Oh, don't worry about the tire sagging, it'll take care of itself as the tires wear in.
As the tires wear they lose rubber so that means that they bulge out more because there's less rubber holding the air back, voila ! sagging gone !

RE: 10-30 vs 10-40 oil
Since I believe everything I read on the internet, could you post pictures of the "sagging tire" and the inflation valve for the handle bars?

If you would put your head in a helmet it wouldn't be empty.

RE: 10-30 vs 10-40 oil
The handlebar end weights are really pressure relief valves (I suspect they double duty) not unlike the pressure relief valve you see on pressure cookers. If these valves are loosened or lose their calibration handle bar pressure will suffer and the result in sag. Attempts to repressurize or use nitrogen will not be successful unless the pressure relief valve is repaired or attended to.

Adding heated grips can affect the relief valve as the additional heat will cause a pressure spike. While the bars can handle it (if you use factory supplied bars) the relief valves will need a slight adjustment with the seasons.

Honda sells a special tool for this, do not try to adjust them without this tool as it will void the warranty and cause your sperm count to lower. Why this would affect the warranty has never be properly explained to me.

Who would have ever thought? I guess I won't believe everything I read anymore.

RE: 10-30 vs 10-40 oil
My CB1100 had Yamahalube 10w-40 from the dealership at 600 miles, and at 1100 miles I swapped it out with Castrol part synthetic 10w-40 (I wanted to do 10w-30 but it was cheaper to get a jug of 40).

I just swapped it again at 3300 miles (Castrol didn't give me any warm fuzzies and I couldn't wait to hit 4000) with Amsoil 10w-30. So far, having fresh oil in the bike has made it extra smooth, I wanna say maybe even smoother than when I first rode her home. I can't wait to see how well this Amsoil will hold up over the next few thousand miles.

Just ordered HP4 for 1st oil change. We'll see how it does. I've always run manufacturer specific oils on my bikes & outboards.

I am currently on Amsoil 10W30 too, going good so far. I really wanted to try that HP4s full synthetic from Honda..think I'll run HP4s next time..

RE: 10-30 vs 10-40 oil
I went with the HP4S full synth 10/30 in mine, hope to get 4K miles out of it between changes.
Since the user manual only had 10/30 listed, that's what I went with, if I had known the service manual also approves 10/40 I probably would have went with that for the summer months, and 10/30 for cooler months.
Then again, the engine is new and tight, so maybe 10/30 IS the best way to go for now, regardless of outside temp?
I chose Full Synthetic thinking the air cooled could run hotter and Full Syn will withstand high temps better.

RE: 10-30 vs 10-40 oil
I'm using 10W-40 with no issues. Aussie manual recommends 10W-30 but also has a graph indicating for hotter temps 10W-40 is fine. It regularly gets to 40 degrees celsius here in summer and I've always run 10W-40 in my inline-4s.

HP4 is a synthetic blend. HP4S full synthetic. To my knowledge the 4S doesn't come in 10w-40 only 10/30. I wanted to try 10/40.
