    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.

Extra Part?

OK, so I'm finally doing my carb re-build to eliminate those as the cause of my power loss on cylinder 1. It was either this or start replacing valve oil seals, and this seems the easier job.

So last night I got the carbs off the bike and got them seperated - no thanks to some semi-stripped phillips screws on the lower gang plate (note to self - stop by Ace Hardware on the way home).

The extra part in question is a washer that stayed pinched between the spring-loaded brass plunger and the sync adjusting screw on the #3 carb throttle lever. Looks like the PO or someone used this washer as a shim (to get the sync right?), but I wanted to make sure it didn't belong there. It's only on one carb - if it weren't #3 I might not even have asked. I don't see it in any schematics or pics in the shop manual.

I'm also open to any theories on what the person who did this was trying to accomplish - why a shim when there's an adjustment screw?

I'll take a pic tonight if that'll help - didn't have the camera handy last night.
 
I quess I'de need a picture for that one? Not sure without seeing the rack as to why it would be there.
 
Maybe they replaced the screw with one with a head that was too small & the spring was coming past the head....

Maybe it's an aftermarket spring that's bigger diameter & going past the stock screw??

I likely have a spare somewhere if you need one.

That's where the throttle plates hook together from the seperated carbs. Lose the washer and see if you can get a good bench sync.

I think the spring is just right - removing the washer doesn't look to effect it. I'll take a closer look at that, and if everything's in order...
