        hi there,

        I am new to this forum and starting (as a hobby) to restoring GS 750 - 850 & 1000 bikes.
        At the moment i have 3 750's, 3 850's and 1 1000 all around '78 - '81.
        Some bikes are messed with and i want to transform them in to caferacers.

        Mi first question is; How to now what kind of jets size to use when working with say: 4 in 1 exhaust? or with K&N pods instead of traditional airbox? and the relationship fieul/air ?

        grts, ice

            I found all the information for my 1977 Suzuki GS 7750 carb on this thread and I appreciate the time people take to share that info. I could not find what the fuel screw setting should be. The screw on the bottom of the carbs on the motor side. Does anyone have a ball park range for these? I'm assuming all bikes are a little different that's why they don't give a specific spec. I doubt the number of turns is largely different between bikes though. I can't see one bike being at 1 turn and the other at 3.
            Thanks!

                Look on this page on Basscliff's site Dennis,



                Main Jet is a 112.5 and Pilot Jet is a 42.5, of course, I'm only reading the guide and others may know better

                        What is the difference between a needle jet and a jet needle? I saw the specs that Bass Cliff put up for an 850. ( factory manual uploaded pic ) and there is specs for both. I am familiar with needle jet, but jet needle?

                        Comment


                          One is a jet meant to work with a needle. The other's a needle meant to work with a jet.

                            Hi,
                            I´m looking for carb specs for a ´79 gs500e. It´s bought in Sweden, the title says it´s a ´80 - frame # is: gs500e-104630 (engine # 104622). The carbs are mikuni VM type (22mm? - how/where do I measure the bore?) stamped 470-50. I´ve checked the spec sheet (v1.3) - but the only 500 there is with a CV (BS32SS) type carb. (Besides, I think it might just be a misprint - that it´s actually just another 550...) There is a 550 with a VM22SS carb listed, however, but it´s still a 550. I have the Haynes manual for the 550/750s, which works fine for the most part - but my bike is a 500, so it should probably have different jets... or? Does anyone have an idea where I can find these specs? OR should I just cross my fingers and buy new jets according to the specs for the ´79 550, ? Maybe someone has an original Suzuki repair manual for the ´79 GS500E lying around - or know where to get one??? Please help, cause I´m kinda stuck here!
