Who has used the yz cam? Is it worth the cash. If their are any advantages to the yz cam I am willing to buy it. Input anyone? Cam mod worked well but a little to much compression for the starter on my bike, atleast. I would like to think that the decomp feature would work better on a cam designed for that timming. I don't understand why GYT-R has not marketed the yz cam for the yfz if it works perfectly. I'll figure it out. Thanks anyone.
