When were the clearances last checked? Over on SVRider, the greybeards there say that on the SV, the clearances actually WIDEN by one thou or so when the engine is warm. Seems counter-intuitive, I know, but that's what they have found.

Also, is the front header snug against the exhaust port? If there's a small gas leak that can make an odd sound, and that will stop when the engine warms up a bit.
