Mark, does it scrape before boards in corners?
Alan,
No it does not, the boards will scrape before the arm. Trapperdog (Roger Lane) and I are practicing for a Police/Civilian motorcop rodeo in October. Right now we are working on police courses set with 18' circles and U-Turns. I am really leaning my bike waaaaay over to clear these courses. So far I have only scraped my boards.
You have a StreetGlide, which if I'm not mistaken, comes lowered from the factory. If you order one, make sure you tell them this, otherwise you may have clearance issues.
Are you coming to Cody/Yellowstone?
