I purchased a Works Connection skid plate and installed it last week. It was an easy installation using the 3 bolts from the stock skid plate. The skid plate fit perfectly and looks excellent. My problem is that the first time I rode on the track with this thing installed, I thought something was wrong with my bike! It sounded like a bike with 300 hours and worn main bearings. (Its an 06 YZ 450 with 6 hours use). I went back to the pits, took the skid plate off and then the bike sounded totally normal. Has anybody else experienced this problem? I would like to use the WC skid plate but do not want to ride a new bike that "sounds" thrashed. I think the aluminum was somehow magnifying the sounds coming from the engine.
