All the noise suppressors for your HONDA 4 strokes motocross that we can have can be found here. As the name suggests, it filters out the noise from your coil. The spark is then better. However, it does not restrict your bike. The choice of the anti-parasite is important. Some have gold particles for better spark conduction. Others are made of steel, the performances are then less good but also less expensive.

How to change a suppressor ? It is very simple. In most cases it is simply aimed in the high voltage cable. You just have to loosen it (counterclockwise). It happens that in some cases it is stuck. The easiest way is to cut as close as possible to the suppressor so as not to lose any length. You will only have to aim the new one.
