Unclefester Posted December 6, 2006 Share Posted December 6, 2006 Has that engine actually got a Big Valve head or is it just the BV camcover I wonder?  Can't recall what size the valves were on the BV.    Foolish behaviour on 3 wheels a speciality... 😬 😬here *eek* Edited by - Unclefester on 6 Dec 2006 22:48:11 Link to comment Share on other sites More sharing options...
Englishmaninwales Posted December 7, 2006 Share Posted December 7, 2006 BV inlet size 1.560-1.566in (39.776mm), standard 1.526-1.530 (38.760mm) Sad, I know...... Link to comment Share on other sites More sharing options...
MarcNS Posted December 7, 2006 Author Share Posted December 7, 2006 They look like 1.562 so does that make it a Big Valve? There have been some prestine TC engines going for £2.5k but this is not quite prestine, but has the power. someone has put a bid on it, who was it 🤔 Link to comment Share on other sites More sharing options...
Unclefester Posted December 7, 2006 Share Posted December 7, 2006 Yup! It's got a 1mm bigger inlet so it's a BV.  Does this make us geeks?  I do hope so.  Foolish behaviour on 3 wheels a speciality... 😬 😬here *eek* Link to comment Share on other sites More sharing options...
Nigel Riches Posted December 11, 2006 Share Posted December 11, 2006 Hi Marc, you can fit the X-flow block to the twin cam head, but it's a bit of a mission, if you Blat mail me your home e-mail I'll copy and send the screed with instructions, this is info I got back in the late '80's, hope it's of some help, Nigel. 1982. 5 speed, clamshells.

Silver 21 Posted December 11, 2006 Share Posted December 11, 2006 Marc I don't think this is expensive for a TC, to properly rebuild a Xflow you are going to have very little change from £1500-£2000 so at its current price it doesn't look too bad. Graham Lotus 7 Club General Secretary  Link to comment Share on other sites More sharing options...
