do you have your rear tire perfectly straight? I run dyna beads to help with balancing

Perhaps the front wheel is out of round. I suggest you elevate the front wheel, and spin it to check for trueness.

maybe a loose triple tree, or wheel bearings are shot, maybe

Unfortunately I don't have a picture of the truck. 1970 F100 under going a body swap due to rust.

Engine:

Forged crank, H rods, Mahle +60/1000 pistons so it's really a 355", Ford Racing cam, Edelbrock big valve heads, Edelbrock Preformer manifold, Demon carb, full MSD ignition, long tube headers, 13 quart pan, built AOD transmission, 4:11 posi.

Sounds dangerous. Could be any of those things previously mentioned. Everything should be tight and true (both front and back), evenly worn tire, enough air pressure, etc. Check all bolts and bearings. Check sag.

If there's been any departure from stock components, check for variations from stock geometry. ()

Good luck. The good news is that it's not endemic to the bike; mine is solid at 90 on asphalt and gravel/dirt.

Check your steer head bearings. Adjust as needed.
Try a very high air pressure like 23 to 27 PSI.

Although, most of the tires I have used do the wobble/head shake thing.
Exceptions have been the Dunlop 908, the Metzler Unicross, and the Michelin Desert race.

Now that's fuzzy math.

New 606? Mine was scary until the sharp edges wore down.

Cali Ban on GPS apps

I don't know how many of you use the dualsportmaps.com app or MotionX for GPS routes, but apparently California has banned the GPS apps on phones...

Doesn't matter to me. I still talk on the phone and text while driving. Driving is #1 priority. Everything else is second. I'm in the minority however.

I was on a wide gravel road with 18 other riders, standing on the pegs so couldn't use my mirrors. Had a truck fly by and nearly clipped me with his mirror.

Are they banning having the app running, or futzing with the phone?

Of course if you are on a bike why the hell would you stop anyway...
