i am wondering if they make this system for the 400ex and if they do does anyone know where i can buy one i've searched all over the internet and places only sell them for dirtbikes

 

ive heard their BS and a waste of money.

 

i heard that they work pretty well for increasing the bottom-end i read a lot of reviews and everyone said they felt a noticable difference. i just would like to know where i could get one

Thanks

 

anybody got an ideas?

 

correct me if im wrong, but the only quads ive seen them for is the Banshee and YFZ... the YFZ owners at blue traxx said they didnt wory well for their YFZ's... i dont think they have them for the 400. Good luck, sory im not much of a help. Try www.Rockymountainatv.com

 

they work a little but not worth the $80-100prices for them .they will help a little on bottom end .e- bay sometimes has them cheap

 

you could get a system for a diffrent quad as long it was for a four stroke and make it work for the 400. the more nos you put in the more of a risk you have of blowing up your engine tho unless you rebuild the engine to take it and then it could take alot. just some ideas

 

i felt a difference in the bottom end. i would not recomend running the dsp from one make on another. the pieces have tolerences and clearences specific to each models carbs.unless you hve the same carb on each model or make of bike,wait until one becomes available.
