Did nobody tell them the gudgeon pin wont fit the small end bush? Or is that just a careless lack of quality cotrol in the revised production? Yes, I could get the small end bus enlarged, but its not easy without detatching the rod, that's why, even if it is improved in other ways, I count it as &qu...

S/H piston from Pete Collings now fitted, Hamlins agreed that the "slight scores" were nothing to worry about and that its a 6 thou clearance in the +30 rebore originallydone for the JP piston. They very kindly checked and gapped the set of Welworthy Matchless std. size piston rings and ag...

Wow! Suddenly I'm cheerful again.
I have emailed them and will take the cylinder to Hamlins in Bridgwater tomorrow and see what rebore size is needed.
Thanks !!!

To suit my iron 1952 VH500. Bore is +20 at present and a +30 rebore might be enough but would be happy with a +40. Would be happy with anything that will fit as Single Spares have no stock and apparently will not "until middle of next year" And Drags also have none. So any usable s/h pisto...
