I just CCed one of my heads. I got 62cc in both chambers. I thought that stock was 60cc? Does this mean that the buret that I bought is a POS?
By my math, 62cc chambers would give me 9.2:1 with a .040 deck height on a 96x78 mm 2258cc engine... 60cc would give me 9.4:1. Heads need a rebuild... I'm just trying to figure out where I'm at for a starting point. |

Its quite possible that you have a broken calculator.
with your numbers. 62cc head, 0.04 deck, 96 bore, 78 stroke is 9.1:1 60 cc head, 0.04 deck, 96 bore, 78 stroke is 9.4:1 http://www.aircooled.net/gnrlsite/resource...ninfo/calcs.htm Rich |

I'm still curious about my apparent 62cc chambers, though. |
