Ya you can change the timing to retard it and make it like the YZ450F dirt bike motor. Make the YFZ450 run alot better more topend and they say you lose bottom but I couldnt feel the lost.

Search on here or any of the dedicated yfz sites for "cam mod" and you can find everything you need to do it, heck there are even video's around.
