Hi it's the new guy with a question?
Hi I'm Mark from Minnesota and yes now is a good time to be buying a Kawasaki.
I'm in the market and found one I like, but with one issue.
I take the bike up to 20-40 miles and hour and it's fine if I'm holding the handle bars.
If I hold the handle bars loosely the handle bars go from a mild to strong shake with in 2-3 seconds....
I look down at the wheel and I see no wiggle in the rim and the tire is at the correct pressure. Has anybody ever experienced this...?
Would the tire being out of balance cause this? I've owned a lot of bikes but this is the first one that did this?
1980 KZ650 E 58000 miles Starts and runs, with aluminum mags.
Wobble comes from the front tire When riding it at thirty to 50 I don't notice anything until I hold the handle bars then immediately, 2 seconds, goes from mild to wild in its wobble. Grab the handle bars again and your fine.
I like the overall bike, I'm thinking it could be anything from tread separation, out of balance, wheel bearings, I'm going to take a look at the bike again this week. Lift up the front wheel off the ground and see what happens. Any imput on what to look for would be greatly appreciated.
Thanks
Mark

Check the stem bearings while you are at it. Normally, the loose stem bearings, the choice of tire and mileage after a certain suspension setup are killers. But, of course that is "generalized"

Hey Mark from MN. Welcome from Warren in MN. Strange you mention that, I had a KZ750 years ago for a short time that did the same thing. Only when I let go of the handle bars. Never did figure out what it was.

Replace the front fork oil. The vibration is from lack of pressure against the wheel to the road. Most new bikes call for fork oil replacement every 20K. On older bikes, it's every 10K.
Fork oil is like any other oil, and breaks down over time.
