prelit Posted September 12, 2017 Report Share Posted September 12, 2017 Hi guys, Can anyone help me with a starting point for the idea compression ratio for a d14 Bantam with a b175 centre plug head. Thanks, Prelit Quote Link to comment Share on other sites More sharing options...
hencam Posted September 12, 2017 Report Share Posted September 12, 2017 try contacting Rex Caunt. he is very helpful and knowledgeable, just follow his instructions for calling time on his website, after 18:00 i think? i had a nasty experience with mine, somebody skimmed the head, knocked the big end out after about 12 trials, found a standard head and it had a 2.5mm upstand/gasket face. mine had been skimmed almost flat with the bottom fin.
