I assembled the main gear fairings per the manual. I have one issue related to the optional bush tire set-up. The wheel/brake assembly is wider (deeper?) than the stock unit causing a clearance issue with the lower end of the fairing. The end of the stock fairing protrudes into the brake rotor "dish". It has about 1/4" to 1/2" clearance from the rotor, but I am not certain if that is sufficient. I am looking for photos of a stock fairing to try to get some idea of the clearance needed.
