Sorry, I know this has been beat to death, but all of the info I found was on installing a YZ, not WR cam. So my question is, can I install a 2003 WR450 cam in my 2000 WR400, and will I have to time the cams differently than stock?

Thanks in advance, Davo

Yes, you can, and yes, you will have to time the engine exactly as shown in the '03 cam swap thread:

Thanks for the reply! Just to clarify, I will be using an OEM WR450 cam for a 2003. So time it as shown in the thread that you gave me the link for ?

Thanks, Davo
