I just bought a mikuni TM carb off of a 86' TRX 250R. I am going to run it on my 85' ATC 250R. My ATC only has a dg pipe uni air filter and boysen reeds. What size jets (main and pilot) should I go with? I am new to mikuni carbs so I don't know much about their jet sizing. I just want a size to start from for when I order a few jets for it.

hmm. if i remember correctly, my 300r with the mikuni was rich with a 320 main, so somewhere in there might be a decent starting point.

It has a 350 main in it now and is rich. Also I can't get the thing to idle.
