    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.

Adjusting Valves

The 'special tool' the half-wit at the shop almost has to be talking about is the 3mm nut driver that someone else mentioned. I have one and even though it's an official Suzuki tool, the thieves at the shop only charged me $5.65...(It's worth about $1.50).8-[

It terms of "time saved" that $5.65 tool is PRICELESS.... so don't get into the cheap habit of jumping over a dollar to pick up a dime. The Suzuki valve tool is an EXCELLENT functional tool.
 
I believe that I've found the part # for the tool from Suzuki:

#09917-14920

Can anyone verify that this is the correct 3mm driver for adjusting the valves on an '81 GS750E? This part # was recommended for a Bandit 1200....are they all the same size adjuster? The Motion Pro 6-piece set was $42 cheapest I found it and this one is $4.57 from Bikebandit.com. The article I got the # from said it would be $9 from Suzuki.

I found this at the bikebandit site by searching the part #, but the part had the same # on the "add to cart" page.

I'm assuming your year is using shims.Clymer's lists a Suzuki tool for depressing the bucket so that the shim can be extracted,if you have a lathe you can just make one or I can look up the part number if you need.
Do go right ahead and do it yourself,though. Shim over bucket isn't too bad, somewhere between shim under and tappets for difficulty.
Be prepared to use up your three weeks, though, Idon't know your situation but here in little USA(Canada) shims actually have to be ORDERED!
The formula for determining replacement thickness also doesn't get it right the first time, either I don't know why(anyone?).Don't worry if you have to take a few stabs at it.
 
Having built HUNDREDS of VOLKSWAGEN engines I can assure anyone that exhaust valves DO stretch. Usually this culminates in a (dropped) valve head, holes in pistons, ruined heads. Valves will wear the seat and valve face which causes tight valves. ANY significant change in clearance needs ATTENTION.
