Hi im sorry if this topic has been talked about already but I am new to thumper talk.
I have a 2000 Wr400, and my friend has an old set of 2003 Yz450 cams he gave me to make the auto decompression swap.
I have read all of the articles on making the 400s auto decompression and i feel confident in making that swap.
My Queston is, Can I swap out both cams, the exhaust and intake?
Wondering if anyone has done this and what the results were.
