    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.

BS needle and seat assembly

Are there alternate sources for the OEM Mikuni needle and seat for the CV carbs? They are $60 each from Suzuki, I don't think that is realistic. I see Sudco has a wide variety but I don't know which one to get. Anyone have a part number or a way to decipher what the options are (2.0. 2.4, etc)? No way I am using K&L.
 
Also, genuine Mikuni parts will have their ?square in square? emblem.

JetsRUs has a chart that makes it easy to figure out which type of needle valve assembly you have.
http://jetsrus.com/needle_valve_float_bowl_gasket/needle_valve_and_float_bowl_gasket_mikuni.html

Your existing needle valve assembles will have the flow rate # (2.0, etc.) stamped on them.
Shop manual also should have the flow rate info.


You can order from them or maybe save a few more $$ via eBay.

Thank you, that helped a lot. I found the 2.0 on the bottom where the filter snaps on after I polished it a bit, also the hole measures 2.0 mm. The jetsRus ones have a Sudco part number, not sure if they are genuine or not. Going with these instead https://www.amazon.com/Mikuni-Needle-ans-Seat-Valves/dp/B000TG1EE6 . Much better price than $60. For reference the correct part number is N149.040 2.0
