August 12, 201115 yr hi when fitting pistin rings to my 199A do they face upwards with the groov in them? allso the thiner off the to goses on the bottom is this right? daft question but im just making sure i know about the arrow on the piston it faces foward. and the rings close on the notices. one other thing is the bike had loads of compretion and ran sweet so will it be ok to put the old rings and top end bearing all back together witch all look good?
August 12, 201115 yr Different pistons have different design rings. It's very hard to tell what you have there from your description but maybe one ring is shaped like an "L" in cross section? and the other is not? If the rings are different then the grooves in the piston should be different too - more info needed here
