A Wobble Question
asks.........
I posted this question on a harley tech talk site, so I thought I would ask it here.
Riding back from Martin, Tn. on saturday from a PGR Mission, coming down hwy 51 ( big divided 4 lane). Thought I'd let the horses loose, since there were no traffic in either direction, and I could see a good 3 miles ahead of me.
As I got up to about a 105, I began to experience a gentle side to side front end wobble, taking it up to about 110, the wobble began to increase slightly, but still manageable. I rode along at about 108 for 3 or 4 miles, and the wobble was constant. Let her coast down, the wobble began to fade away, and was gone completely at about 100.
I began to ponder, what are causes to make a front end to react like this at high speeds. In the four years of owning this bike, I have always been able to bring it up to 110 - 115 without a wobble issue. So I will put it before the talent in forum.
What are the LISTED reasons that would make a front end Wobble at High Speeds over a 100mph?? Please no smart a$$ remarks about not riding at those speeds. If you can't contribute anything but off handed, wise a$$ed, or off topic comments, please do not reply to this posting.
Thanks in Advance....

Tire wear,road surfaces,fork oil,fork springs,wheel balance,WHEEL BRGS,ftr to back tire alignment,could also be soething you have added on recently-wind deflectors,taller shield-.Batwings arent very aerodynamic at that speed.

RE: A Wobble Question
True Track is a site sponsor, I'd give them a call, they know lots about the HD suspension and causes and corrections. Their phone number is 818-623-0697. If you go to their site there is a lot of page clicking to get to the number. Give them a call let them know you are from HDforums and I'm sure you will get your dimes worth after talking to them.

RE: A Wobble Question
If you have a batwing or windshield, that may be what is causing the wobble. If not, I would check the steering head, wheel bearings and front tire.

I am going to start with the easy stuff. Pull the front wheel off and check the balance & bearings. Then I'll check the steering head, and work my way to the back of the bike. Appreciate all the input! More than I got at that other place,

RE: A Wobble Question
I know your starting at the front, which is all good, but don't discount the rear. At those speeds a rear wheel can throw it into a wobble also. You might check the spokes if you have them, I incountered a wobble once only to discover that my rear wheel had five broken spokes in it. Just another thought.
