i bought the 1300 last week in black, im a big fan, kinda jumping in the deep end though never having a road bike, but within 15-20 mins i was doing 50mph+ comfortably, as for the valve issue i have buddies with crotch rockets that have this issue, and they never go on the mfg schedule, 1 friend told me he does it once a year and its never far off,well withing not adjusting it, and thats on a hayabusa you know 17000rpm range and he has 12k hard miles on it, have fun and be safe
