03banshee88 Posted July 27, 2015 Report Share Posted July 27, 2015 So I got this 03 banshee has Athena 392cc big bore trinity 2 to 1 carb set up and full fmf powercore pipes with a modded lid air box. Now it starts right up everytime but it has like no power on low rpms until I floor it in first it bogs hits power band then runs great in high rpms. Not really sure where I should start Quote Link to comment Share on other sites More sharing options...

03banshee88 Posted August 1, 2015 Author Report Share Posted August 1, 2015 So it has a 170 main jet and a 55 pilot jet and it seems to have stock reeds still in it as well. Doesn't that jetting seem kind of low for it being a big bore with all the other add ons Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
