    okay, started on the gs1150. carb suggestions..

    bike has been sitting for a few years, p.o claimed to have drained the carbs and tank....not quite all the way though.
    anywho, bike is a 1229, v&h prepped head, megacycle 255 duration cams (sorry only spec i have), kerker four into two exhaust, accel ignition, coil, wires, etc. stock carbs with friggin big dynojet mains. peering through the intake tracts, its evident someone has been busy. new base, valve and head gaskets too.encouraging!
    my question is... if i go with flatslides, 36 or 38mm?

    Nice and by the sound of it, it should cook as good as it looks.

      Bill is (was) running a 1230 with the 1150 CV's His head has SS 28.5's on intake and light porting. Gas mileage was over 30 but about 15-20% less than me with 1166 and more aggressive head port. I also have the 36mm 1150 carbs but running 145's on mains. We both have 0.340" Webcams except he is 108/108 while I'm 105/107

      So unless you want top end speed with cost as no object then go 38 RS, but 36mm RS are good for mid range but if you are on it alot the mileage will suffer.

      Are you doing a restoration project of some kind on a GS? Let everyone see what you are doing by posting the details here.


      OK
      I think I'm done with the jetting
      Mikuni BS36SS carbs
      47.5 pilot jet
      Idle mixture screws out 3-3.5 turns
      150 main jet 1&4
      152.5 main jet 2&3
      Dynojet Jet needle third notch from bottom
      Pulls great bottom-top
      Idles great with the 47.5 pilot jets
      I tried this setup with the Jet Needle 3.5 notches from bottom but ran too hot for my liking. The three up gave me better color on the plugs and it ran cooler.
      The plugs look perfect
      Also ask GS1150streetracer he has a 1230 in an 1100. Siggy says he is running 36mm RS

        gas mileage is not a concern as this is more or less a play bike.
        i can't find any jetting# on any of the mains in the cv's but man they are BIG!
        so 36's or 38's should be ok?
        the more i clean these cv's the more black paint is coming off. any easy way to remove all of it without completely tearing down the rack?
        picked up a 4 into one complete vance and hines with cannister for 60 bucks at mid-ohio last weekend. will probably end up installing itin the future.
        also how about sprocket gearing? what is a good combo to run with it oriented more for quarter mile than top speed?
        thanks

            Are you going to be selling the stock carbs? I might be interested.

              been running in and out of the 100 degree garage today cleaning them. but they are getting clean. do the float needle seats just pull out once you remove the little bracket held by a phillips head? they might still need a bit more love before they'll come out. could be the o-ring is swollen from solvent.

                  I'd go with at least a 38mm. That engine has to breath. G.

                    They pull out, try giving it a little twist.

                          go with whats the best price used.
                          36 RS miks are 8 second carbs..fact.
                          38-40's will work and make more up top but the 36's would be more fun from a lower RPM.
                          there is a nice looking set of 38's local to me for 300.00 thats a more than fair price.
                          if your interested i can hook you up with the guy if he still has them.
                          i get 725.00 for brand new RS series 36-38-40's.
                          34's are a little cheaper new.
                          let me know.

                              i just checked and the guy has deleted his ad.
                              300.00 was a good price in a bad economical area it seems.
                              if they pop back up for sale i'll let you know.
