Welcome home Mapper.
I live in Fairfax County, and have used a master mechanic named Casey Harrington down in Stafford for both my Valks for years, and he is top notch (works on all makes and models). One man shop. He had his own shop, then was the lead tech at Coleman Powersports in Woodbridge for some years, and then went back to his own business. He is always swamped during the riding season, so you may have to wait a bit.
This is his simple website.
https://ll7cycles.com/ He recently moved, still in Stafford, but hasn't been able to get his website changed to reflect his new address yet, but the phone number number is the same. It's 31 miles for me, and absolutley worth it.
His new address is
80 Wyche Rd, Unit 201, Stafford VA - 540-602-0380 Map to new shop.

EDIT: BTW, when I have had him change the rear tire and service the final drive, I've asked him to pack the shaft/splines/pinion cup with good grease, even though the Honda manual says only to lube with some (a little) moly paste. He was happy to comply, and of course I've had no further wear as a result. I do get some grease thrown out afterwards, but it cleans up and doesn't keep coming out.
