I noticed in the owners manual for my 2016 Honda Rancher that Honda recommends I service the spark arrester every 100 hours of operation. I'm at about 290 hours now. I went ahead and followed the instructions in the manual and produced a how-to video.
I feel it's safe to assume the Foremans and Rubicons will follow the exact same protocol, as the engines and exhaust are nearly identical to that of my Rancher, with the exception of a larger cylinder bore and larger throttle body. I hope somebody finds this helpful.
