ORIGINAL: Gringo Flyer

Very easy. You just take the cover off the top (dont know the official name of it) of the rockers and adjust the clearance with a spark plug gap measurer (not sure what that is called either). You are supposed to check the clearance before breaking it in and then every 10 or so hours of flight. Its pretty easy.
That would be the valve cover and a feeler gauge...Rog
