The wobble I had before was due to the stem bearing. After having that changed out,k it was good to go.How many miles are on the tires? Vulcan's are known for this; as the tires wear it often happens. Some say it's the angle of the front forks that causes the tires to wear in a slight cupping pattern, but you can feel it in the tire if you run your hand around the tread. It's subtle, but it's there. Changing out the tires is the fix.

This is a good time and good measure to do the Zerk fitting mod by adding one to your steering bearing area.

This is when i've taken my hands off the handlebars. I put my hands back before it goes to a tankslapper. Sometimes I have to take my gloves off to relieve carpal tunnel pain or adjust a flapping helmet strap. Tyre pressures are correct. Swing arm bearings replaced 10,000 k ago.
I'm thinking, in order of ease/cost
1 - jack the front wheel up and check free play
2 - remove front wheel and have wheel balance check done
3 - check/replace steering head bearingsWhat are the symptoms for worn steering bearings ? Do they start at just one speed
Any other suggestions. Thanks
i had the wheels trued and the wobble disappeared...however it felt like i was riding a horse. ended up changing the tires to bridgestone (from michelin commander II's) and viola problem gone.
hope you find it!

- November 04, 2016, 09:52:07 AMwhat kind of tire do you have? I had a similar issue with both my W-650 and my 1500 Drifter at the same speed. I replaced the front tire on the W from a Metzeler ME-33 to a Continental Conti attack and the problem disappeared. I replaced the worn out Michelin Commander on the Drifter with a Metzeler ME888 and the problem disappeared, as well.
