Bob,
Did you notice a difference on the bike in how it handled?

Stock ones fit noticeably looser than Nichols.) Front bolt had a nut on the right side so did not need the frame drilled. Rear bolt was screwed into the frame so needed to be drilled out with a 13/32” drill bit (0.406”). The Nichols titanium nuts do not show from the frame equally on each side in order to have equal thread and grip on each side, so use of the Nichols provided gauge is recommended."
In order to insure I didn't booger up the frame drilling I made a guide to hold the drill bit steady. Also, I had to get a new drill because my old one would only take up to 3/8" and the 13/32" size wouldn't fit.
Overall, the quality of the bolts with their titanium nuts is outstanding. I was surprised how easy it was to remove the stock bolts and more difficult to install the new ones. 6 thousandths really makes a difference. I'll try to ride this weekend to evaluate. All in all a fun and easy project.
