Anybody know if the aftermarket paper oil filters, such as the one Mike's carriers significantly reduces oil flow? Seems to me that they would be quite a bit more restrictive than the stock screen.

Thanks for the responses, I was hoping that possibly someone had quantified any differences in flow by measuring the oil pressure after the filter. I have used Mike's filter for several years on my bike but this spring I had a connecting rod big end bearing failure and would like to know why it failed. When I tore the engine down I also noticed that there was some galling on the small end bearing of one of the rods so I got thinking again about oil flow.
Oil pressure has no real meaning on these engines. IIRC Pamcopete had done some measurements................about 14 or 15 psi when engine first started (cold thick oil) and drops down to maybe 2 or 3 psi when the engine and oil are hot. The ball/roller bearings in these engines don't need much pressure, they just need oil flow.
There's a good chance your bearing failure was due to abuse by POs. POs have tortured these engines.................running with low oil levels, wrong type oil, gas contamination in the oil sump, etc.
