Correct. For a liquid cooled auto engine (which is what API specs are concerned with) that's higher than you'd see on a typical hot day in traffic. Air cooled engines experience a wider range of operating temps, both on the high and low side, since it's the oil that carries the heat away.
Dino base oil stocks will start breaking down starting at temps above 250F. Synth base stocks are more heat resistant and will typically give you another 20 - 30 degrees above that.
Given that, I still think the trigger for the oil temp light on the CB1100 is ridiculously high. I don't even know of any synth oils that can withstand that temp without serious thermal breakdown. In fact, the procedure that is commonly used to test oils for thermal breakdown is done at 302F.

I don't disagree with your discomfort; and I've added larger oil coolers to air cooled diesel engines. But, the manual for the engine in my truck specifies a normal oil temperature AFTER the cooler as 200°F and a maximum temperature AFTER the cooler as 260°F. Obviously, much hotter pre-cooler. This is for an engine designed in the late fifties with much poorer quality oil than we have today. Oil pressure comes up 10psi during cool down idle! Doing a search, 220°F oil temperatures are normal operation for diesels with a limit of 250°F. Maybe it isn't as big a deal as it seems.

Is that the "hot" smell she has when she is idling? I just chalked that up to new smell...
The dealer is supposed to wash the exhaust system before starting the bike. Unless you picked up yours in the crate, this should have been done for you.

This reputable dealer set it up. Thank you for responding. - Art

NightRider,
Cleaning the headers is on the setup sheet the techs use. That 'hot' smell is the new bike smell. We all had it. Wish mine still did!

After seeing this service bulletin I am pretty sure my dealer did not clean my headers. Mine are terrible looking. Loaded with bad dark areas and spots. Iv seen one other Cb in person and tons of pictures. None look as bad as mine.

Wonder if you could clean them with something now or if it's too late and the damage is done? I'm thinking that Optiglanz guys are talking about would take care of it?

The Optiglanz would probably work. I used blue-b-gone and it also worked. The blue b gone is weird. It doesn't take any elbow grease but it does take 4 or 5 wipe on/wipe off applications to get them clean. Rubbing harder on an application doesn't get them any cleaner.

I was going to order the optiglnz but read somewhere that it only takes off the brown. But I think ill try it anyway. I just wonder what will happen to the paint on the engine/frame if any hits it. I will obviously try my best to not let it touch the paint but I'll be bummed if it does and messes it up.

First, try taking it back to the dealer, show him the obvious failure on their part and ask for new headers. I would assume it is obvious what happened. No need for you to have to deal with this since you paid for clean headers.

That crossed my mind. But I don't think they will for 2 reasons. I have 1200 miles on it so I'm sure they'll say that's just what happens. Also when I brought the bike home I noticed the front right engine cove had a deep scratch into the metal and chiped the clear coat. I called and they said there wasn't enough profit in the bike to fix. Also some of the hardware on the bike was stripped like they used the wrong size allen. So I assume whoever assembled the bike was careless which makes me assume they didn't clean the headers. Just seems to be my luck lately.

A call to Honda of America might be in order.
