    A Special Note about Email accounts!
    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.

Jetting for mufflers

Well Keith. Mostly I took the day off today. The heat just got turned on in the Okanagan in a serious way.

I did have a chance to ride and check the plugs. Black and sooty.

I need gages for the vacuum synking of the carb's. I like putting money into tools instead of labour costs.

Slow speeds produce the stuttering ride still. I'll do some more cleaning this week. Never removed the floats so I may have something gumming up the works.
Power band range seems to be good.

You've given me lots to do. I'll be back.

Thanks again.
 
OK. Like I said before, you need clean/synched carbs to get accurate plug reads and good performance.
You also have to tell us what throttle positions caused the plug colors/reads. Three separate jetting circuits here.
Black and sooty is obviously rich, or a weak sparking problem. Since it sounds like you need to service the carbs, do that as you've planned. Test, and we'll go from there.
