New Carburetor for Suzuki DRZ400 DRZ 400 FCR MX 39mm Carb

Installed this carburettor on my drz 400e. The main difference with the stock carburettor is the throttle wheel rotates anti clockwise, so you have to put the top throttle cable on the bottom and the bottom one on the top. The throttle cables are not long enough but they can be made to work.Put the carb in place and connect the cables before you fix it to the air box and manifold so you can manoeuvre it to help get the cables connected. You have to wind the nuts on the bottom cable in ,so it fits in to place and the nuts are behind the connection point. Then use a cable tie instead to keep it in place. I screwed the air mixture screw on the bottom all the way in and then backed it out 2 and a quarter turns and then set the idle with the screw and it runs perfect. It comes all assembled so no need to take it apart. Also comes with extra jets. I am a novice at mechanics but watched YouTube vids to help with the install. It took me about 3 hours but should be much quicker if you use this method. Bike now runs great with loads of power. Absolute bargain compared to the price of a genuine keihin carburettor.

Added tons of power and throttle response. A fairly difficult install but will work with stock throttle cable. You need the allegeher performance adapter kit available on eBay to make this work with the DRZ 400S manifold and air filter boot. Best upgrade to my bike yet

Works great, love it

We are motobike mechanics and there is no way this carby will fit the DRZ400

Good value- had proper jets for pipe/ 3x3. Throttle requires modification

My bike came with a Minuki 36mm carb. You need the Allgeyer Performance kit, a DRZ400e intake boot, and an oem suzuki vaccum nipple to bolt into the engines side of the air intake so the vaccum petcock has something to pull the vaccum from. Everything other than this carb was easily grabbed off ebay for this install to work. Seal the intake adapter that came with the Allgeyer performance kit with a nice layer of RTV on the inside to prevent air leakage. Do not move the engine mounts during install its not necessary theres plenty of room for the throttle linkage you can even get it to fully open and rully close. Pro tip: a washer for the close side of the throttle linkage will help you set the throttle linkage. also a single zip-tie can replace the door that closes around the linkage area for added clearance. Honestly it was pretty stress free. pilot jet is running a little rich dies with choke on during cold start other than that its perfect. one star marked off for mislabelling the included jets and for not including a #40 pilot jet which is what i need. They include: pilot- #42, #45, #48, #52, #55, #58. main- #150-200 at intervals of 5.UNINSTALL THE THROTTLE POSITION SENSOR WHEN REPLACING THE GAS TANK. Then reinstall the throttle position sensor after the gas tank is seated. the factory petcock rubs on the carb when reinstalling the tank theres barely enough clearance but you can make it work if youre careful and remove that TPS
