wrreilly Posted June 27, 2013 Report Share Posted June 27, 2013 Hi everyone, can someone tell me a little about the air Jets on stock Mikuni Carbs? I was cleaning out my carbs and rejetting this evening and noticed a jet in the lower intake side of my carb I have never previously seen. I took this jet out and was able to make out "1.6" but realized that only my left hand carb had this jet. After some research and looking at a parts fiche, this is what is known as an air jet. Basically I understand what it does but what I don't understand is why only 1 carb would have one. Is this unusual?? Thanks in advance, Bill Quote Link to comment Share on other sites More sharing options...
Larry's Shee Posted June 27, 2013 Report Share Posted June 27, 2013 Bet it has something to do with choke circut Quote Link to comment Share on other sites More sharing options...
tdod101 Posted June 27, 2013 Report Share Posted June 27, 2013 I was confused when I was trying to figure it out as well, it's actually an "air correction jet" same shit I suppose but both carbs are supposed to have them Quote Link to comment Share on other sites More sharing options...

wrreilly Posted June 29, 2013 Author Report Share Posted June 29, 2013 Hi everyone, and thanks for entertaining my forum post. To: Tdod101, what is the significance of this jet? Is it like basically yet another jet to more or less micro tweek the air fuel or is it as "larry's shee" suggested and part of the choke circuit? To: 375hp banshee, I currently have 350 mains and 25 pilots but with that being said, the pilots are for too small so I have a set of 30's on the way. The 25's will idle the bike but with the air fuel screws turned all the way in so I need to rejet.... Quote Link to comment Share on other sites More sharing options...
tdod101 Posted July 1, 2013 Report Share Posted July 1, 2013 To be honest I don't really know what it does, I called mikuni and asked, what it was, all I know is that you need it Quote Link to comment Share on other sites More sharing options...
wrreilly Posted July 3, 2013 Author Report Share Posted July 3, 2013 Thanks again everyone for responding! I fixed my carbs and they do exactly what they should do now. Just for kicks I also put 30 pilots in and really should also reduce my mains down to 320 or so. It's a bit rich and likes to foul plugs but I suppose fouled plugs are always better than fried pistons huh...
