Monsterenergybanshee2014 Posted July 24, 2014 Report Share Posted July 24, 2014 Hey Guys I was wondering if I could get a little input about the jetting I am running on my banshee. I have the following done to her: Stock mikuni carbs with Stock Bore Stroke on engine compression is 120 per cyl 280 main jets 25 pilots I am 882ft above sea level I also have timing plate mode +4 and FMF fatty and powercore pipes and K&N uni pods and outerwear covers My question is do you think I should bump up my pilot jet to a 27.5 and or 30 pilot jet she runs pretty nice fires first kick but I have 8 months into rebuilding an old 91 J arm frame and I really want to be sure I don't lean her out too much a blow my motor. Any thoughts? Quote Link to comment Share on other sites More sharing options...
BUILDER Posted July 24, 2014 Report Share Posted July 24, 2014 Well changing you pilot is not going to affect anything other than the bottom end. If it runs good and has for this long I would say you are pretty damn safe. If you were going to blow it up would have already happened 1 Quote Link to comment Share on other sites More sharing options...
wayne_smith97 Posted July 25, 2014 Report Share Posted July 25, 2014 I have the same setup but mine liked 27.5 pilots and 300 mains. What are you plugs telling you? Quote Link to comment Share on other sites More sharing options...
Monsterenergybanshee2014 Posted July 25, 2014 Author Report Share Posted July 25, 2014 I have only rode this twice since it got rebuilt and plugs looked a little on the lean side when I did a plug chop. That's why I thought I should ask she runs idles strong has no break up in power but I just thought she might be just a little too lean . I tried running a 300 main jet and she didn't like that so I thought maybe bumping up my pilot jet would help me so i guess what the hell i have had this machine apart a million times im gonna buy some 27.5 pilot and just see how it turns out. Thanks Quote Link to comment Share on other sites More sharing options...
wayne_smith97 Posted July 25, 2014 Report Share Posted July 25, 2014 If your plug looks lean in a wot throttle fifth gear plug chop then changing your pilot isn't going to help Quote Link to comment Share on other sites More sharing options...
