    2001 GP1200R Carbs

    Hey everyone,

    Its nice to be on the forum! I have a 2001 yamaha gp1200r that i burnt up the 1st and 3rd cylinder in. I am currently in the process of rebuilding the carbs and have a question about jetting with a drilled return orifice. If i drill the return orifice and put the restrictor jet inline can i still use the 110 pilot, 120 main, 1.5 n/s & 95 g spring, without the acc pump, with premix and after market f/a's? You thoughts on this are greatly appreciated, thank you!

    Rich is selling crap now?
    I don't believe it!

    (it was funny when the above had the word "crap" before the edit to "stuff")

    So my next question is, if i am running these mods above with out the free flow pipe, what should I do with the reed stuffers? I have done my reading on reeds 101 but i cant seem to figure out if i need new reeds. Thanks again for the knowledge!
