Babyhog, there was a large extended cab Ford superduty parked beside me blocking the second half of their approach view (where the bike was hiding) and I think they just whipped into the "empty" parking place and got a surprise about half way in.

Remember your high school physics, Conservation of Momentum transfer from a large vehicle to a small one.

Mass*Velocity = Mass*Velocity

3,000+ lb vehicle at 5 ft/sec = 300 lb bike at 50 ft/sec.

You remember the pendulum lab, the big ball smacking a small ball and it moving faster as the energy transfers through the m*v relationship.

In short, they weighed a lot more and weren't going that fast, maybe 5 mph.  My bike got the equivalent hit of an equal weight motorcycle going 50 ft a second (and in plain English that's about 34 mph)

In reality, bumpers normally absorb some of this energy -- but my bike didn't weigh enough to cause his bumper to give very much.  My tail light / liscense plate assembly did most of the energy absorption until it mashed in to contact the tire, then the tire, wheel and axle/swingarm took the rest of the lick.  Then the side of the bike and the front wheel against the curb stopped the bike from sliding.

Words to the Wise

Always avoid getting hit by a car.  You see videos of bikes getting sprayed into air born pieces when a car hits one at any decent speed -- this is why.

You Gonna Have this thing worked out by June 2010?


DRAGON RUN

Did anyone declare any form of fall trip that you know of?


Not really........... I'm back at school 3 nights a week and working 40+
and kids are back in school too.... no much time for riding except back and forth to work and school.....

might be worth a try of collasping the tire and reseating it.

Justin, the bead line is straight and the sidewall of the tire itself has .025" variation measured at the same time I was truing the rim.  There is nothing gross or "out of spec" about the way the rear tire runs to Suzuki/Clymer book specs -- but the variation of the contact patch is enough to give skidding variation and is enough to play in causing the current rumba/wobble issue.  It is mild enough to be succeptable to wear in though.

Update wear in report:

I noticed that I hadn't noticed anything in the last few days and went and took the bike up to shudder speed to see what was what.

Tire is wearing "rounder" and the wobble issue has become pretty much un-noticeable during normal weekly use.  If you take it up to the critical speed and dwell there you can get a mild wobble, but you are having to pretty much work at it to get it to happen.

I think this thing is gonna cure itself given some time and tire wear.

Thank you (GaryonaSavage and others) for all the help and sending of bits and pieces guys, it is just another good example of the list doing good and helping each other out!

  I would fine some really big bumps and go over them and maybe the frame will flex its self straight.

free frame you say?
