DRZ400 Upgrade Kit- Complete Keihin FCR MX 40mm Carb Assembly
This product is a linear power option for a more gradual power delivery.
Includes everything needed to run your bike properly!
For your dirt bike to perform as shown in the video below, please select all blue upgrade buttons above before adding to the cart.
This video shows a completely stock motor with a full exhaust in addition to this carb upgrade.
We also have a “rebuilt option” for a more economical modification.
This purchase will include the components listed below when you select all blue upgrade buttons above:
-Gas tank nipple (for the stock gas switch to work properly)
-TPS sensor (ready to plug into the Suzuki wiring harness)
-New adaptor boots (for easy install and runs the bike’s throttle cover to keep out dirt particles)
-Tuned for each order (Please include in the order notes page: elevation, bike mods, mileage and riding style)
-Upgraded float bowl (for the fuel-flow in any angle that the bike is leaned: whips, wheelies, off-roading, etc.)
-Correct needle (allows for a smooth power band and the ability to pull endos without stalling the engine)
-Black Neoprene Keihin hoses (these last 3 times as long as the Keihin Pink hoses stock)
Keep note that this carb will still run great without any upgrade options selected. When all upgrade options are added, this carb will show perfect throttle response and a gain of 10% power over the stock option. Also, this is a reverse linkage accelerator pump, so the pump will twist as fast as the throttle does.
On the checkout page, we require the exact year and model to ensure a perfect fit.
Please include your exact bike year, model and sub-model (along with any questions/comments) when checking out, as we have multiple variations available.

I ordered all options with this carb I wanted more power out of my Drz400sm and now it has it. I wish I bought this sooner it’s kind of expensive but worth every penny! It wasn’t to difficult to install, the video they gave me helped alot. The air box was easy all you need to do is get a heat gun and a utility knife and it cuts it like butter. Oh did I mention it was a plug and play it fired up first time no adjustment needed. THIS IS THE BEST MOD YOU CAN DO FOR YOUR DRZ!

For a woods rider like my self i didn’t see myself looking to hold it wide open all the time and i wanted the lower end to not be compromised, this 40mm is what was recommended. I still thought it was too big because everyone is recommending the 39mm.
GET THE 40MM if u want perfect throttle response WOW.
