Bought one after Irene, paid $506 final otd price. Works great at the track. Runs all day on one tank only turning it off while out riding. It is a little bigger, heavier and louder than a Honda, but still acceptable. It has a luggage-like telescoping handle to tow it around which already broke, but its light enough to carry like a suitcase. Only flaws i can see is when you need to store it, you have to dump any remaining fuel which can be messy. There is a drain screw on the bowl of the carb. idk, a petcock would be easier to hook a hose to in order to drain fuel. There also isnt a drain plug for the oil, it also gets dumped out, then you have to wipe up the mess you made. The service interval is 100 hours, which seems long for half a quart of oil. Otherwise, works great so far
