While I was reading through the threads I noticed some talk about air filters so I'll share a tip I've been using for about 15 years.I was given an awesome looking set of velocity stacks for a 1975 cb750 ss that looked so good I just had to but them on the bike.They came with round press fit foam filters that didn't look like they would stop much.Close to same time I was starting to see the ss screen oil filters and the ones used as coffee filters.I did some checking about and found out the ss screen was being used as a stage in some hepa filters also.Its 50 microns or about 9000 holes per square inch and added with oiled foam makes a great air filter.I've used it on a couple of bikes now my compressors and funnels.Handy stuff………...
