A Yamaha XS1100 that can do 160 with lots of throttle left?

I got some ocean front property in Arizona....

You need a new speedymeter.

BTW-the XS1100 was last produced in 1981.

+1 on the increased air pressures and head bearings.

I couldn't remember the model year when I posted and still can't. The bike had gone through several owners before me. I used it to get to a union job site that was about 65 miles away.
Only buried the speedo a few times when on an open stretch during the commute. The wind would blow through the helmet so hard it it made my eyes water after passing about the 130 or 140 mark. So the world was very blurry, but I know the needle went past the numbers, and it read to 160. The worst part was the way it made any exposed skin roll and then flap and snap on my neck like a whip. The howling was so bad my ears would ring for an hour. Could have easily been a faulty speedo but no matter the exact speed, the forces exerted on the rider were crazy. I was in my 30's and decent shape, so wasn't an overweight thing.
If I remember correct, I had around 1/4 throttle left.
Didn't mean to offend you with any false claims. All the mods were done to it before I got it, so if there was anything else done I wouldn't have known.

No offense taken, as I was sure you meant a different model. That was just my way of saying, "Are you sure of that, Bubba?".

The FJ1100/1200 could do about 135/140. I still want one of those.

Another tire I discovered last year was the Avon A26 Road Riders. If you don't think a bias ply tire can handle corners like a radial, ask Daytona Mike. He followed my bike all day when we rode the Arkansas roads, and especially on Push Mountain, and I had the Connie laid over farther than it ever had been.
The A26 is available in many sizes including sizes for the early model Connies.

Sounds like most people stay with the 110/80-18 front.  What other sizes have been successfully tried?

Same for the rear 150/80-16.  What other sizes work?

I notice looking thru some specs on the tire sites that a tire can have a larger diameter but yet turn more rev's per mile.  Maybe that was a typo.

Was wondering about that.
I haven't checked the rear size, but the speedo definitely reads wrong. Flowing with crowded rush hour traffic it reads 65, I know were lucky to be doing 55.
It's probably only about 7mph off, and I would rather it err on the side of caution, but annoying nonetheless.

The speedo is driven off the front wheel hub.  My rule of thumb is it reads about 4-5mph too fast at 65 as I've been followed by the wife a few times and she asks why I'm going so slow.  I'd like to buy a front tire which has a little larger diameter to help correct the speedo.  I definitely don't want to go the other way.

Same theory on the rear.  I'd like to get a tire with a little larger diameter to keep the rpm's down a little. 

Even within the same tire sizes, I see specs that seem to vary by 4% or so on how many rev's per mile.  I don't know how accurate the specs are, but after all they are specs so shouldn't they be accurate?

That was the first I've ever heard of it.
Looked it up and sounds interesting.
Do you do much mountain driving?
How aggressive do you ride?
What are your impressions?
Did you have your speedo recalibrated?

No need to recalibrate the speedo as it is driven from the front wheel. The speedo error all but goes away if you switch to the 130/70-18B "Wing" sized front tire but the tire is a big one and makes the bike handle much slower and "truck" like. This is only an option on the later model Concours with the wider 3.0" rim that is still too dam narrow to properly fit a 120/70-18R tire.

Steve's 7th gear is great for taking the buzzy edge off the engine at interstate speeds and you absolutely will not notice it in the bottom end performance unless you are already out riding the bikes performance envelope. I have Steve's gear change and find that the engine just feels more relaxed and at ease with itself at speed other than that it is hard to tell the difference.

I'll second Roadhound's recommendation on the Avons; I have those on mine and the bike is so nimble and responsive it feels like I just carved 100lbs off the weight; yet they are not touchy at all.
