Referring to replies #4 and 5 I found two exhaust valves at minimum, one slightly tighter and one slightly looser at 12k miles. They have not moved in two checks since, the last at about 53k miles. So yeah, the first one is critical.
BTW, this bike is ridden and flogged quite hard in the fun stuff. The engine really seems to like playing in the 6-9k rpm range and so does the owner.
Yeah, if you want true ram air tuning, you better be willing to ram some air! (SteveinSunnyFlorida)
