Hi, I just got a new 2002 400 SX and I was wondering if anyone has any experience with the range of the stock fuel tank as I will be racing enduros
and mx. I will also be using a T-4 silencer and I was wondering what jetting
others are using. Thanks!!!!!!!11:)
I get between 15 and 20 mpg with my 400 SX. I've never ridden alot of sand like you guys have up there, so I don't know how that would affect the mileage.
For enduro's and HS I'm running a T4 with a quiet core, 2" cap and the following jetting.
OCEMN needle, 4th clip
170 main
1 turn out on fuel screw
