Thank you all for the suggestions! here's my slow progress...
1. new, soft, Superbike grips - and i hadn't realized how worn and thin my old ones were :/
2. covered them with grip puppies - the increase in grip size is great and they're really soft - i found the easiest way to install these is to: cut to length, roll them up like a... well it ends up looking like a doughnut, work the doughnut over the end of the grip, unroll towards the center just like a.. doughnut. Of course I did 1 and 2 at the same time, so I just have the sum, but it's far better.
3. steering head bearings - i replaced the original ball bearings with roller bearings about 25k ago and have checked them a few times since (once for a fork rebuild). the originals had a slight detent right in the center which is now gone and smooth.
4. bar ends - I imagine the rubber in these wears over time so they may be worth replacing. when i put pinky and ring fingers over the bar end weights though, they're-a-buzzin compared to the grip. I'll look into heavier ones though. I need to go through the manual and see how to remove them
5a. i loosened my gloves. i prefer gloves with long gauntlets but may have had them too snug. they're a little looser now but certainly won't fall off.
5b. i didn't change anything with my jackets, but i do pay attention to them more now and wriggle around if i notice any tension or tightness in my shoulders. also re-adjusted my backpacks a little
6. avatar description fixed :/ how many years...
So .. to do...
1. balance throttle bodies - it's been a while and they always need a little adjustment. I noticed there is a particular vibration at 4000 rpms, +- a few, i'm avoiding this range now and it helps.
2. re-balance front wheel - i need to replace pads anyway, so while i have the front wheel off, i'll balance it and replace the wheel bearings. this set of tires only has a couple thousand miles but worth a re-balance.
2a. same as above, i'll re-balance it.
3. I need to replace my gloves, the left has a nice hole in the palm. they're sedici so the exchange is free (frequent too) and i'll see if they have others with thicker palms
4. ugh. x-rings are burned out of my master link. chain/sprockets are only about 5k old but the master has to go. i do keep it lubed and adjusted
It's possible that one aggravation is that I always ride with my pointer and middle fingers over the brake and clutch. so they are always absorbing a little vibration through the levers. I might see if I can find a little sleeve of foam to cover them.
