[QUOTE="torch, post: 1458110, member: 1295"] Recently I have had a head shaker wobble if the handlebars are released at low speeds -- no problems at highway speed, no problems with at least one hand on the bars, but an increasingly violent head shake if both hands are removed. I checked all the fork alignment and adjusted the steering head torque with no difference. I attributed it to the worn tire which is approaching the end of it's serviceable life and started shopping for new shoes. I didn't remove the wheel and check the balance because there seemed little point if I'm changing the tire soon -- I'll balance things with the new rubber. Then the other day I was washing the bugs off and I noticed one of the left front axle pinch bolt heads was sticking out slightly -- it was loose. It's partner was barely finger tight. On the right side, one bolt was missing and the other barely more than finger tight. I replaced the missing one and torqued everything down and whadayaknow: the wobble is gone. I can't say that I've seen this mentioned before in the multitude of wobble threads, so add that to the list of suspects: check the torque on the axle pinch bolts. [/QUOTE]
