2004 DS650 Baja X second gear when u pin it all it does it sputter u have to get it to about 3500rpm before u can pin it and have no sputtering........ on top end it runs awesome but on bottom end it sputters this is fixed if i take my air box lid off so is it my jets that i need to change?? Im 2450 feet above sea level

 

did it just happen or was always like that. and what have you messed with latly?

 

no its been like this since i got it about 2 months ago thought maybe it was normal when i first got it but i think the jets needa be changed maybe the pilot jet?? and i havent touched anything

 

and its in every gear it sputters when u just pin it really fast not just in second

 

its probably good to go threw the carb first. try that.

 

when I was having that problem it was rich. what main do ya have in and where is the needle? elevation?? It may work to just raise the clip on the needle a bit but most likely have to change a jet.

 

2500 ft I see it now. With no mods I had to drop the needle down one to the second to the top clip. Use the stock main jet. Get a slip on and then move the needle to the second to the bottom with the stock main. Better yet get the end cap from hp research. I am at 3500 ft.

 

The elevation hear is 2450 and i dont no the jets but they are all stock

 

alright im taking it in for a tune up at a local dealer ill have them do it for me

 

Have ya got into the car at all. IT is really simple.
