yeah, on my previous car (BMW 535is) i awlays used the purolator.......but after reading some of the posts around here there's been much said about the paper on some getting sucked out, not filtering correctly, etc. A lot of bad press about the FRAM ones in paticular. All news to me. ...........I mean damn, how much suction is there on these bikes??? right now i got one of the K&N oil filters on it, probably cause the salesman was taliking so much about it, and I hadn't stumbled onto this forum yet..................I'll give the puro' a shot, i got about another 800 miles before the next oil change but.......uh, yeah!!
