Anyone match up an aftermarket filter yet?

I bought a Mobil 1 (M1-110) filter today. I have almost 500 miles on my bike so I will do the 600 mile oil change within the next 2-3 days. I have two OEM filters on backorder from RMATV
but I have no idea when they will get here. I have used the M1-110 on plenty of Hondas before with no issues.
Most people don't replace the drain gasket when they do oil changes, but I do. RMATV had those in stock. They are around $3 each. If the drain gasket was a (soft) flat washer, like it is on most Hondas, I would probably reuse it, but the Yamaha version is a ridged crush washer that is pretty delicate. (IMO)

I already have M1 10W40 4T "Racing" oil in my bike. I had to dump the factory fill when I bought it because it was overfilled and I had no idea how much was in there. When I start my bike the oil pressure light flickers a little until I blip the throttle a little. I am pretty sure the M1-110 filter will not cause the bike to have a lower oil pressure at idle but I will check to be sure. A lot of people worry about the blowoff valve in filters being bypassed and letting unfiltered oil go to the engine, but I am okay with that as long as the filter only does it occasionally. The oil in engines is filtered so many times per minute that a few seconds of unfiltered oil is trivial. Note that the oil pressure light only blinks on startup, especially if the engine is warm. My guess is the hot oil drains to the crankcase and since it is on the sidestand the oil is off to one side. It takes a few seconds for the oil to circulate. I've never had a bike do this before but I am confident it is okay. That said, I monitor the oil pressure light closely on any vehicle I operate. In fact, when I change oil filters and I cannot prefill the oil filter with oil, like it is on the R3 since the filter is horizontal I will start the bike after the oil change with the throttle wide open. This signals the ECU to cut the spark to the cylinders to allow the engine to clear out a flooded condition. If you crank the engine this way the RPMs are very low and cause very little friction but the RPMs are high enough to circulate the oil.
