bansheerider313 Posted April 16, 2014 Report Share Posted April 16, 2014 I just bought a banshee for $500, needs carb work.it has 69.42mm pistons, trinity stage IV head, billit carb clamps, carbon fiber reeds, reed spacers, pro circuit 304 pipes and silencers, carbs off a snowmobile (not sure what size, the guys said they were off a 440), pro flow filter thing with k&n on it.the main jet is a 190 and it doesn't want to run, it will start sometimes but it goes full throttle for some reason. the carbs are mikuni.any help would be appreciated. It has 130psi in each cylinder.bought it because it was cheap. Quote Link to comment Share on other sites More sharing options...
n2otoofast4u Posted April 16, 2014 Report Share Posted April 16, 2014 Toss the carbs in the garbage and buy a set of stockers. Sent from my SCH-I545 using Tapatalk Quote Link to comment Share on other sites More sharing options...

wayne_smith97 Posted April 16, 2014 Report Share Posted April 16, 2014 What's your elevation and current temp? Quote Link to comment Share on other sites More sharing options...
kennygene Posted April 16, 2014 Report Share Posted April 16, 2014 If your elevation is below 1500, try stock carbs with a 27.5 idle and 280-300 main Quote Link to comment Share on other sites More sharing options...

tdod101 Posted April 21, 2014 Report Share Posted April 21, 2014 If the carbs are from a 440 they're probably 36 mm mikunis, don't toss them out do a trade or sell them Quote Link to comment Share on other sites More sharing options...
bansheerider313 Posted April 22, 2014 Author Report Share Posted April 22, 2014 They are 34mm I think, but definitely going to sell them.I have a 40mm pwk im thinking about doing a 2 into 1 carb on it. Quote Link to comment Share on other sites More sharing options...
