I mentioned earlier that the big-end con rod was too long as drawn. I was wrong as the underside of the crosshead needs to clear the crank at bottom dead centre.   I have noticed some errors on my build probably due to poor measuring >:(  The engine has been dismantled, boxed and put away for a while as I continue camping and sort out my two mortobike rebuilds.  As a result this thread is "on hold" for a while but will hopefully continue with renewed enthusiasm in the autumn.    Cheers for now    Terry

Sorry to hear that Terry  :( I hope you wrote down your findings so that you don't have to re-find them when you pick it up again.

You have not told us anything about your new bikes, it would be nice to find out a bit more about them  :). In my younger days  :old: I restored a few motorcycles of my own before someone (MEM member Old Bill) introduced me to model engineering  :embarassed:.

Cheers Jo,     Nothing exotic I'm afraid,  just a couple of 1963 Royal Enfield 250cc. Dismantled by their owner 45 yrs ago and dry strored ever since. A last (failed) attempt by Britain to fend off the imports.
I have owned nearly 30 bikes in my time but never an Enfield so will be a change.            Terry

As a Biker for Life (and never owned a car), I'm curious too - any pictures ?

45 years in dry storage h - that is a long time, so even better if they are oiled (so to speak)  ;)

Enjoy the time with this project too  :cheers:

No pictures as yet Per.   No, the bits have not been oiled :( so a bit of work ahead.      Thanks for your interest.          Terry
