How to reduce front sprocket wear on Suzuki DR-Z range

On suzuki's DR-Z range, the front sprocket is covered behind and enclosed panel. This panel doesnt allow for mud to exit, and builds up causing excess wear to the chain and sprockets.

One way to fix this with out discarding the cover is to cut slots into it. You will notice that their are 3 moulded slots running diagonal across the cover. Using an approximate 8mm drill bit, drill a hole in the both ends of each of the slots. Use a rats tail/round file to file out the material in between the 2 holes. It does not require much effort to file.

Re-fit the cover, it now will allow dirt build up to exit, access to the sprocket with the hose for cleaning and for inspection, and looks really good aswell!
