how often clean spark arrestor?
I just cleaned my spark arrestor for the second time in the last 1,000 miles or so. It was pretty dirty again. I've been riding a daily for short trips in the city and it's been pretty cold here (well, 30's and 40's). Should I chalk this up to lots of warm ups? Or is this a sign of something else going on? It's been running great, never a hickup. About 21,000 on the clock.
