we have a 05 banshee, 22mm domes, fmf pipes no air box, 280 mains, installed vitos pistions, and cpi drag pipes, now its hard to start and wont idle unless chokes out, this should have been a power gain but dosnt run like it should, bike ran fine, until work was done, it use to start first kick, please help

 

You are getting to much air, for the amount of fuel you have. When you put the coke on, it cuts down the amount of air, and that gets the correct air:fuel ratio back.....

Sounds like a classis case of a clogged idle (pilot/slow) jet. Modern fuels, gum these up real fast when the gas sits around and gets old. Clean the carb, and pay particular attention to the idle jet.

Also, might be a leak in the air intake system somewhere. Be sure the air filter is ok (the Banshee has a stupid air filter on it, just like my Warrior did!), and you don't have a crack or leak in the intake boot.

 

As recon said sounds like typical time to tear down your carb and give'r a good cleaning. Bad thing is, after all that has been done too it chances of it being something other than gummed up carb increases.

 

thanks recon i will check it today, your probly right, i tried yesterday to adjust idle and nothing changed, im also going to try to put the fmf knarlys back on 2, those cpi drag pipes are way 2 loud

 

Did you change pipes without a rejet??? If not, might be the problem right there???

 

That's what I was thinking. Those Drag pipes require much larger jet than other aftermarket pipes. I want to say my bro was running 260's with toomy's t5s but, didnt' have near the mods you have.

 

Hope you aren't way lean....and burn up your pistons!

 

shouldnt have burnt pistion ive only rode it done the road and back couple of minutes, still though with 280s it should run alright i hope anyway it will run like a scalded dog on top end, just low rpm and idleing is were it sucks, could the carbs be too small for those loud *** drag pipes

 

im going to tear into carbs this evening, i wish those carbs were like my yfz
