I've got a love/hate triangle going on with mine; but Al's friend is absolutely right about the "cold-saw" buisiness. They DO really need a lot more to warm up, but when they do, they have beautiful torque and (when modded) comparable (to the 200) throttle response. I did all of the Brad Sneller mods myself, just to be able to live with that pig. Can't imagine running one bone stock. The flywheel timing advance really seems to push it along a bit, and you definitely want to rip those silly, plastic limiter caps of of the carb screws, and drill-out the limiter pin. Hog a big hole through the muffler, and your done. Nice torque out of those pigs, even if they are cold-blooded SOB's.
Oh and Butch: If you don't want the pain in the neck of modding that thing, just (I'm actually dead serious here) ram a bar wrench through the side of the muffler with a hammer or something, and I SWEAR it'll run better than the bone-stock pig that it is.
