KDX 250 Jetting

[jackalay]

I have a 92 250 and need a good starting point for my jetting adventure. I am at about sea level, Have an FMF Fatty and Boyesen Reeds, Wiseco Piston etc.

I run a 162 main, one step leaner needle in the second position from the top, a 38 pilot, and I cut 1mm from my slide. This is much leaner than stock, and the difference in performance is huge. With the stock jetting, you can fog for mosquitos.
