Ok, this is my 3rd KDX and I should be use to the power valve noise by now, but.. this is my first NEW KDX and the power valve is louder than the other two used KDXS' I owned (1990 & 2000) My new KDX 200 2002 "leftover" seems very loud I mean, like it just don't sound good. Is this the norm? It just seems to rattle a lot. Thanks!!
