    GP1200 Carb Rebuild

    I bought genuine Mikuni carb rebuild kits and tore down my carbs. My internals on the pump side of the carb match the SBN 38 parts, not the SBN 44 on the diagram included with the kit. Is this a Yamaha quick or do I have some kind of rigged carbs from the previous owner? I tried looking for previous posts about this but couldn't find any. Could someone tell me if this is normal and/or include the link to a previous post if this has already been discussed on this site?

    Thank you,

    Jason

    Explain what you mean. The 44mm should have the o-ring style seals on the pump side does yours?

    Bill,

    I just looked at the SBN manual and the exploded diagram actually denotes that late model 44's use the same components as the 38 on the pump side. Mikuni should change the diagram that comes with the kits to include this notation as well. All is OK now.

    It says 38 and late 44. the easiest thing to do is just match up components

    Yes the actual Mikuni SBN manual says "sbn 38 and late model 44's" for the pump parts, but the piece of paper that I got with my rebuild kits doesn't notate that, it just lists the internals in my current carbs as components for the 38. I should've just looked at the manual in the first place. Thank you for offering to help me though.
