do i need to change my jetting?

[Gryphon]

I bought an fmf torque pipe for my kdk, i ride at and above 2700 feet, do i need to change my jetting or needle position? im asking because it cuts out every once and a while. Oh its a year 2000.

KDX200 or 220? What's your present jetting? Did it cut out before you installed the pipe? What's your average riding temperature right now?

What did you start with? 9 times of 10, the answer to, 'Do I need to rejet?' is 'Yes!'..cuz I don't think most bikes are correct to start with!

re: 'cutting out'. That isn't a jetting issue...unless you're referring to a fouled plug.

It's worth the trouble to get it right.
