Hi there, I have a 1977 Mk 1 with 74,000 miles on it. I had the heads done up about 8 months ago with new exhaust valves and guides replaced. motor is running good but has started to blow quite a bit of oil out the engine breather hose. I checked cylinder pressures 8 months ago and they were 170 left and 160 right, they are now 165 left and 150 right, I have done about 5000miles hard riding between checks. I will check engine breather box valve operation to try and stop oil loss out breather but wonder if I should also check rings etc? Dose anyone know what cylinder pressure i should have?? Cheers Croc. ps. couple of pics of my bikes for interest.
