what cuppler? 2017 kx250f FMF mega bomb/4.1slip on, no toil back fire screen removal kit and cut right side air box open. I love the white map, is this still safe to run...i ride sand 90% of time and use pump gas. also any dyno figures for kawi running fmf system?
The Shop
Any 250f needs whatever is the most aggressive coupler.
With mods it becomes too lean. This is the difference between "feel" and performance - You would be best with the stock coupler with your mods.
If you can source kawi tuner you could then produce a custom map that meets both your wants - lean with more advance in part throttle regions and then richer at WOT for real pulling power.
