    DO NOT SIGN UP USING hotmail, outlook, gmx, sbcglobal, att, bellsouth or email.com. They delete our forum signup emails.

    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.

Here's a macro image of the fuel screws where I tried to focus on their tips.

The order from L to R is carbs 1 to 4.

It may be beneficial to download the image and zoom with your software.

Let me know what you think. Thanks.

From what I see it looks like all 4 are different lengths and all 4 have been " sharpened " at some point. I wouldnt use them if they were going in any of my bikes. But thats my opinion. New ones arent all that expensive and youll know with confidence they are functioning correctly.

Thanks Chuck. I think you're right. There's a little fisheye effect from the camera, but the screws are all different, and those grinding marks are not up to Mikuni surface finish standards. I'll get new fuel screws.

Meanwhile, I've got all the slides out of the bodies to get needle clip position, and the four slides were not synchronized very well. The highest slide was about 30 thou higher than the lowest slide. I think with that old drill bit technique I can get them within 2 or 3 thou.

Just a bit of follow up with a macro of the Suzy's VM carb air screws.

Which appear to be unmolested, but perhaps sharper eyes will offer the continued good and experienced advice.

Thanks guys.........

K&L makes the fuel screws. I bought a set to use the springs as they were missing from my carbs. Got mine from Z1 but any K&L dealer should have them. Never compared the new ones to the OEM ones so can't really comment on quality.

Thanks hannibal. The K&L catalogue does certainly have many carb parts and seems like a very good source.
