We decided to produce this kit. In the past, we have produced quite a few off road kits and installed ooodles of them in stock and previously rejetted Hondas, Yamahas and a smattering of others, but never really marketed them well. If you are familiar with AMA level roadracing, you'll remember that Factory Pro was the preferred jet kit for 9/10 of the field. Our kits were preferred because they made the best lowend, midrange and topend. Factory Pro also owns several tuning patents, including in carburetion and dynamometers.

This KTM Carb kit is the only carb jetting kit that was developed on the EC997 Low Inertia Eddy Current dyne system using a 5 gas EGA. Experience the same level of carburetion refinement that AMA Pro's used.

Designed to deliver best mileage with improved throttle response and better power at both full and part throttle. Can be significantly better than other jet kits.
What was amazing was that even at just above idle, in first gear, you could snap the throttle a teeny bit and lift the front wheel over a log- making this jetting kit awesome for best throttle control.
