I blew an engine over New Years weekend in my '03 M.C. 900. Needed a new crank, piston, cylinder among other things. Dealer I use never really had a sure cause to point to. Oil pump checked out and worked fine at the shop. Almost $3k later I had 'er back and was impressed with the power. It was like having a new sled again. Took it out for the break-in ride and put around 60 miles on it and was careful not to over do it, opened her up a little bit along the trail and did a couple small climbs. Nothing too stressful. Called the dealer and said how the ride went and they said I should be good to go and could ride how I want. The oil resevoir was just over half full so I thought all was well. I topped it off for the next ride. This past weekend I went out for the second ride on the new engine and it seased up again! I need a new crank, piston, cylinder, yada yada again! I'm not shelling out another $3k. Checked the plugs and they're the right color but totaly dry, the right cylinder was shot, broke off the arm and beat up the crank pretty bad. Both pistons and cylinders were dry and oil free leeding us to believe I had a bad oil pump. Do you think this just miracurasly happened between the first and second ride on the new engine and I have the worst luck, or should my mechanic have replaced the pump? I realize hindsight is 20/20 and I shouldn't be an armchair quarterback, but I'm at wits end and to say the least a bit frustrated. Below is what a new piston looks like with less than 100 miles.
