    Sbn44 for 650sx help needed!

    Iím new to the forum and stand up world but want to improve my stock 650sx. Iíve been told the sbn44 should wake the ski right up. From a little research it seems I will need a few more parts to make this carb work with my ski. Anyone have a parts list of things I will need to make install easiest? Also any other tips and tricks to gain more performance would be great! Thanks

    Welcome to the site!!

    I have everything here in stock to do the upgrade.

    New, GENUINE Mikuni carbs (Beware of fakes / made in china copies)
    New SBN intake manifolds for Kaw 650
    New carb top adapters, and flame arrestors
    New Cable mount brackets, and multi hole throttle wheel.
    Primer kits
    Any needed gaskets, reeds, and more......

    Carbs are universal, and need to be jetted for each application. I can jet the carb for you, and sell as ready to run if you want.

    Welcome! Which carb do you have now the 28mm or 38mm? You can also very affordably dry out the stock pipe for some added punch and rpm. Is you impeller the OEM original? Gains to be had here with replacing the stock.

    John has great parts and technical advice. Dont be afraid to give him a call.
