Well after A mere 20 days Interstate Cycles of Cornirlius North Carolina came through. I must say these guys really came through. When Aprilia couldnt find there way out of A wet paper bag The dealer took it upon themselves to remove the engine from A brand new 5.5 and install it in mine. I told them that was not nessasary but they did it anyway. The bike runs like A top, starts better than before,idles better. Aprilia needs to take a hard look at Interstate Cycles and maybe learn a few things about customer support.
