I cannot as of yet ride the bike. It will need to be inspected by the Troop C Highway Patrol here in MO and then titled etc.
Here's what I have to work with. This looks like enough clearance, but the copper tubing on the inside takes up about half of my original clearance. Hindsight now, I would have moved the copper tubing off to the side of the center of the fender. The fender is flatter than the cross section of the tire, but alas, this was not in my mind at the time.
A half link would help me out, but for a 530 O-ring chain, there are NO offset/half links made. I even called Diamond Chain and they don't offer one. I have a Diamond O-ring 530 chain on the bike. I could switch to a non O-ring 530 pitch chain and "then" use a half link to adjust the tire further back in the fender just a bit.
I "may" be able to lengthen my lower spacer and then extend the fender up and rearward a bit with the offset upper fender mount adapters I made up to get where I am currently.
My thoughts were that if I went from 30 psi up to 65 psi and take the two measurements, that I would replicate a HOT tire with expanded pressure etc. Again, the tire radius only grew less than a 1/16" between 30 and 65 psi.
Thanks for the input so far, greatly appreciated...
