How many of these things are out there running? I don't want to be the guinea pig so untill I see one or see some feedback I am hesitant. I have seen a couple of the saitos and would not go there on gasoline as I don't want to have to run that much oil as the rods are not on bearings.. I have had a couple of saitos eat exhaust valves on glow- course that was after a lot of hard running..
