    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...

  • Returning Visitors

    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.

Valve adjustment questions

Any of these GSes will do 11,000 just fine, especially the smaller ones.
Never had a shim come out.
 
I wouldn't know, I never had a shim-based GS.
My GPz is still pulling at 11k, but the rev limiter kicks in and I am done. Hit it while I was chasing down bwringer on his GS 850 and it surprised me a bit. The rotating assembly is balanced and I have read they can approach 15k, but my GPz 900 ignitor has a built-in rev limiter.
 
Daaang. That's amazing. Rev limiters... well. they suck, but they can also save your bacon.

I've gotten a 2.50 shim locally, and I've now got a .013 clearance. Is that too big? Only one other is nearly that size, and it's .011.
 
You need to send an email to Steve and get a copy of his valve adjustment sheet. It is used during valve adjustments to record current clearances and shim sizes, new clearances and shim sizes, and is really handy for figuring out what shim needs to go in next. Just get a copy from him, print out several copies and use them, and now you will have a record you can use when you go to check clearances the next time.
 
I've got it, and got it filled out. It was helpful to do them en masse. I got 3 shims from him, swapped some others around, and just wondered if .013 is too far over the spec. Some people mentioned running at .010, so I wonder.
 
Not sure what the spec is on your bike. They recommend going to the edge of the widest gap, because the gap will decrease with time.
 
Spec is .03-.08 or .09 (I forget which), but a few people said they run them high - like .010 or .011. That's not far from .013, but I don't want to cause any problems.
 
The published limit is .03mm - .08mm on all of the shimmed engines as far as I know, maybe the twins are different but I doubt it. A lot of us use .10mm as the upper limit. I might go .13 as a temporary fix until the right shim arrived, but not if I didn't have to and I wouldn't wind it out much with that shim in there either. I don't know if it would spit a shim from running at .13mm (probably not) but I'd rather not find out.

The clearances don't ALL go smaller with wear, mostly they do but not always.
 
Thanks. I'll switch it out for a slightly thicker shim tomorrow.
 
Bah. The local places (I tried 4) didn't have 29.5mm diameter shims for the most part. The one that did had some 2.50, some 2.60, and no 2.55 or 2.50x.
Guess I have to wait on the mail.
