Hi Hal,
Often the valve seats aren't cut at all [no 45 degree angle]. And many had a very small area cut on the seats. On all the cylinders, motors, or cylinder kits I have sold I always re-cut the seat with a NEWAY tool, then I lap the valves into the seats, then I liquid test them. If the dealer offered to re-seat the valves in the deal, sounds like he knows what he is doing, and you might want to consider buying the bike. On most [not all] of the bikes I have sold I upgraded the tires because it doesn't cost much to use a better grade of tire.
Have fun,
Quenton "Lee" Guenther
