Its been known for them to develope a crack in the cylinderhead between the valves. Well thats what I was told when mine did it, then again it had done over 70k, so it was replaced with a XBR head that had the squish machined out to suit the 700cc Wiesco big bore kit that went on it, along with Laser Produro exhaust and in the wnd 17" alloy 3-spokes.
There is a dead one sitting in Dallas's garage at the moment, running them out of oil is not a good idea
