How do you avoid spark plug failure during a trial?
- Never leave your bike's fuel tap on when you are not riding. This is especially important for the journey to a trial - the vibrations cause fuel to leak into the cylinder and wet the plug, and it becomes difficult or even impossible to start the bike.
- Use a new spark plug at the trial. Nothing beats the ease of starting, the reluctance to stall, and the pure performance of a new spark plug. Since plugs are about R35 each, it is worth it to have a new one every monthly trial. One strategy is to fit a new plug for the trial, then swap it out when practicing so that the plug is fresh for the next trial. Every few months the "trial" plug becomes the "practice" plug and you buy a new "trial" plug.
