I have an 18 zr 8000. Bought sled with 900 miles it had suffered snow ingestion and i noticed scoring on pistons. Pulled top end and had cylinders gone through with new pistons/rings etc.
Reed petals were fine, cages on other hand were delaminating and had chunks missing from the rubber moulding. I replaced with vforce since they were proven to make power on the 18+ engines.
Was not happy with reed cages at all how damaged they were
