    Aftermarket Carbs

    So I posted the pics of the "mysterious" carbs that I had got with my engine purchase a while back. I measured them out and they had 48mm butterflies and we ended up coming to the conclusion that they were Buckshot Magnums...

    I found this thread on another site, not to mention the name but here is the write-up:

    F.S 48mm Full Spectrum carburetors
    I picked these up in the fall when I was planning to build a Blaster to race this season. I changed my mind and decided not to build a blaster and rebuild my HX. I have never run these carbs so I really do not know how they hit or anything. All the screws are working, I removed the jets to make sure none were stuck or anything, the needle and seat look good (1. no idea what spring is in there. Butterflies are not perfect but look like they would be ok to me, or you can order new ones directly from Full Spectrum. These are not the most recent version of Full Specs I have no idea what the differences are between these and the current model. These have the built in fuel pump or you can run them on an auxiliary pump. I really canít tell you much more about these other then look at the pictures.
    $500 and they are yours.

    And here's a pic of mine, they are identical.

    Booster looks like Full Spectrum. They are probably old model. Do a google search and get contact info. I am sure if they are still in business Ed will help you out on setup. These were the best carbs back in the day.

    Here's what Ed as Full Spectrum had to say about the carbs:

    Your photos are of the Red Mikuni carburetors that originally sent to us by
    Team Butch. They had asked us to make certain carburetor sets for them
    out of those Red painted Mikuni bodies. Rob, by measuring the carburetor bore beneath the throttle plates you will be able to determine the true bore size. From your photos the throttle plates seem to be in good shape. That is good. The main booster system for the GP1200 have been redesigned to what we now offer for the GPR1200's both limited and Superstock engines. I am wondering if that carburetor set was initially made for a triple 1200 or was this set of carbs. supplied from 46 or 48mm single carbs. and assembled by Team Butch for one of their engine kits? Please let me know what you can find out. This information can help me determine what you will need.
    Sincerely,
    Ed Brazina

    Anyone heard of Team Butch?

    Team Butch was a late 90s race team. Long gone. A couple of pro riders and Pro-Am women. They were a 2nd tier team back in the day.
