I am about to order new pistons from Ural-Zentrale.
When i measure the cylinders they are about 78,12 and 78,24.
I guess it would be enough bore up for the 78,48 pistons.
Perhaps it would be good to put in the "Piston ring sv engines Schoettle 79 mm"
that they have in most sizes but not in 78,5. So i guess it will be the 78,9 pistons.
Does anyone have an opinion about those rings compared to the original ones?
And what clearance should i tell them to make when i leave it away for boring?
