CRF450X Fuel Injection

Someone sent this picture to us. It appears to be a CRF450X with fuel injection. We are looking for more information on the bike but can’t find any. If you happen to know the source of the picture or the owner of the bike please drop us a line. It looks to be a non OEM factory setup. We’d love to talk to the owner and feature the bike here with some more information. Anyone have any info on this Honda CRF450X?

CRF450X R&D Racing “The Original” Power Pump W/ALJ

colin — Thu, 31 Jul 2008 07:45:48 +0000

From R&J Racing comes “The Original” Power Pump with Adjustable Leak Jet (ALJ). This part ends the pain and drudgery of spending hours adjusting the jetting on your bike, making the process incredibly fast and simple. It allows you to tune your accelorator pump setting in seconds, generating an extremely quick and crisp throttle response in your Honda CRF450X or other dirt bike. The kit includes four parts: the power pump, adjustable Leak Jet, Linkage Spring and Leak Jet Plug. The “Anti-cavitation” accelerator pump chamber is designed with two separate fuel ports. This unique design creates a natural purge with port one, meaning that entrapped air escapes through the leak jet hole. This also means that the second port is isolated and low in the fuel sump area resulting in fuel only into the venturi, not air.

“The Original” Power Pump w/ALJ is very easy to tune, meaning you can start getting quicker, more crisp throttle response almost instantly. This improves acceleration and power as a result, and of course makes you a better rider. This pump is great because it is essentially bolt-on power for the Honda CRF450X. There is no need to be an engineer or professional rider to get more power and throttle response out of your bike, parts like this can do the job nearly as well. The best part is that no drilling or modifications are required. Unlike some parts which are nearly impossible to install, and require you to rip apart your entire bike, “The Original” Pump from R&D Racing can be installed easily for instant improvement. At $100, it is also not a huge detriment to your wallet for the improvements it provides. “The Original” Pump fits most FCR-MX carburetors, including the Honda CRF450x. I would recommend this part to anyone interested in quick effective performance increases, to both track and trail riders.

A really great part to purchase for the Honda CRF450X if your sick and tired of burning your fingers when adjusting a stuck fuel screw is R&D’s Flex Jet Remote Fuel Screw. This solves not only the first problem, but also eliminates the possibility of the fuel screw vibrating loose while riding.

This revolutionary new remote fuel screw has a very simple yet effective flexible shaft design. R&D claims this design is so effective it has become the new industry standard. With this flexible shaft, the fuel screw is now easily accessible, meaning that quick adjustments can be made rather than long strenuous ones.

Loose fuel screws which plague many riders, especially those of the Honda CRF450X, are a thing of the past with the Flex-Jet Fuel Screw. The product has the ability to hold its setting no matter how much vibration , something many riders will be happy to hear. This product is excellent for both track and trail riding, and is almost essential for those who are sick of burning their fingers, or having any sort of hassle with their bike’s fuel screw. This product fits most bikes, including the Honda CRF450X. Installation is a breeze and the price is worth it, considering the amount of hassle it saves. The R&D Flex Jet Remote Fuel Screw can be found at R&D Racing

F2Racing.net Fast Cap for the CRF450X

CRF450X - 450X Admin — Fri, 11 Jul 2008 19:41:52 +0000

F2 Fast-Cap

The F2 racing Fast-Cap is a product developed by the great minds at F2 racing, which is designed to keep the flow of the fuel constant. When testing the world’s fastest bike, researchers at F2 noticed that it would start to “run lean” at very high speeds, as the stock float bowl cap allows fuel to flow away from the center, where the jets are fed. With this $30 cap, performance is improved dramatically, as the fuel flow is more direct. At sustained high speeds, the problem of the bike “running lean” or not getting enough fuel, is eliminated and a far more consistent top speed is achieved. The Fast-Cap is a relatively small after market part that fits on to an existing carburetor. F2 claims that in nearly any kind of racing, the top speed is not only more consistent than with the stock, but also higher. On the world’s fastest dirt bike they were able to obtain another 800 RPM and an extra 6 miles per hour in the top speed! And this was with no other modifications, just the simple $30 F2 Fast-cap.

This product has been proven to be beneficial not only to pure racers, but also for trail riders. The cap is said to achieve a far more constant fuel flow, which means a far crisper throttle response, exactly what many trail riders are looking for in a product. Reviewers have claimed that they saw a definite increase in smoothness over the stock setup, especially in uphill climbs and large jumps. The Fast Cap is also excellent at improving crispness across obstacles and turns, simply because it is better at controlling the fuel flow than the stock parts. This smoothness in control and throttle response means that many people will become more confident riders, never having to worry about stutters or slight losses in power, at the top of a hill or jump, where it is needed most. The Fast-Cap fits all FCR and Kehien 2-stroke carburetors, comes in red or orange, and is very comparably priced at $30.

CRF450x Magnetic Oil Filter Cover

CRF450X - 450X Admin — Fri, 23 May 2008 05:34:17 +0000

R&D Racing Keihin Power Bowl for the CRF450X

CRF450X - 450X Admin — Wed, 21 May 2008 05:33:01 +0000

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: â€œWith 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 riderâ€™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.

â€œThis 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).â€

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.

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,

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.

Quick Shot Acclerator Pump for CRF450X FCR Carb

CRF450X - 450X Admin — Sat, 06 Oct 2007 03:57:35 +0000

With a street price of about $40 the Wirtz Quick Shot accelerator pump cover is a great addition to your CRF. The aftermarket accelerator pump covers help put more fuel in the intake when you crack that throttle open. I personally use one by Boyesen. This mod does have it’s opponents though. It’s a part that may or may not improve the feel of your bike depending upon your riding style. If your slow on the gas and give the motor plenty of time to respond on its own then this mod isn’t for you. If however you want a snappy ride try one of these out.

Compared to some others on the market this item is made out of billet aluminum while some of the others are cast.

Here’s the manufacturers detail and a link to the product on their site.

Quick Shot Stock accelerator pump covers permit only a 60% – 70% fuel charge in the pump chamber. Turn the throttle and air in the chamber is compressed and fuel is delayed. The result: Hesitation or Bog. The Wirtz QuickShot cover completely fills the pump chamber with fuel, and provides instant fuel delivery, eliminating the hesitation and bog.

*Fits all 4-Stroke Keihin FCR carburetors
*Instant response to throttle movements
*Improved low end performance
*Reduced hot engine stalling
*No modification required – simple bolt-on
