Re: Rally spec L20B

Terry, I can't recall any numbers on the head, I am back at work now and probably won't have a chance to look at it until the weekend. The motor is at a mates house. I do know that the head is about 3.8mm from minimum shaved height, based on what my mechanic mate said.   cheers Rob P ----- Original Message ----- From: Terry Rudd To: [EMAIL PROTECTED] Sent: Tuesday, September 10, 2002 6:30 PM Subject: RE: Rally spec L20B. twin 45DCOE Weber settings Rob,   To calculate CR you need bore, stroke and head volume - what head does it have on it? Most L20B have 41cc combustion chambers less a tad for any shaving etc example of L20B head is U67.   regards Terry -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Rob P Sent: Tuesday, 10 September 2002 7:24 PM To: [EMAIL PROTECTED] Subject: Re: Rally spec L20B. twin 45DCOE Weber settings Any way of working out the compression ratio without pulling off the head? The sump is off at the moment so I can measure piston throw. It's the volume of the chamber at TDC that is gonna be hard to calculate.   --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/membersozdat@datascribe.com.au/ ---------------------------------------------------------------------
