Straightaxle Posted December 1, 2012 Report Share Posted December 1, 2012 Hi I bought my banshee a little bit back with a fmf gold series head pipe and power core2 silencers and it also had a pro flow adapter and filter but stock jets. It was running on the lean side. I ordered a fmf power up kit I didn't see it was stage 3 but found out obviously it was very rich. Was at 280 main dynojet needle on the 4th clip from the top and 1.5 out air screw with stock pilot. Very very boggy down low because it kept loading up. Plugs were soaked and black. I got more toys in the meantime and rejet so curious if I'm in the ballpark before I plug chop run it. 2000 banshee stock gearing 300ft. Fmf gold/powercore2 Pro flow adapter/ foam filter ehs airbox lid mod Shaved stock head .30 by fast +4* timing 280 mains Dynojet needles 3rd clip 30 pilots Air screw 1.5 out new br8es plus more for when I chop How does it look like I should be doing? All info is greatly appreciated. New to carb toys lol and wanted to get opinions to get close before I chop and fine dial it in Thanks Eric Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted December 1, 2012 Report Share Posted December 1, 2012 First off, don't waste your time with a plug chop. You can tune the bike simply by doing wide open throttle plug checks. I would try a 270 main and 27.5 pilot. Leave the clip in the middle of the needle. I would put the stock needles back in. There is nothing wrong with them. Once you've got your main jet correct, then adjust your air screw accordingly. Quote Link to comment Share on other sites More sharing options...
Straightaxle Posted December 1, 2012 Author Report Share Posted December 1, 2012 Oh yea I'm running I believe it was amsoil at 32:1 it says to run way less oil on the jug but someone said 32:1 is the way to go Quote Link to comment Share on other sites More sharing options...
Colby Posted December 1, 2012 Report Share Posted December 1, 2012 Oh yea I'm running I believe it was amsoil at 32:1 it says to run way less oil on the jug but someone said 32:1 is the way to go 32:1 is fine, if you change to 40:1 you are riching your air/fuel mixture ..

Straightaxle Posted December 2, 2012 Author Report Share Posted December 2, 2012 So you think a 270 will be enough fuel? The dynojet needle has 6 positions so I'm assuming that the 3rd clip on it is probably a half step leaner than stock needles on the third clip?

Straightaxle Posted December 2, 2012 Author Report Share Posted December 2, 2012 Oh and was just adding the ratio and 93 octane to tell what fuel I run in it Quote Link to comment Share on other sites More sharing options...
