Carburetors can be the most crucial and unfortunately, the most confusing element to a great running motorcycle. Through many years of research and experience, Dicks Racing knows how to modify and tune your carburetor to reach its maxiumum level of performance.
Carburetor Modifications - Service Details
(STAGE 1)(36/39 MODS) The stock 36mm KTM 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 ($295).

If you have something other than a KTM 2-stroke, don't feel left out, we have got you covered.
One of the biggest problems with air/fuel delivery devices is TURBULENCE. This device is installed on the front side of the slide/butterfly and protrudes into the intake tract where it counts. Unlike other products, the TORQUE WING divides the airflow into 4 quadrants with an air gap on the outside to equalize pressure no matter what throttle opening. You can expect improved throttle response and power delivery in addition to more torque.
For 38-40mm carbs. If you are looking for more Low-End Power, this is where to start. These mods were featured in the Dirt Bike magazine test of the YZ 250 in addition to the Hi-Torque head mods described in the 2-Stroke engine section. These mods also work on 4-Stroke models such as the CRF 250 that came with a 40mm carb or any application where improved response and ridability is needed. In the case of the YZ 250, the lack of low-end combined with the big hit in the mid-range makes the power hard to manage. By reducing the size of the the bottom half of the carb bore, low end power is improved without sacrificing mid-top end power. On the CRF 250, the notorious bog is eliminated without losing peak power. Note: cannot be used with taper bore mods or 36/39 carb mods.
Mods are seperated into 4 stages. Stage 1 eliminates hesitation and bogging associated with stock carbs. Stage 2 is taper boring the carb for more power. Stage 3 involves adding the QUAD FLOW TORQUE WING that eliminates turbulence and increase torque and response. Stage 4 is the installation of the INTELAJET that adds a seperate air-fuel delivery device that features external adjustability, improved response and fuel mileage.

Other than the piston, the moving parts in the head are the highest wearing items. Rebuilding includes: replacing valves, machining the valve seats straight and matching to the valve, replacing valve guides(if required), and replacing valve seals. If you want more power, now would be the time to consider head porting while the head is apart.
