Will it hurt the bike or filter to run the Race filter if I run it on the street and track days? Or should I stick with the HE filter?
the race filter needs to be cleaned after almost all track days. i doubt it would hurt the bike but you will be doing lots of cleaning.
i have the H/E one in both bikes clean it once a year
