    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...

    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.

2 tings: Valve adjust BARELY out and I still have a cold pipe...

Hey all,
I just completed my first valve adjustment. I just had to leave the cylinder one exhaust valve slightly out of spec because I didn't have the right size shim. It's a tight squeezed .09mm (79 GS850 btw) and I figure this probably isn't a big deal but should I immediately order the right size (2.75mm) and swap it out? Or is it ok for a while?

My second question is about my cold pipe on cylinder four. All the other pipes warm up evenly and quickly but four takes about twice as long. I've swapped plugs and wires from cyl. one but nothing changed. The plug on four is kind of red near the tip and a bit of red on the ceramic. I assume this is fuel related? I've done the timing adjustment and it's spot on. The airbox has also had a thorough sealing and clean filter. I've basically done everything to this bike before removing the carbs for a rebuild which I've never done. My next move was to replace the intake seals and maybe boots.

I also still have blue pipes on all but cyl. four... Thanks for any advice...

Synchronize the carbs. But first get that valve clearance right. I would clean the carbs anyway. Check Here
 
I had this happen right after I changed needle valve seats and o-rings.Turned out to be a piece of crud stuck to the pickup tube in the carb bowl.Picked it off and has ran fine ever since.

Yeah, I guess I'll go ahead and buy a Carbtune. I've come this far I might as well get her as perfect as I can. Thanks for the advice. It's all been on my list but I guess I just wanted to make sure I was going in the right order. The other thing is the bike is getting horrendous gas mileage and I've already done the Seafoam thing. Carb rebuild it is...
