts book to be sure.

Regardless of chain brand, I prefer a standard chain over an O ring chain.

If enough ppl bug Roger for chain guides he said he might do them. So start messaging the man.
