is the cam mod really worth it?? im going to get the procircuit t-4, make some extra holes in the airbox disconnect the grey wire, and rejet to get the roll on power that a yz has, but will the cam mod incrase the power everywhere or only the top end?? thanks :)

You have to buy a YZ exhaust cam for the 450 due to the autodecompression system on the cam. It's not a free mod like on the 400-426.

Yes the YZ450 cam is worth it from midrange up to top the bike revs and accelerates harder. :)
