    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.

450FREAK

Guest
I own a 81 450L, and was hoping someone could give me a little knowledge on carbs. what model they are, if there is jet kits still available and if i put a mac exhaust on and pods, what jets to use. thanks for any imput
 
Being an 81, I would think that you're likely using BS32SS carbs. I may be wrong, as ive never really investigated the set up of a 450, but generally after 80, i do believe just about every bike on the road was using some form of constant velocity carburetors. And the BS32SS were used on everything GS that I am aware of from 750 down. Yes there are jet kits still available, thru DynoJet. If you're simply switching to a aftermarket pipe, and NOT changing your intake (still using the stock airbox) then you'll likely need only the Stage One jet kit. However, I would investigate with DynoJet and MAC on their suggestions. Some pipes suggest that rejet is not necessary.
 
WOW! That big? Well i guess that makes sense, two cylinders with a larger bore than that of a four would require more fuel?
 
I just had a feeling

Plan on doing some serious rejetting, or check Dynojet for a kit.

the 81 450L uses mikuni BS34SS carbs

second that, BS34SS, prob. series 44100 or similar, check main jets to confirm that they are mikuni, not keihin (different outside diameter)

my -81 (ex) use Keihin jets in the mikuni carb - can be confusing.

Yeah that sounds like it could be very confusing, thanks for the heads up, i'll make sure. Waiting on responce from Dynojet just can't wait, wanted to see if any one here might know. Thanks
