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?
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.
btw- I always try to balance the tire with it on the bike....the same as it is when I'm riding it!
