Hi, Dave.

No pictures just yet as the project is in an early (very early) stage of evolution. I’ve been steadily acquiring parts such as 750 conversion, upgraded oil pump, new E3134 cams, refurbished R followers, new 30mm concentric carbs, plus all the gubbins for a full engine rebuild including cam bushes; I’ll have see if I can borrow a reaming tool from somewhere.

I’ve also ported the head and had it straightened (skimming these old heads is a real no, no). I’ve also purchased Bob Newby Drive and various bits from Andy Molnar such as mudguards and a seat.

I have however fully rebuilt the short road holder front end with new parts throughout.

I’ll post some photos after I’ve modified the frame to mount the Manx style seat.

Sesman:
C’est fini…By far the most difficult restoration task I’ve ever completed.

McCabe-Thiele (Ted):
That looks as good as new Phillip, respect. 8) 8) 8)

Sesman:
Cheers, Ted. I will absolutely not consider doing another in that level of detail. It took about 6 hours and cost £50 in parts. Its the worst 6 hours of restoration time experience, but the best £50 I’ve spent.

Next time I’ll get the pros in and go for a long walk at the coast.

Sounds like an interesting build Phil. I replaced the oil pump in mine with a high flow Morgo pump. I had no choice but to have the head very lightly skimmed after the welding repairs to the combustion chamber. Whilst it was in the engineering shop the guy called me to advise the head needed spot machining on the pillars of the head fixing bolts because they weren't flat which meant the shoulder of the fixings bolts weren't sitting square to the face and that was what he thought was causing the head gasket to keep blowing. He said he'd seen the same thing many times before due to countless previous owners not using a torque wrench. Not many people could afford a torque wrench in the 60’s and 70’s and tight enough was good enough!
