03 banshee Jet question

[Rah4491]

Hi just wanted state that I am new to this forum and looking forward to learning new things from everyone hear. Ok let’s get started.

 Recently just purchased my first banshee project. I have had many of other bikes an quads but this is my first twin cylinder bike. I have 03 SE banshee which to believe is mostly stock. It’s in need of a rebuild an I believe the jetting is the cause for that since the carb has never been opened.  Previous  owner removed air box an installed a Tonney 2in1 filter. It has stock head pipes for now and has fmf slip ons for the rear. I’m at 1000ft sea level an I’m wondering what Jet sizes i should be running for the main and pilot? Plan is to keep the stock bore when I rebuild and most likely will install fmf fattys for the front later on so jet sizes for that would be good to know. I ride mostly tight trails with wet and dry dirt and the occasional sand dune trip to Oklahoma. Thanks and hope to hear great things from everyone.

first things first. Test compression to see if a rebuild is warranted.  

if so, then choose a site sponsor on here to send you cylinders to, to have them bored honed and set you up with the right pistons.  Get you some fmf headers off the BHQ facebook swap page

280 -290 jet when its warm, 25-27.5 pilot should be good. sync carbs and adjust air fuel screw accordingly 

then once you get bored with the power it makes and wanna open your check book up, decide how much you wanna spend and prepare for the power addiction to begin
