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.

Jet Kit Confusion

HELP!!! I have a 1980 GS750E with 82 Heads. This motor is on a chopper frame. The air is 4 K&N filter pods with 4 into 4 straight pipes. My question is which jet kit do I use to keep from fouling out my plugs. At this time the mains are 130's and the pilot's are 45's. ( stock are 112.5's and 42's. ). This motor is very, very cold natured.(won't start in the mornings w/out help). Any help would be appreciated. Thank you..
 
I have an 80' and 81' GS750. I use a stage 3 kit and rarely foul plugs. I think my mains are 146 but I'll have to check when I get to my shop. Also, on both of the carb-racks I installed the air-jet-correctors. (I think that dynojet states that air-jet corrector installation is optional on the kits I purchased). I have never seen a dynojet kit that provides larger/different pilot jets. All three kits I have purchased use the stock pilots. Of course that does not mean that no kits provide pilots.

I suspect you have tried to lean-out the mixture using the air/fuel pilot adjustment scew. If not you can lean it out by tightening it down.......perhaps back it out only one or one-&-a-half turns. I think the kit calls for 2-2.5 turns out. That of course gets you more fuel/less air.
 
After reading my reply-post I realize that I didn't really address a major issue.

You know........if the plugs are fouling because of a rich mixture...the bike should be relatively easy to start when cold....cause a super/too-rich mixture sorta mimics what happens when the choke is engaged.
 
Thanks for you quick responce. My air/fuel scews are around 2 1/2 turns. I'll close them up when I get home from work. Thans again.
