you don't have to have any thing done to the valves. that doesn't happen until 11-12000 mi. i think. the ticking is normal...my '05 does the same thing. also, MOTO JOE seems to have a lot of answers about that kind of stuff. i think he is a shop mechanic. at any rate he knows a lot of stuff.haus en heimer said:do you have to do anything with the valves at 600 miles like the katana? My bike tends to tick when idling. It has about 1500 miles on it. Is this normal?
