Hi all, I've just bought a 5 month old 07 450 EXC. It came with the motard wheel kit and the previous owner had ridden it (to work mainly) for 25 hours and 1,400 kilometers. I've ridden it off-road for three hours so it has a total of 28 on it now. I changed the oil in the weekend and to my dismay found the oil in the drain pan was glittering gold! Very small pieces (1mm or less each) and lots of them. It appears to be a plating of some sort as it's gold on one side and silver on the other and does not stick to a magnet. As well as being in the pan they were stuck all over the bottom screen. My local dealer here in Auckland, New Zealand thinks it's most likely to come from the cage on the big end (con-rod) bearing although there's no knock or any other unusual sounds coming out of it at this stage, and quoted around $2,000 (NZD) or $1,400 (USD) to strip and rebuild the engine. The 2K does include mains, rings and a few other bits that would be silly not to replace while it's all apart. Does anybody have any thoughts on this? Is there anything else that's gold inside an 07 RFS engine? Anyone had this same problem at this early stage (or at any stage)? To say I'm gutted at the thought of spending 2K this soon would be an understatement.
