The End Result
Thenew filter housing has a much larger volume than standard and the engine breathes through a modern Montesa 315 filter. Thepathway for filtered air is directly into the carburettor’s throat. Engine response is a little quicker offthe bottom end and it keeps on revving out where the original Yamaha filter system seems to restrict the upper RPM. In addition it is substantially lighter and looks trick. Study the photos and how the final product looks on the machine. I hope you are impressed and inspired to try your own solutions!
