I'm not saying this idea is not weird, however, he's talking about one of those bags that you roast a turkey in - rated to 320 degrees, the oil wont melt the bag.

LOL! With my "garage skills" anything could happen! Bag splits...I trip...dog jumps on me just as I remove the bag...etc.

I tend to agree with you. However, most folks, including the Harley dealers do not spend the time to pre fill new oil filters. It takes more than 4 seconds for the filter to fill dry. Even though I do pre fill my oil filters with a few ounces before installation, if you watch your oil pressure gauge after a complete oil change, it does not register even when the filter is pre filled, for aproximately 5 to 6 seconds or more. Food for thought!
You might consider that the Twin Cam filters oil before it cycles though the engine. With a "puck" device that extra dirty oil still cycles though the engine, being pushed by the new clean oil, and then gets evacuated. With your "bag on the filter mount" method you create a complete oil starvation condition through the entire motor. Will it hurt anything in 4 second? I don't know, but that a quart of oil that didn't go though the motor, and a quarts worth of "dry" runtime.

After reading posts about draining the oil and leaving a 1/2 to a quart of oil in bike, I thought about ordering one of the kits advertised in J&P cycles that screws on to the filter base. They were on backorder and seems to have been for a while. It was time to change my oil for the 1st time since I bought my bike a couple of months ago and I was concerned about leaving dirty oil in my bike. What I did was go to the local grocery store and buy a turkey basteing bag. It showed it was good up to 320 degrees. Took the bike out and rode for about 10 miles and took the filter off and drained the oil. Filled oil tank and then put bag around oil filter base and tightened up end by twisting bag at base. Started bike and let run for about 4 seconds. Had a good quart of dirty oil in bag. Took bag off ,put new filter on , put new quart in tank, checked for leaks. All is good. Hope this helps someone . 2004 Road King Classic

My observation is technically accurate and correct, and I tought it was worth consideration for the topic. No one else who replied recognized the issue that I identified. If everyone is good with running a dry motor for a few seconds then Ok, but I would also add that we have been told for years by lubrication experts that the majority of wear in a motor occurs during the first few seconds after start up.
