OW! My aching back!

Off on a tangent is half the fun.

Another suggestion (concerning the back) is a rider seat back. I installed one on my V-Star and it was like night and day. I have a bad lower back to begin with (from an auto accident) and was getting some pain. Installed the seat back and now I can ride for hours without any pain.

Lynda has a rider's back rest on her M-50 and it makes a long ride much better. I have one on the Vstrom and it is a great addition for comfort and stopping back pain.

Just walked in the door 30 minutes ago...a little over 700 miles today.

Left Sanford,Fl at 7:30 got home at 7:00.

One bike in our group of 4 could only go around 130 miles before fill up.
We had plenty of gas breaks.

No back or butt problems on the trip.

JWR, just did the math. You guys weren't just out for a relaxing cruise.

[JWR]

You got that right...

Suzuki TL1000 was the short mileage bike.
Honda VFR 800 was next.
My SV650.

The gas mileage king was a Yamaha R1 1000cc with 82,000 miles on it.

He beat me by 1 tenth ever time, but I was turning over 7 grand and he was doing 6.

Speaking of a 'fast' crowd, I will go off on another tangent with some questions concerning speed: What is the formula for determining engine RPM for various speeds if one knows the drive ratio. The owner's manual for my Shadow lists 'primary reduction' of 1.763; 'secondary reduction' of 0.944; 'final reduction' of 3.091; then the gear ratios with 5th gear being 0.852.

I would like to know the RPM's at 55, 65 and 75 mph in 5th gear. Also what is the highest reasonable RPM for a 745cc V twin that won't damage the engine?

I am simply trying to figure out what the best highway speed is for my Shadow Spirit 750. I feel she should do 65 fine, but I also feel the engine getting up in the revs at that point.

Do a search and find a Honda forum with 750's. You will no doubt find many threads with subjects concerning RPM and speed. That would be even easier than burning up a calculator with no real world comments from owners. You may even get tips about higher criusing speeds and the comfort level of the bike at those speeds. In all likelyhood the bike is stronger and has more endurance than you have.
Last year I spent a few hours travelling with a new friend on a 750 Honda. 60-65 MPH was a comfy speed for the 2 of us but he may have ridden faster when alone. OR he may have ridden slower.........who knows. He was happy and smiling with the bike and the open roads.
We were on secondary scenic highways that had enough curves to be pleasant but safe at those speeds. Paradise on 2 wheels eh !!

To get back on track and answer the question of my OP: It was my kidneys telling me to DRINK MORE FLUIDS, STUPID!

I have had some minor kidney pain in the past from not drinking enough water, but never as bad as this. I guess it is just part of getting older. It has taken a couple weeks of drinking plenty of water for the pain to almost completely go away. I still get the occassional very slight twinge, but I think the problem is about gone.
