I've been searching for reviews about various intake and exhaust systems (and other assorted accessories) for the M8 Freewheeler using multiple search engines and different state and country locales for quite a while, but all I get are glowing reports about whatever product that particular website is trying to sell you. I'd like to find a site that will say "this air cleaner is junk" if it is junk without them trying to sell an alternative part. There are websites that do in depth reviews on everything from CB sets to hearing aids without pushing a sponsored company, but there doesn't seem to exist any such animal for Harley parts or motorcycle parts in general. I've been mostly going on the experienced suggestions from those in this forum, with great success I must add, but I'm just looking to expand my resources of info if anybody knows of some.
