Does anyone know the differance between the ofna hyper 21 8 port and the ofna hyper 21 8 port race engine? are the mouning holes the same?
 
i have the race.. fits perfect.. you will need to buy the one off the guy on ebay that has the pull start, the differance is .2hp, silver head thats bigger, black engine block, the crank has a bigger inner brng, besides that everything else is the same.. break in might be a PIA.. but after a gal of fuel thru it it starts in 1/2 to 1 pull.
