I am going to buy my buddies 95 zert 800. What can I expect form this machine as far as top end. I have some apexes (stock) and 800 P-TEK revs to compete with along with an SRX 700. I assume it is clutched and ready to go as the guy tunes his stuff very well and maintains it. Also can I out an ETT under it next year as I want to put a D&D 1004 kit in it.
