R&D Racing Keihin Power Bowl for the CRF450X

CRF450x Float Bowl

Another new product on the market is the Power Bowl, a product recently released by R&D Racing. This billet aluminum float bowl not only has more fuel capacity for the times your carb burbles over the breaking bumbs or choppy whoop sections, it also is tunable and has a more powerful accelerator pump. You can tune the leak jet to achieve better timing for the accelerator pump which in turn cleans up your pilot circuit for a crisp throttle response. Owner and designer Dean Dickerson explains his product like this: “With the advent of high performance 4 stroke engines, carburetor hesitation is a far too common occurrence. Temporary lack of fuel supply, caused by air pockets finding their way to jet passages, also cavitation in the accelerator pump, can quickly deflate a rider’s confidence in his machine. The R&D Power Bowl is a sure fix for these problems. During hard landings and high speed impacts, excessive fuel splash currently exists. Splashing coupled with excessive clearance around the production fuel baffle, allows air pockets to reach the main and pilot jet, resulting in an extreme lean condition, commonly known as bogging.

“This new carburetor bowl, designed with our new Zero Tolerance Jet Chamber, minimizes existing clearances eliminating the possibility of fuel evacuation around the main and pilot jet area. (no bog).”

Most of that reads like Chinese to a mechanically retarded person like me, but Dean insists that his product is the answer until all production bikes have electronic fuel injection figured out.

A BETTER SOLUTION!!!
R&D’s Power Bowl, the cure for unpredictable carburetor performance, common in todays motocross bikes.

MIKE ALESSI #800
My bike runs cleaner around the whole track …no bog, no hesitation any where, it also quicker off the start.
I used the Power Bowl on my RED BULL Factory KTM bike for the entire 2007 East Coast Supercross season,
thanks R&D, for a great product.

PROBLEM SOLVER
With the advent of high performance 4 stroke engines, carburetor hesitation is a far too common occurrence.
Temporary lack of fuel supply, caused by air pockets finding their way to jet passages, also cavitation in the
accelerator pump, can quickly deflate a riders confidence in his machine. The solution? ”R&D’S POWER BOWL”
the complete answer to a real problem.

JET CHAMBER
During hard landings and square edge impacts, the production Keihin carburetor design, allows fuel to splash
away for the main and pilot jet chamber. Jets temporarily exposed to air pockets, will cause any engine to misfire,
commonly knows as “BOG”

The R&D Power Bowl, is designed with the new ”ZERO TOLERANCE JET CHAMBER”.
This new design redirects fuel during hard impacts, creating maximum fuel exposure during extreme conditions,
eliminating the possibility of fuel evacuation around the main and pilot jet area, completely eliminating the possibility
of misfiring.

ACCELERATOR PUMP
R&D’s ANTI-CAVITATION accelerator pump is state of the art, designed with two separate fuel ports. Port one,
is positioned at the HIGHEST point in the A/P chamber, allowing entrapped air to escape through the leak jet orifice.
Port two, is isolated LOW in the fuel sump, assuring ‘FUEL ONLY’ into the venturi, unique to R&D’s A/P design, and is
the key to our superior performance.

PUSHING THE ENVELOPE
With all the new advances in the ”R&D POWER BOWL”, we also included an externally adjustable leak jet for fine tuning,
it’s just a quick and easy hand adjustment. The ball check valve has also been redesigned, relocated at the bottom
of the pump cover for a more consistant fuel supply. The stock steel ball in the check valve has also been replaced
with a nylon type for an improve responce time during hard landing and hard impacts.
