ryana1987 Posted December 17, 2010 Report Share Posted December 17, 2010 I got my banshee 3 months ago and have done some of mods like fatty's and power core 2's... the shaved head, vforce3 reeds, twist throttle, .60 oversized, jets, idlescrews and tors removal were done right before i got it. I put a new magneto, pickup and ignition coil, voltage reg, spark plugs, stator and adjuster plate so spark is STRONG. i mix 40:1.......but when its cold ill pull the choke and kick 3 times....it fires up...runs about 5 seconds and dies, so the kicking begins(and yes i shake the wheeler before i turn the gas on)after about 20 mins of kicking like a mad ninja it will finally start and runs great. and if it sits for more then 30 mins i have to kick for 20 mins again, and even with the idle screws turned to the max it still wont idle.. i am thinking carbs? this is my first dual carb atv plz help Quote Link to comment Share on other sites More sharing options...
fastquad02blaster Posted December 17, 2010 Report Share Posted December 17, 2010 It could be a number of things. It could be flooding on that initial start up. Are you kicking it for 20 mins with the choke on or off? It idles fine once warmed up? Quote Link to comment Share on other sites More sharing options...
ryana1987 Posted December 28, 2010 Author Report Share Posted December 28, 2010 i shake it all around to mix the gas up....then turn the gas on, pull the choke give it about 3 kicks and it fires right up and runs about 5 seconds and dies no matter what i do with the choke or how much throttle i give it and then i kick for 20 mins i get an acasional backfire though....i've even taken out the plugs and checked to see if it was flooded with a mini torch but it wasen't flooded???. once it warms up it runs great but it has never idled ....idle screws are out and dies when you let off thanks and sorry for the late reply i didn't expect to get a reply back so soon haha Quote Link to comment Share on other sites More sharing options...

ryana1987 Posted December 28, 2010 Author Report Share Posted December 28, 2010 what pilot jets are in it? i have no idea, .the guy only said it had new jets put in...oh and the colder the weather the longer it takes to get going. i don't know what size the domes are either but probably stock because its the stock head. also should my engine have a knock at low rpm and then go away after the throttle goes up? i use pump gas 40:1.....

Jereme6655 Posted December 28, 2010 Report Share Posted December 28, 2010 what other mods are done? any? you should be running MINIMUM 91 octane if not higher......you may want to contact him again and see what fuel he was running in it.... Also pull the pilots out and look at the marking on it....25 is stock and the fatties along with most aftermarket pipes require a larger pilot jet such as a 27.5 Running a 25 pilot and aftermarket pipes will make it hard to start alone.....not counting the cold weather. Jump those pilots up one size and it'll also help cold weather starting Quote Link to comment Share on other sites More sharing options...

Jump those pilots up one size and it'll also help cold weather starting the air filter covers off of coarse...but other then the tors system removed, .60 oversized pistons, vforce3 reeds, shaved head, fmf fatty and power core 2's there is nothing else. I always ran 87 octane because he did and im not sure what size the pilot is inside...will that help the idle also? im new to this 2 stroke carb stuff where the jet sizes are very important, thanks!

Jereme6655 Posted December 29, 2010 Report Share Posted December 29, 2010 yes it will help it idle SOME. 2-strokes live and die with jetting. its not that prevelant on 4-pokes because they have a serperate oil system.....2-strokes die because of lack of enough lube to make things stay in shape. There is a thread in the jetting board that tells how to do a plug chop....id recommend that. And remember that no matter what.....when the temperature drops or rises (depending what your jetted at) you need to change your jet sizes!!!!!
