2-Stroke Carburetor Mods

Carb is bored in such a way as to not lose any low-end normally associated with overboring. Our method results in a broader range of power throughout the RPM curve. In essence, a 36mm carb can have the advantages of a 39mm without the downside, which is loss of low end velocity. Click on 2-stroke carb mods for more info.

In addition, a Dial-a-Jet is installed to compensate for the changing bore size. This device works off of engine load and is self adjusting. The unit is externally adjustable and allows for leaner main jetting that in turn provides a wider range of elevation operation. Unlike a powerjet that delivers raw fuel, the Dial A Jet delivers pre-mixed air and fuel for a pre atomized power source. The whole process includes complete dis-assembly, boring, cleaning, re-jetting and dial a jet installation. A spec sticker is installed that lists the jetting that is inside and a installation/tuning sheet is included ($350) See Review section for MOTOCROSS ACTION test of the carb mods you are reading about.   

If you are looking for even more power, consider the DICKS RACING HEAD MOD. This increases pulling power across the board. For use with or without racegas, your choice.($125)
