The YZ cam timing is a simple procedure, and if you do not want to get the decomp cam, then you can use your WR cam, and do the YZ timing mod this weekend.
If you do not like the extra power (yeah, right ) the just put it back... costs you nothing except a couple of hours of your time... you probably should be into the motor anyway for a 20000 model, to check valve clearances... another 5 or 10 minutes after you have checked your clearances, and you could be YZ timed and having a blast afterwards...

5TA -12180 this cam will work in the 03/450 and 98 to 02 400/426
The 5UL-12180 is the cam you need they changed the head in 04.

so the info is wrong? Indeed I need a 2004 model. Please doublecheck, because I just ordered the (wrong?) part? If some one responds quickly I still have time to stop the int´l shipment. Thanks!

I had to get the 5TA-12180 for mine.
I just checked there site and the Exhaust cam for the 04 states a different #
however the cam for the WR and YZF are the same # so you need to cancel
that order and adjust your exhaust cam to the YZF timing witch if I remember
right, you advance it one tooth on the chain from stock.
There's a lot of threads on this in here.
I guess the cam they gave me was for a 05.
This is the general rules for changing your timing to a YZ

kick it through with the auto-decompression cam and ti works SWEET
no more 3 kicks for 1 turn over.
The part numbers are different, you might want to try advancing the
cam like they did on the 400/426's however maybe someone else
has try-ed this and could tell ya if it works.
My mistake they are different numbers for the YZ450F and WR450F
so I would assume that they have different lifts.
