We just got a 340 kit installed in one of our bikes and we can't seem to get the thing running. Besides the kit, it has all the free upgrades, Uni filter, and the stage 2 jet kit from Dynojet. We set the bike up per the spec sheet that was included in the jet kit, but it keeps fouling the plug and won't hit a lick. He's getting a high-flow header pipe tomorrow, so I just told him to wait until it's installed before we waste a bunch of time troubleshooting. btw - the bike was running when it came home from the shop. Is the suggested main OK for this combination? It seems to be running REALLY rich, but some fiddling with the fuel screw really didn't help either. Maybe just hold out until the header pipe is installed and go from there? I'm guessing that it makes a big difference in the jetting.
