03 450 cam in an 08 450?

6 posts in this topic

I heard that 03-06 exhaust cam in an 07-09 450 will help with bottom and mid? I spun my camgear and have been looking for a replacement, I found a real good deal on an 03 cam set.

The '03-'05 cam is different than an '06, and the '06 is preferable for this application, but both will work.  You will loose less top end with the '06 by a small amount.


The two other factors not to be overlooked on the '08 are the stock exhaust , which is a remarkably bad piece of junk, and completely out of character for stock YZF pipes, and the CDI box, which has a weak timing map.  The best choices to replace the CDI are (in order of preference) from the '06, '09, or '04 models.  Avoid the '05.

Thanks man, picked a set up for $35 off eBay

Get a chance to install it?  How'd you like it?  I have an 07 YZ exhaust cam in my 07 WR, but it's missing some power on the low-end.  Wondering about the 06 and 03-05 yz cams...
