gsxr rockers?

[paco13]

Hello,
I will be replacing my cams and need to replace my rocker arms.
I remember people talking about using gsxr rockers on the GS1100 engine as an upgrade.
Question is, What arms (year/model) should I look for, and do they fit staight on with out any mods?

Do you need complete shafts or use the stock GS shafts?

When using higher lift cams (365"/370") will the oil bump need to be ground like with stockers?

Any difference in lift ratio from stock?

Thanks in advance.

86-90.
Bolt right on.
Stock GS shafts.
Very close to same rocker ratio, as in within .02 on the ratio & they vary with manufacturing tolerances.
No oil bumps to grind off.
They are lighter & stronger!

Excellent!! Thanks Ray
would you suggest I buy new? I will be using new cams.

I'm running a used set for several seasons without a problem. I went to them so I didn't have to run the longer adjusters.

I've used used ones that I inspected & deemed good to go but for about 40 bucks each for 8 of them, if you can afford new why not? Ray.

Thank you again for the advice, I am going to go with new ones.

Have to go through and see what else I am gonna need. while I'm in there.
I have a 750 2v engine out in the yard I'm gonna rip the oil pump gears from and might as well buy a new pump while I'm at it.
As well as one of those top oilers from ebay.
