I know this has probably been asked a jillion times, but with my limited research I didn't really find a lot. BTW, I'm more familier with Vtwins and have jetted a few from "package jet kits" such as cobra and dynojet.
What I have done is taken a saw to a perfectly fine tuned running completely stock 1982 XS400 Heratige Special. I just completely rebuilt these carbs and synchronized them to factory specs and the bike runs like a champ for the past 200 miles with the stock exhaust. Tonight I hacked the mufflers and installed a set of Emgo shorty mufflers onto the headers. Fired up the bike and she stumbles pretty bad, but once warmed up it smooths out over 3,000rpm, but it won't idle at all....... Give me some advice? Will simply adjusting the idle mixture screws clear this up? Or do I need larger pilot jets? Do you think I'm running lean or rich????????
