    what exactly does the main jet say DJ 125.5 or does it have a little square with a little square in that with 125.5 next to it.

    so did you ride the bike after you cleaned it and is that when your brother was soak in rich gas vapor? what do the plugs look like?

      It could be just a matter of lowering the float level?. 125 jet is on the rich side

        the main jet only says 125.5 the local useless suzuki dealer said its the size.

        The ride was after I cleaned it and replaced the fuel needles, and set them correctly.

        The plugs are a moist black in colour!

        thanks!

          Ahh, an Ozzie, I'm inclined to be a bit more understanding. :-) For a four into one, and going back to stock airbox and filter, go with mikuni main jet 115. Stock pilots will be fine. Set the fuel pilot screw to 1 1/4 out. Airscrew about 1 3/4 to 2 turns out. Plugs should burn about a light tan. You may have to raise the needle one notch, from stock. Been there, done that.

            Upon seeing that it was good, he went out again on his ZX14! But just a little bit faster!

              So K&N pod filters are crap for the street? The stock airbox will increase the power? As previously mentioned, less fuel and less air flowing through the engine will increase the power? You and your retired racer have it a little backwards. If he tuned the bikes he rode, I don't think he did much winning. And he wants to bet? What a joke.
              The only reason you apologized was so you can get some free info, not because you meant it.
              If you hate forums, why are you still here? Visit a jetting site. You and your retired racer might learn some basics.
              As you say, quit wasting forum time and space. :P

                What a bunch of nasty, vengefull and sarcastic SOBs hang out on these forums.
                I guess sometimes we must break our own rule of no messing around on the tech forum.

                nice job fellas. I really enjoy watching others do the necessary work.

                    My '77 GS750DB had the stock airbox (until last night) and runs with a lash-up 4 into 1 exhaust using the silencer off a Kawasaki 750 of some sort. Main jets are 100 and the plugs are the perfect tan colour. So unless you have some really free flowing exhaust you may be aswell to start with these and see what colour your plugs go.

                    As an aside, last night I junked the standard airbox and have fitted pod filters, and am waiting for delivery of a V&H 4-1 exhaust. So I'm going to have all the fun of trying to get the jetting right. I've been recommended to start with 127.5's and work from there.
