Hi, I have a 74" UL with re-sleeved cylinders stock bore, with brand new NOS HD pistons. The rings have a one piece solid oil control ring with no windows. My machinist wants me to go to a Hastings three piece ring with the corrugated center oil ring for better oil scraping and an easier time for the oil to find it's way in to the windows in the piston. Is there any reason not to follow his advice and keep the cast oil ring, or is an updated modern Hasting style oil ring a better choice? Thanks.
