db25 Posted July 14, 2012 Report Share Posted July 14, 2012 I have a stock banshee, it only has a k&n air filter on it and I'm running 32:1on my oil mix I just recently bought a set of fmf gold series sst pipes with power core 2 silencers. I'm wanting to put them on but I need some advice on the jetting. My home area elevation is around 800ft. but I occasionally ride in 1500ft. But that's not very often. So my question is what do I need to change the jets to.? Should I run with the airbox off. what about the air to fuel screw.? Where should I turn it to.? Do I just have to change the main jet.? I don't know guys any help would be great, I don't want to take it to the shop to have it done and pay way to much.. That's for the advice Quote Link to comment Share on other sites More sharing options...

Jereme6655 Posted July 16, 2012 Report Share Posted July 16, 2012 Read up on how to do a plug chop. Then run with some 27.5 pilots n there and around a 260-270 main (this is why you need to know how to do a plug chop to check) Quote Link to comment Share on other sites More sharing options...
db25 Posted July 17, 2012 Author Report Share Posted July 17, 2012 I've heard about plug chops but I'm not exactly sure on them but I just want a good starting point to work with. What about the air to fuel screw..? Should I just leave it alone.? Quote Link to comment Share on other sites More sharing options...

Jereme6655 Posted July 18, 2012 Report Share Posted July 18, 2012 Put in 27.5 pilots. Set air screws to 1.5-2 from seated. Then put in 270 mains. Warm the bike up on the plugs that you have in it. Shut the bike down....then put brand new plugs in. Fire the bike up and immediately run the bike full throttle from 1st gear through the top of 6th.....when you get it up there pull the clutch in and shut the motor down and cost to a stop. Then reinstall your original plugs and ride home. Take a hacksaw and cut the threads off around the plug where the threads meet the base of the plug. Then you will look at the porcelain base of the plug....it should be a milk chocolate brown about the thickness of a dime. If its lighter than milk chocolate or grey then you are too lean on the mains. If it is dark brown then it is too rich. Jereme Quote Link to comment Share on other sites More sharing options...
db25 Posted July 18, 2012 Author Report Share Posted July 18, 2012 Okay I'll give that a shot but what about the needle clip position.. What do you recommended on that.. Quote Link to comment Share on other sites More sharing options...
db25 Posted July 20, 2012 Author Report Share Posted July 20, 2012 Needle clip position... Any advice..? Quote Link to comment Share on other sites More sharing options...
db25 Posted July 22, 2012 Author Report Share Posted July 22, 2012 Okay I installed 270 Mains, pilot is 25, the local shop didn't have any 27.5 so I figured I would change that later. carbs are synced, needle clip is in the middle.. I'm guessing that's the stock position but idk. Bike starts great but It won't idle at all. Runs awesome other than that. when I change to the 27.5 will that fix the idle or should I change my needle position.. Any help would be great, thanks Quote Link to comment Share on other sites More sharing options...

db25 Posted July 31, 2012 Author Report Share Posted July 31, 2012 Tors is removed. To start it yes I do give it a little throttle, choke if its sit awhile. The air to fuel screws are two full turns out. I messed with them some while it was running and I just couldn't get it to idle really at all, it might sputter for a couple seconds but that's it then it would die.
