Bryanj:
I put a Morgo 750 kit on my old preunit, started burning white smoke at about 6 months and was told it was actually burning oil in small quantities, std morgo rings turned out to be BSA A65 +20 i think from Charlies in Bristol.
I was a lot younger then and could replace mains in 3 hours start to finish

Sesman:
Yes, Dave.

Both the rocker box pillars needed machining. I’ve gone for the rotary pump and will be adding additional engine breathing. Bryanj mentioned early failure of his Morgo conversion. I can’t vouch for the product of yesteryear, but I checked out Morgo and Routt variants in person and to be honest there was very little to choose between them. In the end I bought British.

Next big decision is whether to purchase updated rods. Mine are straight without any external evidence of stress and have been peened and polished, but I’m just not sure. I’m going for an efficient tune, not a high revving, high compression arrangement. At £250 per rod it’s a big investment. I just can’t conclude if it’s a necessary one…

Bryanj:
Wasnt really a failure, still ran fine and strangely did not use much oil just gave out white smoke in small quantities, never did fit the rings before i sold it and it could have been me not running in correctlt

Laverda Dave:
Morgo are very specific about running-in procedure and using the correct oil during running-in. They actually sell a specific oil for the task.
I went up to Morgo after speaking with Miles on the phone as I bought a set of barrels and pistons to replace the worn out (after 250 miles!) ones fitted by the original engine builder who built the motor. The new barrel and pistons didn't fit. Miles told me to take the new ones back and he's investigate. Turned out the original Morgo barrel had been cut down and the forged pistons replaced by Hepolites. He machined the barrel to take the top fin off after measuring the height of the old Morgo barrel.
Got to say Miles is a great guy, very helpful, full of biking stories and he insisted on giving me a lift back to Leeds station with the newly machined barrel as well as the old one. I've never drunk so much tea either!

Bryanj:
When i got mine back in the 70's i collected the kit and they had several Rickman Interceptors there
