Earth moves very fast. It spins (rotates) at a speed of about 1,000 miles per hour and orbits around the Sun at a speed of about 67,000 miles per hour.

It's a wonder we can stand up at all.   :)

Around 1000 mph at the equator. The farther north or south you go the speed is considerably slower

Well, the whole planet is turning at .00069 rpm regardless where you are.

At my latitude, its ~796mph. Makes me light-headed thinking about it. :crazy2:

we are definitely slower up here in the north

Yes. But, rpm and speed are not the same thing. Speed has to do with time and distance. Close to either pole the time for a revolution is the same but the distance is far less

 I'm constantly teaching this to my machinist students.  RPM is frequency, speed is measured by distance traveled in a given amount of time, also known as velocity for you ballistic types.

DAMN. But you said it :2funny: :2funny: everyone thinke we southerners are slow but we want y'all to think that. Just so you will stay away :roll:

For us few that live at higher elevation,  is the speed faster because we stick up higher than those living a sea level?

Yes. Speed is a function of rotation rate and distance from the axis. Although, a mile or two more in elevation is but a tiny fraction of the 7000-7900 miles most of use live from that axle.

Dang, I didn't understand this entire thread till now.  ???

Same here I thought it was all about miles per hour versus RPMs ;D

Or, the OP has an issue with the rather aggressive stock lean when on the stand.

Being somewhat inseam deprived myself, it was starting to hurt my lower back, pulling the bike up off the stand. I bought the Rivco stand pad and, after a little grinding and filing, got it to slide snugly onto the stand. It didn't help much. Later, I cut a piece of synthetic deck board to shape, tapered it toward the bike side of the stand so it would rest flat, then threaded holes into the Rivco pad to take six screws. Drilled and countersunk matching holes in the deck board, so the screw heads were recessed some, and mounted it. I ended up adding about 11/16" at the inside end of the pad. The bike is much easier to stand up now, without straining my back.

Yeah my bike leaned so much I actually measured it it was 24 degrees (yeah I'm a machinist), and the sidestand wasn't bent nor was the mount bracket either. I think they just made Valkyries lean way over in case both tires went flat? that's the explanation some have proposed. At any rate I made my own little pad to go under there out of aluminum and it jacks it up about 3/4 of an inch which is about normal I think for a motorcycle to lean

I recently learned that the magnetic North Pole moves around so much that airports at northern latitudes need to renumber their runways from time to time.  The directional survey tools used to determine the well paths for oil and gas drilling also need to factor this into their calculations.

For years, I thought there must be something bent on my '97 R&W because everyone commented on how much more it leaned than everyone elses. I thought maybe the Austone taxi, but another friends with an Austone Taxi doesn't lean as far. Maybe shorter kickstand? Nope, replaced it. Same amount of lean. Bent crossmember? Nope, straight as can be. Plus, bike had only 2500 miles on it when I got it. Then, on a recent trip from Oklahoma, a friend bought another '97 R&W just to ride home with me  :angel:. It was manufactured on the same month as mine. Leans exactly the same amount even with stock MC tires. Yup, some of them were just made that way.

My 97 r/w leans more than most other valkyries I ride with as well

Lean can be impacted by either the height of the tire or the length of the shocks.

I have two 99 interstates.  One leans noticeably more than the the other.  No bent cross member or kickstand hardware (and I really looked), or kickstands.  Identical shocks and tires.  I had put the chrome kickstand on the leaner, but it's identical to the OE.  

It's no big deal to lift the leaner (it is more work), but I switch bikes every 4-5 months (not weeks), and when I take the leaner out again, I think I'm dropping the bike when I throw it over on the stand for the first few rides.  

Hook#3287

Yeah, but looking from the front, lean right. :)

Yeah I run stock tire sizes front and rear and I still have my stock shocks, but I've read that some Darksiders have a little bit lower tire height so they don't lean as far.

Not only the the brand of the shocks but their setting can impact lean.
