had something similar happen to mine when i put it in for 6k service,3rockers and 1 exhaust cam(748r).DUK paid for cam and half the cost of the rockers.bike is a 2000 748r,full DUK service history.worth giving their warranty dept a ring as they were helpful.
no the feeling as i had to wait 2 months to get my bike back as noone had the cam in stock,not even the factory!!did make me wonder why i gave up my Marlboro R6 until i picked it up and rode home
.hope you have some luck
