reference number to the parts list.  When installing the cylinder hold 
down screws always use a good grade of RED thread locker.  For all 
other screws use BLUE thread locker. 
 
Re-lubricating the rocker arms should be done after every 10 hours 
of run time.  The rocker arms should be lubed with a high grade, 
thick Molly lube.   

 

 
 
 
 
 

Be cautious not to over lubing the rocker arms. 
Too much lube will fill the pushrod tubes and hurt performance.  A 
good idea is to keep a log of run time on your engine.  This will help 
you know when to lube the rockers, adjust the rockers, inspect the 
engine, etc.  For your convenience, we have enclosed a log book 
with your engine. 

 
       Also check for loose components by observing if any black residue is 

omitting from between parts and components of the engine.  This 
black residue is finely ground metal mixed with oil that seeps from 

between engine parts when the parts are loose or not sufficiently 
tight.  DO NOT run the engine until this situation is properly 
addressed. 

 
Valve Rocker adjustment

 is a critical part of your engine’s 

performance.  To ignore adjusting the rockers will lead to excessive 
wear of the valve train and considerable loss of performance.  
Adjusting the intake and exhaust rockers of each cylinder is 
relatively easy to do but requires attention to finesse.  If the rockers 
are too loose the engine will loose performance and be hard to 
start.  If the rockers are too tight, it will cause excessive wear and 
engine failure.  The rockers need to be adjusted after the break in 
period is completed and then every 10 hours there after.
