Detailed Description

POWER BOWL 2 (FITS MOST MX AND OFFROAD MOTORCYCLES AND QUADS!!)
Redesign, now with left side adjustable leak jet, totally user friendly.

SUPERIOR FUEL FLOW SYSTEM
The PowerBowl's design greatly improves every aspect of your carburetors's ability to deliver
fuel evenly and consistently. It's smooth inner surfaces and perfectly matched fuel passages
eliminate air cavitation and accelerate fuel delivery. The PowerBowl is a completely integrated
design, the accelerator pump is also reconfigured, the maximization of both bowl and pump
create a whole new level performance through efficiency.

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
Carburetor hesitation is a far too common occurrence, in todays high performance 4 stroke engines.
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 serious 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 light weight nylon ball, for an improved responce time during hard landing and extreme impacts.

OFFROAD FRIENDLY
A properly tuned carburetor is the key to a great day of riding. The Power Bowl is designed with easy access tuning in mind,
a properly tuned A/C pump is an absolute must, when optimum carburetor setting is the goal.
