Stihl 460 big bore upgrade

[shortlogger]

Has anyone used the Stihl 460 bigbore upgade for any amount of time ? I am curiouse if they are worth the money, And how well the crank can handle the extra HP ? I dont want to ruin a perfectly good saw over a few extra cc.

I got one on my bench right now going back to OEM, the cutter put this big bore on and was never happy with the power it put out plus the piston broke only after a very short time , if you are a person that runs the saw alot and count on it running go with OEM
