[img]i/expressions/face-icon-small-disgusted.gif[/img] after wide open throttle bursts or rapid stopping quad stalls and is hard starting,cranks for about ten seconds then sputters back to life,any ideas?

 

if its elec start don't use the throttle... no ideas why it stalls i have no prob with mine... do you let it warm up

 

[img]i/expressions/face-icon-small-confused.gif[/img] yes i let it warm for 5 mins before riding, i tried the obvious, like bumping the idle up a tick,new plug after break-in,installed boysen quickshot, i love this quad but this annoying problem just wont go away

 

i have the same bike (07 honda trx450er) And also had slight problems with mine as far as "stalling" is concerned. The fuel/pilot mix screw is where its at man.... Ive adjusted my fuel mixture screw and a bigger pilot (actually 2 different fuel mixture screws) a dsl to be 100% and 175 main, 55pilot, yami needle tc racing / supertrapp full exhaust and curtis sparks air billet filter kit. The things a machine now man. it roars and doesnt restrict it like it does stock. Im sure your use to it just stalling when you tag the throttle or something like when you come to a turn/stop etc at low ends, right? "TracticZero" is right too man, about "warming it up" my buddies that do not run hondas always laugh when we go out because as soon as i get there before i do anything, i start the bike up and let it sit while i get ready etc. Honda says all the trx are on a 10 minute on 10 minute off, then go tip. But i don't do that, i just start/warm it up, then jump on and ride!! hope i was some help....rubbers off the ground all day!! Peace
