1,000 mile service
Going to be taking in my 08 Classic in a few days to have everything changed and serviced. I plan on taking in Amsoil 20/50 for the engine and primary and take in a qt of 80/90 Amsoil severe gear lub for the transmission. What are your thoughts on going to synthetic at 1,000? I did not see a problem since the screaming eagles come out of the box with full synthetic. I have heard stories about waiting until the valves and rings have seated before changing. I guess I do not see how systetic oil would slow down or stop seating. My goal is to help the engine run cooler and quite the shifting noise in the transmission. I did install a Jag vertical cooler when I bought the bike and wow what a difference that made in heat.

RE: 1,000 mile service
I'm at 850 miles and am planning to do the same thing at 1000. I'm going with the oil in all 3 compartments. I deal the stuff but still have been debating on which way to go. Took a look at the kinematic viscosities of each of the gear lubes and the oil and compared. The oil and the 75W-110 are comparable at 20.1 and 20.4cSp respectively. The 75W-90severe gear lube is at 16.7. If you're looking at the 80W-90, product code AGL, it is at 14.9, so it is the "lighter" of all of them.
Just some numbers FYI.

Not sure if there is a way to edit posts, but can't find it. To clarify above, these KV's were at 100C. The severe gear lubes and the oil also pass the ASTM-D892 foaming test with no problems. All have viscosity indexes greater than 150, the gear lubes are a little higher.

I switched to syn3 at 1k, them Amsoil at 5k and installed a jagg vertical cooler by 10k, and am approaching 30k with no problems on my '07 dyna. I run amsoil 20-50 in all three holes because it's easier to just keep a case of one kind of lube around.
