depends on the engine type. If the engine is a cast iron sleeved cylinder I would not run the Wisecos. If it is a nicasil (spelling?) coated aluminum bore then I would not worry about it. Aluminum heats up and expands MUCH faster than iron, and the cold seize syndrome is way more common in those engines, where a guy starts it lets it idle long enough it wont die when he slams the gas, and goes screaming wide open across a field. The pistons expand faster than the bore and it seizes up!
With the nicasil coated bore the metals used in both the bore and piston are certain alloys of aluminum, and will have a much more similar expansion rate, I chose Wiseco for my Liberty 600 after lots of debate about this exact same topic.
