Lots of talk on the net about no using anything less than30micron filter on Sportster.
amsoil said 04 and newer sportster has better pump and can handle their filter.
I have an 08 1200c, been using amsoil filter since 1k oil change. now have about 14k on the bike.
What to the other owners of 04 and newer sportsters use for oil filter and how many miles on the bikes. Anyone herd of any issues?
