I've added a Uni filter and drilled the exhaust. The stock size is 128. I tried to drill it out with the tiniest bit I could find, now it's running too rich. Either I drilled it too big or just screwed up the orifice. It's bogging down really bad at WOT, but runs like a striped ape until I go wide open. It would be nice to replace a jet instead of having to buy a new carb, since I'd also have to buy a new intake since the stock intake is for a bolt on carb.
