I am not a mechanic or a representative of any motorcycle or tool manufacturer or anything else official. This page is only my notes on doing this procedure myself. Although I believe what I have documented here is correct, I make no promises and you do this at your own risk.
Water and debris can build up in your carburetor, after long storage or riding in dirty or wet conditions. There is a drain that allows you to bleed such contaminated gas out of the bowl. My service manual suggests doing this every 5000 km or after a winter’s storage. Draining the carb is also good practice before winter storage to avoid having gelled gas varnish the inside of the carburetor.
- Large Phillips screwdriver.
- 3mm hex wrench.
- 1 metre3 feet of gas line hose.
- Small glass or plastic container to receive drained gas.
- Drained gas is toxic and flammable — be careful.
And run the house into a container on the ground.
In this photo, the end of the hose wouldn’t stay in the container — it kept wanting to curl up. So I just ran it through the hole in the handle of a pair of scissors, and that kept it in place in the container.
Congratulations, you are done. You may find the bike a bit harder to start next time, since the carb bowl is empty.
