Can anyone enlighten me about the design of spark arrestor on the Ace. I have read everything I can find on Google and cannot find out how the spark arrestor is implemented on the Ace. The Parts diagram of the muffler does not show a screen for collecting particles. There is a clean out plug so I assume the particles do collect in the silencer, part number 1262405-489. I have read the federal government requirements for off road vehicles and if I interpreted those correctly, the Ace must have a spark arrestor. I plan to go to some ATV parks in East Texas that require spark arrestors so I would feel more comfortable if I were a bit more knowledgeable.
