Royal Enfield Seattle (aka Ducati Seattle) doesn't have their RE supplies order yet, so they have no oil filters yet. Darn.
Still, I had some Amsoil 20W50 motorcycle oil (JASO MA) in the garage so I changed out the oil at 300 miles. I plan to get an oil filter and do the next change at 600 to 750 miles, long before the 2,000 miles the manual recommends.
I really liked how Amsoil helped my Buell Blast thumper AND Buell XB9S run cooler. So I have no problems using it in the Bullet.
The drain plug I opened quite gingerly after hearing of stripped threads. I used a torque wrench to see what it was set at but it released so quickly I couldn't get a reading. So putting it back on I was very careful to not overdo it. 19mm plug.
I measured the oil to be a little less than 2 quarts, so that is what I put back in.
The oil screen suction filter wasn't very dirty and two magnetic oil plugs weren't that filled with iron filings. My Buell XB9S had more stuff on its magnetic plug. Oh, when I got the bike, the shop had changed the oil already, as recommended by CMW.
Below are some screen shots. The split-screen shot shows the oil level after filling and the second shows it, after settling, following a 10 mile ride with the new oil. I checked the air filter and found no oil contamination. I'll check it again after a longer ride.
Anyway, I rode for 120 miles yesterday and today. The motor is smoothing out as i am getting used to the handling. It really is a fun motorcycle.
