    4-1 exhaust and open air filters 78 gs750

    Looking at adding four into one exhaust and have open air filters already but haven't ran. When I get the exhaust any suggestions on what to up jet my bike too. Anyone know what's a good combo to put in for this, fairly new to these bike and don't want to screw up the motor by running her to lean...

    get a dynojet stage 3 kit and save yourself a lot of hassle.

    Just remember, an opinion without 3.14 is just an onion!

      Use the search function, there are plenty of threads on jetting '78 750 w/pods & 4-1.
      BTW, Dynojet do not make a stage 3 kit for that bike.

        Get some real pods like K&N or Ape. Don't even waste your time with cheap Emgo junk pods.

          right on, I just bought k&n's and they look a lot better than the cheapo's I picked up off ebay......was wondering by chance if a certain size main and pilot would be in order, to make this thing run smoothly, I was thinking about just buying a big kit and doing some plug chops.. didn't know if there was a good combo to put in right off the bat

            Per my friend Eric, start out with 117.5 main jets and adjust the fuel screws out one full turn and adjust air screws and main jetting after riding and check your plugs. (Based on your riding being between Sea level and 5,000 feet)
