Hisun HS700 - Piston rings in Hisun UTV SxS Forum Posted August 21, 2022 Cliffyk, did you do an upper end repair on your HS400 due to smoke? I have an intermittent smoking problem with mine. Sometimes it’s good and other times it’s terrible. I suspect the oil ring is sticking as compression appears good wet & dry.
