Hi All,
thanks for the advice and answers.
The fill the crankcase with parrafin checked the seals,
there ok thank goodness,
I got the barrels off this morning and the rings where stuck and a bit worn.
The main trouble was the square section rubber rings at the bottom of the barrels had not seated properly one was cut and the other side damaged on the other. (suspect they were old stock and had swollen)
so its new piston rings (+0.060″ if i can find them ) and ‘0’ ring seals from Ireland.
I’ve not run the bike too much so no damage done.
Thanks again
