just traded for a `06 400ex and there is a slight rattle in the topend that goes away when it warms up for a few minutes ive narrowed it down to the decompression mechanism is this normal i have nothing to compare it to cause me other 2 ex both have hotcams in them so no decompression mech. it only does it when motor is completly cold and after a couple min its gone.
