WR400 cam question.

1 post in this topic

I have a 1999 WR400 with some modifications, and I would like it to "breathe" a little bit better, has anybody tryed a YZF426 intake cam YZF450 exhaust cam combination? The yzf426 head is identical to the 400, so I know the cam will fit, I'm just wondering how much power it would add.
