It's just routine to check the valves every 16K miles. Not that they will need adjusting.Yeah I really wanted to get the 2002 and up but budget held me back and the 01 was the way to go. Mine has 15k miles on it so it's all god I guess. It hasn't had the valve job done. Is that really a big deal with these bikes? I've had a 2001 Aprilia Mille and a 2001 gsxr600, 03 hayabusa that all had 20k+ miles and they'd never had the motor open.
