Oddjob:
I used to use BP VF7 back in the day, loved that oil. It had so much cleaning detergent in it that working inside the engine was a treat, completely clean inside, no staining of the alloy inside at all, whereas engine run on Duckhams were black inside, never a big fan of Duckhams, preferred Castrol GTX if I couldn't get VF7.
Seem to recall VF7 was either 5/30 or 10/30.

When working in the 70's we used silkolene, which we got from Popes in Bristol who were a pushbike shop but also the main Suzuki spares dealer for the sothwest and used to buy an artic load of oil at a time in 5 gall drums

Back in the 1970's Silkolene oil based in Belper was good value for money - all made from waste oil collected from mostly local garages - early re-cycling in action.

Exhaust are hm341, carbs are 657b, needle set in middle, compression all around 160psi has just had top end rebuild new rings valves re ground, dynas ignition so no points
