    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.

see picture of service manual of the GS1100, found on Basscliff's site...

confusing information, let me tell you...

can someone please finally set things straight ?
 
I understand the difference between mm and inches,
but not the difference of a Clymer (saying valve clearance between 0.03 and 0.08 mm) and a service manual (saying between 0.07 and 0.12 mm)
 
Always used the imperial settings in the service manual. I don't use Clymer manuals. I have found them to be less then helpful in the past.
 
The clearances shown are for the 16-valve engines.

Yours is an 8-valve, so it remains at .03-.08 mm. :o

.
 
Ah but really they're both 'right' in a way. Ideal is probably .6-.8 mm, where .3 is really pushing it, and .12 is loose on the loose end but works fine. I was told many times that if it's below .6 just go to the next size up and let it be loose for a while. Loose is fine, it's just noisier, but tight is bad bad bad.

WATCH YOUR NUMBERS, Allie. :eek:

Make sure you have a ZERO to the right of the decimal point. The specified clearance is .03 mm to .08 mm.

Gert's numbers are correct, but not for the model bike he is working on.

Hey they're just zeros, what do they amount to? :-\\\ I understand about the models, but my point is correct isn't it?
 
I shoot for .04 - .08. If you have a bunch of shims like me,:) it's pretty easy to find some in between sizes to get the clearance just right. Loose is better than tight, but within spec is better yet.
