Hello there, I've had my 450R for a couple of months and I am interested in boosting it up. It's a clean slate cept for a UNI filter. I heard about this White Bros timing change. I was wondering if anybody knew what it was about.

Alright, I got it in today. It's called a White Brothers cam sprocket, product #-WB#1654-. It adjusts the sprocket +5 degrees. It mounts onto the end of the cam shaft. It's "designed to increase low-end power from 1600-7000 rpm with out sacrificing top end power. This is achieved from the effects of advanced intake valve timing."
It's designed for the CRF450 motor. My question is has anybody made this modification? Any info you guys can giv :mellow: e me will be helpful. I am a newbie.

Did you ride with it yet? Please report back thanks.
Is this a stupid question, but could use rev limiter box if you mess with the timing gear, would it throw the timing all off etc
