    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.

Hello all,

It has been a long cold winter and I am ready to ride again. I changed my email and so had to change usernames, I used to be scottjm. My question is this. Last winter I dipped and cleaned my carbs replacing all o-rings and completely followed the carb clean up info posted on this website. I did order four new carb kits and replaced everything including the main jets. The originals were 112, the new ones were 112.5, would this slight increase in size make my bike run rich and carbon up the plugs? The bike is a 1980 GS750E.

Thanks

Scott
 
Thanks Jon, I was hoping it was that simple :( .. I will check float height next, oh by the way, does anyone have a simple method for bending the float tab, and what is the best way to do it?

Re: Main jet size from 112 to 112.5

Jets come in increments of 2.5 ie. 105, 107.5,110, 112.5, 115 etc.

That's what I thought too, I'd never heard of a 112 jet size. Just figured I had missed it because of my sheltered life.
 
Fellas.....,

Ooops....guess its kinda funny for me to say your right...DUH.... The jets I replaced were a little varnished and junked up, I only saw the 112, after I read Earls post I went to my garage and did the finger smudge removal technique on the old jet and noticed it was indeed a 112.5.

Sorry for the confusion, I should be sorry for being confused...

I also took my carbs off to check float height on each and noticed that the number one carb did not 'spring' back up when I pushed the float down slightly..hmmm.. I put the original back in and it works fine, hopefully this will help out on my rich condition I had experienced all last year!!

Thanks for putting up with me... :)
