Had to sell my M900 a few months ago. I still miss it.

But looking seriously at picking up a Supersport 1000 or possibly a SC1000. I have a specific 2005 Supersport 1000 that I will be looking at next week, and possibly a 2006 SC 1000 the week after, and was concerned about bad valve guide issues. I've read that they are common with the DS1000 motors. When I have a looky at the SS1000, what might I notice with the engine startup/running/test ride that might indicate bad valve guides? Also, with VIN in hand, could I call a dealer to find out if that particular bike was prone to have bad valve guides? Both bikes are below 2000 miles, and both are being sold by non-Ducati dealers, and there is no local Ducati dealer where I live, so I would just be cold calling a service department somewhere randomly.
