Wheel Balance

I've been going on some 2-3 hundred mile shake down rides in prep for the Western V-Strom Rally. Iv'e noticed a bad shaking in the front above 75 mph, think of HD shake. It's hard to look down and see if the front wheel is bouncing at 80 and stay on a good line. When I would take my hands off the handle bars would shake so bad I couldn't read my GPS. I figured it had to be my wheel out of balance, I looked for signs of where wheel weights fell off, nothing. So I took the wheel off and down to the local dealer to get it balanced. It took 7 oz in one place to get it balanced, thats almost 1/2 lb, how could the wheel and tire combo be off by that much?

Couple questions:

What type of tire?
How many miles on tire?
How many miles on bike?
Did they rotate the tire 180 degrees on the rim to try and lessen the amount of weigh it takes to balance?
Did they check the wheel itself to see if it's bent?

That is a lot of weigh, and somethings not right somewhere to get that type of "bounce" at speed.

BTD.

I wonder

I wonder if the dealer attempted to find the heavy spot on the wheel and the tire independently, then positioned them opposite each other? I don't suppose, since that would require pride in your work to the exclusion of profit. Certainly each could be out 3 or 4 ounces, and the heavy spots ended up next to each other. If you had a friend in the service department, might be interesting to balance the wheel by itself, then try orienting the tire in different places (rotationally on the rim) to determine the heavy spot on the tire. Practically speaking, it probably doesn't matter, since the wheel/tire is now axially balanced (and hopefully laterally balanced). The idea of minimizing imbalance by orienting the tire correctly is only of value if your wheel weights happen to fall off or get knocked off.

I would either find the cause of the issue or trash both the wheel and tire! Yes, I know that's an expensive outburst but something is very, very wrong there. No way you should be 7 OUNCES out! Personally, I wouldn't put my faith in it when the most important tire on my bike is 7 oz's out!

You might have bad wear on that tire but step one is to be sure that your wheel is ok, balance that without the tire and see how it turns including checking the runnout. Then look the tire over for even wear and be sure it feels nearly the same rubbing your hand clockwise and counterclockwise. If this started all of a sudden it sounds like you lost a weight but 7 oz's of weight all at one time? No, I don't see that happening without you taking notice do you? Check that wheel really well and see what you find.

Good luck!

Tourance tire, about 5000 miles, 14,000 on bike
The wheel is new, tire wear is fine, still has about 4000 left
I haven't put it back on to try it yet, the balance was free, this dealer has great support.
