Must be a different KTB, mine has a table for UFM and Cylinder Head Bracket Assemblies. I guess what is puzzling is that KTB says .360" wire diameter for a 180 spring. My Bobber has a .360" spring. The high riding B has a .360" spring. So, the only other variable is the spring length which I can't compare as I don't want to pull the springs out of both bikes and have another 2 Vincents sitting disabled. I will wait until the spring from the VOCS arrives and then pull the high riding one out and compare them. This chinese flu has really put the brakes on transport. Its been 4 weeks since Michelle sent it.
