I know this has been talked about many of times, but I haven't really found the answer I'm looking for. I have a stock 2008 yz450f with a full fmf system. The bike produces tons of power and handles very well. I'm very happy with it. I have recently heard that swapping the cams out for stock 06 cams will increase the power. Is this true? or does it just change the power output? As far as I can tell my 08 with the full fmf puts out more power than an stock 06 Another question I have is... will swapping the cdi or coils with the 06 do anything? Any input is greatly appreciated.
