How related were the Seven, Big Seven and Eight Engines? |

Hello
Have read conflicting things regarding the exact relationship between the 747cc Seven, 900cc Big Seven and 900cc Eight engines.
Some say the latter two are virtually clean sheet designs with little commonality between them or to the Seven engine, others say either the Big Seven or the Big Seven and Eight are both redesigns of the original Seven engine.
Also if the Eight engine does indeed share a relation stretching back to the Big Seven or Seven engines, was 900cc the maximum capacity the engine was capable of or was further stretch available (as seem to recall articles about Seven-derived engines being stretched to as much as 950cc if not more)?
And lastly is it known whether the Big Seven or Eight engines were recipients of an OHV conversion along similar lines to the LAP Head for the original Seven engine (possibly by Alta, etc)?

Can anyone tell me how to remove the horn button/lndicator cover from the steering wheel, is it retained by clips and pulls off or is there some other retainer.

Crack free Conrods |

Hi, I am looking for 2 crack free conrods for a 2 bearing engine, ideally with good white metal and which can be resized to 1.280”.
I would be pleased to hear from anyone who can help.
I have spare Conrods, but hoping to find some that can be resized rather than going to the expense of re whitemetal.
Many Thanks Gene

Hello All
I wonder if someone called advise me please.
I have just stripped my kingpins on a Mk 11 Ruby axle and have discovered that
one has a hole all the way through the pin and the other one is sealed at the bottom.
Both have the threaded hole at the top but I was wondering which one is correct please.
Thank you for your time
Graham.
