RSMachine 84.5mm B20 piston rings part number?
Does anybody know the NPR piston ring part number for B20 rsmachine 84.5mm pistons? Bought a set of those pistons and it didn't come with rings. Seller doesn't know and RSmachine didn't get back to me after calling them and emailing them last week.
What makes it hard is that listed part number on NPR catalog is SWH30437ZZ(-2) which describes the thickness of; Top ring:1.2mm Second ring:1.2mm Oil ring: 2.8mm Bore: 84.5mm
That will not fit the rsmachine pistons as it requires the top ring thickness of 1.0mm. I must say I am beginning to regret buying these pistons because of the service, should of went with YCP's.
