    Preparing BS32 carbs (pre - tunning) for gs 550 / 650 swap with ported head

    Hello everybody!
    My last choice for my future gs 650 / 550 base swap is BS32 carbs. I also have BS 34 ones but they will be too big for this motor.

    I have to buy some parts for them. I do not want also to buy parts for tunning that I won't be able to use...
    The bs 32 that I got are gs 850 carbs. (Do not matter about spacing, I'll fix that with aluminium boots)
    What tunning configuration, for start should advise me?
    - main jets?
    - needle (size and height)
    - idle jet?
    - air jet?
    - about float height I'll keep it as stock.

    Note that My gs 650 head is totally ported, with a compression ratio 's aim to 10:1 as a minimum (gsxr 33mm diameter exhaust with aligned ports, 32mm boots, aligned to the intake ports, and +1mm diameter valves)

    thanks!
Working...
