Bad Tank slap
Would love to get some ideas on what could be causing the front end to wooble badly at speed between 25-55ish. It seemed to happen all the sudden, pulled bike in garage(felt fine) hopped on it for a 80 mile ride to work and almost right away i felt the bars shaking.
Ive checked tire pressure, greased the neck bearings...maybe threw a wheel weight??? Im gonna take bike to Harley next few days but open to suggestions till then.
Thanks

First thought is loose spoke's.
Check the following too:
*Wheel weights
*Check wheels to ensure they spin true.
*Torque to spec: pulley, rotors, calipers, axles, neck bolt, fork spring bolts, fork pinch bolts
Remember the issue could be on your rear wheel, so don't overlook it.

I normally do my own work but got a service almost due, tempted to let dealer figure it out.

It's a Springer so it could be many things. What's the mileage on the bike SINCE the front end was serviced? You need to check fall away, neck bearings, and the rockers. The fall away should be checked every 2500 miles. Mine has YET to be off. I need to but the tool though, because one of these days it WILL be loose.
Get a pencil or a piece of wood and check the spokes on the front and rear. As you run the pencil across the spokes the will make music. Ding, ding, ding, TINK. That would be the loose spoke. Even in the rear it can cause a wobble in the front.
Other things have been mentioned. Checking the tire for true, wheel weights, air pressure, etc.

RIP... thanks for the info. Dealer did the 10k service on it(March maybe), and im just over 15k now. I'm hoping i just threw a weight or something cause like i said earlier one ride it was golden and next it had the wobble.
Last week I had a SUPER slight wobble. It was so faint you wouldn't have felt it, but of course I did.
It was a lose spoke on the rear. Didn't even turn 1/8 of a turn. Rode it, smooth as glass.
Wheel weight is possible. Can't remember if I said that before though. I'm sure I must have... Lol
