maybe, just maaaybe your front wheel is busted (oval or needs
balancing) maybe you hit a pothole or sidewalk too hard and its no longer
perfectly round or maybe a few of your spokes are loose, just push bike to
the left on it's sidestand till the front wheel spins freely, then visually inspect it;
or just remove it and take it to a balancing center, good luck

...front forks need oil? engine brackets loose? there are about 6-7
of them, under engine, under battery box, under gas tank, etc

Definately in the motor. It's not the wheel either--rolls smooth at any speed. Rev engine in neutral or anytime I throttle it vibes. Engine mounts seem tight. I think it's something more internal, like a crank bearing or loose clutch assembly, or loose head bolts.

Yes they have. The idiots that messed up the clutch last summer--it went to dealer--he found all the stuff idiots did wrong--no oil to engine for 60 miles--had upper 1/2 of motor replaced by the idiots--have had slight vibration ever since--has gotten much worse this summer--have put on about 2000 miles since I got it back end of last summer. I don't remember it vibrating this bad before all the clutch and everything was done. While at dealer--he replaced the timing chain tensioner adjuster with the new updated version. I doubt seriously if they would honor any kind of warranty now, as I was given nothing when I picked it up.

Location? Might it have been boogered when the clutch was done or when upper 1/2 of motor was replaced?

Ever since last summers head replacement fiasco, I've had a vibration. Figured it was normal for a 1-lunger.

Hold it,....
If this didn't start till after the head work, how would you think it mite just be normal for a thumper ?

I know, you're not on trial here, but just curious when the vibration really did start, as that could make a big difference. Shocked

It did vibrate some before the clutch and head work last year--normal vibe for this bike. When I got it back, it seemed a little worse, but I hadn't rode it in 3 months, so I thought maybe it was normal. This summer, it has slowly but steadily gotten worse, to the point where I cannot ride the highways without hand numbing vibration. In town, ( 30-35 mph ) seems ok, although I can feel it in the footpegs, almost like a bad wheel bearing on a car. Still seems to run ok, doesn't burn oil, just vibrates a lot. Undecided

I have never tried it, but some have reported that filling the bars with birdshot will help. Use something like a winebottle cork in one end, lean the bike to that side, pour the handlebar full of birdshot, and cork the other end. Note that if you are one of the fanatics who want to eliminate every possible bit of "unnecessary" weight this might run contrary to your desires.

This is my second thumper...the first being an SR500 Yamaha, twenty years ago.

The same numbing vibration-caused tingling. FWIW, I find it's speed-related...had a bad case of it on a 50-mile speed run (had an appointment) today where I was ramming the Interstate at 80-82...wide open, top speed. Hands were buzzing for ten minutes afterward.

Three hours of more reasonable cruising at 55-70, couple of hours later...no issue.

Rather than rebound, it goes thud, absorbing the blow. fill half to 3/4 full.

As I recollect they would not have been into the counter balancer area unless they pulled the engine and split the cases. Max

Trying to read what exactly has happened, it sounds like this has gotten worse over time. Have you adjusted the valves lately? Valve clearances out of spec can make an engine run like it's out of balance/ out of time or in other words it'll vibrate. Never did see where you have torqued the engine mounts, to be sure of the proper torque, they should be loosened, and then tightened to spec.
