    What do I need?

    I know i am going to need to rejet my carbs for the mods I am doing to my bike. BTW its a 78 GS550. I am putting pod filters and already have a Mac 4 into 1 megaphone exhaust. What do I need to get, and where would I get it from? Thanks

        Main jets:

        1 jet size for custom 4 into 2 exhaust
        2 jet sizes for 4 into 1 exhaust
        1 jet size for K&N filter (single inside airbox)
        1 jet size for drilling out the bottom of the airbox
        3 jet sizes for individual filters
        2 jet sizes for no muffler (open header)
        Add up all the jet size increases and subtract one. (Remember they go in steps of 2.5 for each jet size)

        Pilot jets:
        1 pilot jet size for every 3 main jet size increase

        so with the information from that thread, i would need to go up 4 main jet
        sizes and 1 pilot jet size for the pod filters and 4-1 exhaust?

          It's a good starting point

            bio...don't forget you'll need to raise the existing jet needles. Placing the needle clips 2 grooves lower than where they are now should be a good starting point. You must re-sinc' the carbs everytime you disturb the needles.
            And on the seventh day,after resting from all that he had done,God went for a ride on his GS!
            Upon seeing that it was good, he went out again on his ZX14! But just a little bit faster!
