I just got a DG Stage 2-Xellerator Exhaust for my 03 400EX,i've only ride'n it with it one for maybe an hour and today when i went down to try and get the quad started it wont kick over.the only thing it will do is make a pop''n noise from the exhaust. its not the barrery and the fuel's not frozen. the only thing i could think of is maybe because its been between 8 and 30 Degree's outside.But the 400EX is my first quad owning and i've only had it about a month so any help or tip about starting it in the cold or why it wont stary would be of great help

Thanks~

pump the thumb throttle a few times, the carburetor is equipped with an excellerator pump that shoots a jet of gasoline into the intake, kinda like a primer on a lawnmower.

 

Thanks for the advice about start'n it in the cold

but do u think that the DG Stage 2 Exhaust would hurt the quad at all? cuz i have the rest of it all stock

 

i think its just the weather u have. u did re-ject for the new pipe right? or did u not need to? i dont think thats the problem. go with 420ex's idea

 

No, i dont knw to much about quads myself so i just put the pipe on there but do u think if i did re-jet it that it would help?

 

you might be running lean, get a dynojet jet kit and it should make yourquad run right.

 

or put your stock silncer back on

 

yea u might be running alittle lean

 

Hey did you try the choke? If you did then just spray some starting fluid down the intake, and it will fire. If it doesn't fire you probobly have an ignition problem.

 

Yea i did try the choke lol

but i'll have to try spray'n down the intake

Thanks everyone and once i get some free time i'll try them and let u guys no how it goes

but anyone else who might wanna give me some tip's to i'd appriciate it
