Good question Ezduzit... wish I could help. Someone will be along shortly though, so here's another bump..
Here is the thread on how to "adjust" the valves.
The first post there has the thread on how to "measure" the valves.
Good luck!

Thanks for the link, this is above my skill set!
Yeah I am pretty handy and there was a lot to watch out for.
I just hope it is not "above the skill set" of who you take it to.
Best of luck!
Here's the link you want.

Checking the clearances is not that difficult. I just checked mine BUT I already had the airbox and throttle bodies off.
I have 15K miles and mine they were OK. Every post I've read say they these bikes generally don't need adjustment for at least 30K miles or more without adjustment.
I can do the routine stuff but this is a lil to much!
