A couple questions....Is the imulsion tube something that wears out, or was this replacement an aftermarket upgrade?
I've got a '92 3VD, and the carbs are starting to idle rough. I cleaned the pilot jets and it got (somewhat) better, but it's still popping and spitting at idle.
Will replacing the emulsion tubes restore performance, or is this just a precautionary thing? I've owned the bike for a few years now, but I'm just now getting to do some maintainence on it.
Also, what is the "official" name of the part on the microfiche? Part # would really help.

Any info on what to replace/adjust would help as well.
Thanks!

Hi Randy,
They do get called 'Needle Jets'
microfiche 353GM-14141-94-00 . . NOZZLE, MAIN . . . . .

If your gonna change them, you may want to change the Jet Needles also !
microfiche 4DT-1490J-00-00 . . NEEDLE SET . . .

I did mine using this amazing pictoral....YOU CAN'T REALLY GO WRONG !

Before you spend all yer Dollars, try a simple carb balance/synchronisation. Its AMAZING what a difference it can make. Mine was still lumpy after replacing jets & tubes but a carb sync sorted it out !
