Hey guys,

I've recently purchased a 05 crf250x and noticed a loud noise coming from the top end. It looks like it is the auto decompression thing. From the 2 videos (linked below) does everything look good? When riding if I am low rpm, the top end makes a horrible noise but it seems to go away once I open it up. Any help would be greatly appreciated! Also it looks like it is running aftermarket cams, HotCams it says on them which I presume isn't standard.
