Check the sticky's for the decompression mod, these will tell you what you need to know. In my case I took the fitting on the head out and fitted a plug.

As for the exhaust I cannot comment.

I've never read anything that said the YZ450 exhaust pipe will fit the YZ426. Regarding the plug, I've seen guys post about buying one of these plugs from ebay.
