October 21, 201213 yr Hi everyone, Im on rebuilding my 1972 mar and im needing advice on oil types and amounts. I've replaced the fork seals and I need to know what type of fork oil to use and how much to put in each leg? Also Id like to change the gear oil does anyone know what oil to use and how much to put in? Thanks Graham.
October 23, 201213 yr I had replied to this, no idea what happened to it. 180cc in each leg, 10W works fine although oil grade is personal preference. Gearbox/clutch share the same oil - 800cc - 1000cc of light gear oil such as Silkolene Light etc. The clutch case has a small screw bottom left which is a level check plug. I think 1000cc might be the spec but I've always used 800cc with no problem. If ever you change your clutch plates, Barnett clutch plates from the US work very well, they don't stick, slip or drag, have more bite than standard spec plates, therefore you can back the tensioning springs off a little more and get a lighter pull on the clutch.
