    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.

Gs250 needle jets

Forum Newbie
Guys and girls I have a question regarding the needle jets in the 250 and 400 twins.
in the Haynes manual for the fuel system spec, the left and right carburettor needle jets are listed as different numbers. I can't for the life of me think of a reason why they would need to be different in any way.
For example the 400 is listed as P-1 for left side and P-2 for right side
has anyone know of the reason?

Regards
Lucky Pete
 
I don't think it matters at all. I stripped down my 250's carbs last summer. I'm not sure which jets came from which carb. But it runs great. So I wouldn't worry about it. Probably labeled in the book that way to indicate that there are two jets total (one per carb).

By the way, if you know where to get new needles for the 250 that would be great, mine are getting wore down.
