Yz Exhaust cam swap

Changing my 05 WR 450 to YZ specs, do I also need an intake cam or does the exhaust cam alone help to make it more like the YZ? I am converting it to mx trim.

YZ exhaust cam is all you need from the 04 or 05 year cam ( less hit than the 03 cam). You will need to reshim for clearances. :applause:

read few threads that used the stock cam with yz timing.

You will lose the auto decomp feature unless you guy the YZ exhaust cam! :applause:
