    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

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.
