In Oct purchased new MX800x as a gift for myself after separating from supposedly better half(HA). Because of low snow conditions and work schedule never got to ride 'till yesterday. Left the Snye with a buddy of mine on his 97 Formula 500 Deluxe. Weather was -18C, sunny and we ride about 800 ft elevation .Dealer told me to ride unit in all throttle positions for about 3 hrs to ensure good break-in. Doing about 90k's behind Lenoard when the machine began its death throes. Seized solid. Towed back about 40 k's, tossed it in the back of my truck and off I went for a 3 hr drive to nearest dealer. There we removed y-pipe and found mag piston destroyed. Top half of crown, skirt on exhaust side gone either out pipe or into crank. Looking at a 3-4 week wait but in meantime they did loan a Formula S , 380cc of fan power! Look out now. Anyone have ideas? Know of a number ot Bombie I can call to #####, I mean talk, too? Also, yesterday I was informed of the carb updates but they said it was intended more for higher elevations. Other than a x's hex, any thoughts? A missplaced match sounded good for awhile to me.
