Is it worth it to change out the stock waterbox? if so which waterbox will make anymore power on a piped,carbed,milled and lightnened flywheeled 650sx without getting toomuch louder?

Just drill out the stocker. The after market ones are retardedly loud and offer little if any performance gain.

 

[anthonystempak]

what is the procedure for drilling it?
