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...

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.

Resurface GS Brake Disc Rotors

OK Thanks. The rear is quite a bit thicker than the fronts. More to play with.
I want to do the fronts. Hopefully there's no issues due to how thin they are to begin with.

The rotors on the round puck brake pad bikes are quite thick. I'm pretty sure there wouldn't be any worry even if you were under the factory spec. The later rotors, starting in 1980, in comparison are a fair bit thinner to begin with so I wouldn't take those under.

BTW, the later calipers are better in terms of controlling brake squeal, but those early calipers are plenty durable since they have bronze bushings on the pivot pins.

It's a good winter project and one you won't regret. It might be cheaper to find a used set but when you owned your GS for three decades an extra fifty doesn't much matter if you know what I mean :)

....get a set on ebay.... they are the same slotted rotors used on the E, and other bikes, I think. Be sure to ask about thickness/flatness before pulling the trigger though....

Exactly. I got a nearly new pair of front rotors for my 650 with very little wear on EBay for $15 plus shipping. They?re on and they?re great.
 
As my GSX1100 is THE keeper I have had to address the issue of worn rotors and what to do about them. I had the three worn rotors skimmed and luck was on my side as they were within run-out specification this time, but they wouldn't make it for another resurface. Rather than chase up used rotors and the problems that can arise with them I bought a set of new genuine rotors to hold down papers and other things in the shed until they need to be fitted. Though not cheap I prefer to have brakes that work well and I figure the spare rotors once fitted should keep the GSX on the road for another 25 years, ha ha ha, yeah if dino lizard fuel is still affordable by then.
