Carburetor cleaning

One of the less exiting but absolutely necessary bike prep you need to do before going on a desert race is cleaning your carburetor. Even if you don't do races you should clean it once every year anyway just to save you trouble. A carburetor is an ancient piece of technology for combustion engines as compared to injection. But it has its pros and cons. On the plus side is that since the construction of a carburetor is so simple it is mostly possible to fix it, should a problem occur, when you are out in the middle of nowhere far away from your sterilized garage. You basically cannot fix an injection. Most people will carry an entire injection kit (or several) as a spare when doing rallies.

Removing and cleaning jets

My cleaning procedure consists of taking apart most of the carburetor. Cleaning each part and checking for wear and tear. All jets, the mixture screw, needle, float, float needle, the throttle valve, the accelerator pump etc etc. And when everything is nice and clean I put it back together again.

When I put it together again I usually put just a little bit of thread lock on the screws to make sure the stay fastened. I also put some thread lock on the mixture screw so it won't come lose. (I actually lost my mixture screw in a rally in 2008)

As I said, not the most exiting bike prep but a carburetor problem can possibly ruin an entire race so it is definitely a must.
