I found a good deal on a set of hotcams for 10-13 yz450's. I know the engine was changed in 10 but was wondering if the newer cams bolt into previous year heads?

I believe the new fuel injected bike has the same part number cams as the 07-11 WR450.

Does that go for yz's or just wr's? I could see the new WR motors using the same cams but in 10 the yz engine was changed alot.

The YZ cams from 10' up will not fit.
By the way I have a used set of Hot cams with a cheap price if anyone is interested.

The FI 450s have 4 valves.  The WR450Fs and earlier YZ450s have 5 valves.
