I went ahead and pulled the regulator (if nothing else to get the old fuel out of it) I pushed about 40 lbs air through it just to make the diaphragm (or whatever is inside move)
Everything seemed fine, I already had the fuel lines, the existing were very solid and might have lasted another 30 years, but it's a cheap insurance policy. I inspected the breather, but didn't pull it, looked great until I got everything back together then I noticed some slight cracking on the left side so I will replace that later.
The injectors didn't look too bad, but sitting with old gas that that long I just replaced with refurbished to make sure.
I will carefully check the inside of tank during cleaning and before I put in the new lines,pump, screen etc. everything I ordered from beemerboneyard came right away, the few things I sourced from the local bmw dealer is a week out, water pump seal etc.
Thanks for the info on the alternative regulators, Oem online was over $160.00 so the alternative is the route to go.
The original fuel pump may be good, I did not test it, the original injectors may be good or could be refurbished, if anyone really needs them for their bike and are within the states I'd be happy to donate and mail them by USPO
