Great report, Greg, your bike is simply incredible!  Couldn't the bad spark plug cap be the reason for the sooty plug?

Thanks Stev-o.  Yes, no question the caps were the cause of the problem. I should have checked them out before this.

What speeds were you running on the stretches where you got 50 MPG?

I kept it 65-70 pretty much the whole trip to take it easy on the poor old thing.  We stuck to 2 lane roads most of the way, which generally are posted 65mph.  One leg on the way down was interstate from Burley Idaho to south of Pocatello to join up with US30 because of where we were headed.  That was 75-80mph.  Idaho interstate speed limits are 80 mph away from towns and I didn't have many people going by me.  Mileage dropped down to 43mpg or so on that stretch.

However, I am mercenary enough that the bike remains for sale, current price $160,471.30. 

I like your pricing idea! I might have to make that offer myself? Mine's not as expensive as yours, though, at only $149,567.40 it's a bargain.
:D

A bargain it is.  At that price, yours would sell quickly though, leaving mine again without any competition.

As usual, it seemed to run stronger the farther we went.

Mine has always been like that, too. If I ride it mostly in town for, say, a year, then hit the road/hills with it, it smoothes out on the 2nd or 3rd day and just begs for more.

Greg,  have you retired yet?  What were your three careers as?  Any more thoughts on a new bike for the collection?  Oddly enough the initial run of 750 DOHC motors were not that good, they must have fixed that as the Nighthawks have a cult following and I had considered buying one at one point.  The Nighthawk 650 was unreliable as they had punched the 450 design from original for the 550 and then the 650, it overstressed the motor in a few areas leading to failure areas and other problems.  They started over for the 750 Nighthawk motor with an evolution of that design.  I am not suggesting a Nighthawk as I didn't research their parts and other issues heavily.
It seem Honda has produced some rather mild perf motors in recent models with uninspiring perf.  The CB1000 retro throw back and the motors in the CB500 variants.  Both seem to have steady and rather flat power delivery and their output is far below what many would expect or want.

Sales in bikes are way down on most models with some exceptions.  So, it can be a good time as a buyer with a little bit of leverage when buying since they are wanting the sales.

Nope, still working for a living.  I now fantasize about pulling the plug next year.  Back when I was a young stud I built railroad cars which is where I picked up knowledge of fabrication, welding and machining, then retired from the FAA after 27 years, now working for Idaho's transportation department.  Still don't know what bike to get.  The Thruxton R is cool, but there is nowhere to pack any gear for traveling, plus fuel capacity is too small.  I rode a R1200RS and was very impressed with it, but it shares many of the characteristics that pmanning and I were grousing about in the posts last year.  The base version is better for that, but they are more elusive than Bigfoot.  There is more profit for BMW with the models with all the features.  I probably ought to just get a V-Strom, which is what I advise people who ask me for a recommendation.  But they don't float my boat for some reason, good as they are.  So nothing has changed much in the last year.

Greg........Are you planning on riding your 750 to next year's reunion? I just got a new winter project, a 1983 XJ900 Seca Yamaha. With 17k on it. Needs a little tlc and adjustments but in pretty good shape. However I plan on riding my 750F Honda to next years meet. Any ideas on where yet?

I'd like to.  There was some talk about doing something in South Dakota, but I think it fell through.  It just depends on where it is and how much time I can get.
