just had my 96 mxz 583 rebuilt, and i've got a few questions. first, how long should i be takin it easy on the fresh motor?the dealer told me for 300 miles and the mechanic who rebuilt it told me for about an hour. which one is closer? second, my clutch doesnt engage until about 5000 rpm. is that normal, or does it need to be lower? third, my gas mileage sucks big-time. i figure im getting around 4 mpg. that cant be right, right? and lastly, im running Doo mineral oil in her. is this a good, safe oil and will it gum up my R.A.V.E.s? is R.A.V.E. cleaning something i can do at home, or should it be left to professionals? any help would be appreciated.
