    I only see two different weight pop off springs, is that all there is or do you have a source for pop off springs? How about jet blocks??
    Chris I get my Keihin jets from Atlantic Jet Sports. But yea a few places have them. The actual Keihin rebuild kits come with springs. Beyond that, I have never had to change a needle and seat yet.

    Also to be clear, the good carbs were on 94 and 95 small pin ss xis and xirs. The rest of the dual 750 Keihins are not all good, the later (38mm?) ones off the big pin were smaller and I would dump in the trash. I did a quick check and it looks like the 96 ss xi switched to big pin / 12 bolt intake / smaller 2 jet Keihins.

    So for those of you out there who are interested in Keihins, be careful which ones you get. You want the dual 40mm Keihin CDK2s off the original dual carb small pins for sit downs. They came on the lime green head engines, but may not be exclusive to those engines. Also of note the 95 sxi came with different, 2 jet versions of the original good 40mm Keihin CDK2s. That is a different topic entirely.
