Jump down to the initial ride review!

The carb comes with everything shown here for the XR650R.

Installing the Edelbrock Qwiksilver Pumper Series carb on the XR650R

1. Remove the seat and tank.

2. Drain the gas then unhook the cables from the stock carburetor.

3. Loosen the clamps on the intake manifold and the air-boot then carefully wiggle the stock carburetor off.

4. Remove the stock throttle assembly and cables (note where they are routed, and route the new ones in the same spot) then assemble the new throttle assembly making sure to lube the new cables.

5. Install the idle cable and the metering adjustment tool to the new carburetor.

6. Wiggle the new carburetor first into the intake manifold then into the air-boot.

7. Hook up the cables from the new throttle assembly onto the new carb.

8. Put the tank back on and hook up the gas line using about 1-1.5 inches of the gas line and the piece of tubing included.

9. Turn on the gas and start it up!

Initial Ride Review!

Took the bike out for the first ride since installing the new carb. My initial impressions are:

The bike starts much easier! The carb does not come with a choke. It comes with an enrichener, but the instructions say on the pumper series it may hardly ever be needed. When cold, just blip the throttle twice, (to squirt some gas in the venturi of the carb), find top dead center and kick. It started first or second kick every time hot or cold.

Off idle. There is no more off idle hesitation. No matter how hard I hit the throttle, the bike responded. The low to midrange in my opinion is stronger. In fact in a couple different situations the front end was coming off the ground where before I could keep it on the ground. Everywhere in the rpm range the throttle is very responsive.

Does it make a big difference on the top end? My seat of the pants opinion is that the difference is not noticeable on the top end. The stock carb when properly jetted works well on the top end and so does this carb. However, Edelbrock tells me that all other settings being equal, (pipe, air filter etc.) this carb makes approximately three more horsepower than the stock carb.

Would I recommend it? For the occasional rider that takes the XR650R out twice a year probably not. That type of a rider probably hasn't uncorked the XR650R either. (By the way, the carb requires the non-epa intake manifold.) For the rider who is looking for that little extra edge, I would definitely recommend this carb. In light of some of the bad press regarding Edelbrock's older carbs, I was a little apprehensive about trying this carb, but after talking to the guys at Edelbrock, they convinced me that this new one was done right and I am glad they did.
