I fired up my brand new mexican 1600 motor.  I had the valves set pretty loose at first.  I ran it about 20 minutes last night.  Today I drained the oil and am about to adjust the valves.  With the motor still new and not broken in,  should the valves still be adjusted kinda loose, like 008 or even 010, or should I go straight to 006 ?  Any other advice for breaking it in ?  Thanks,
