well im sure someone here could tell you the stock jet size, but noone can tell you what jets to use and just guessing wouldnt be a very bright idea...it depends on your elevation and of course the mods u listed, the only thing i can tell ya is heres a link to a excellent post on jetting... http://www.3wheelerworldforums.com/showthread.php?t=55086

If your trying to jet it based on one of our posts, goos luck. Read up on jetting and start from scratch, there isn't any other way....
