1988 Honda CR80 Torque Specs
Shop parts for a 1988 Honda CR80 Dirt Bike.
The 1988 Honda CR80 continued with the liquid-cooled, power-valve-equipped 80cc two-stroke formula that had become standard for competitive youth motocross. By ’88 the CR80 was a mature, well-sorted machine giving young racers everything they needed to be competitive in their class. Correct torque specifications across all fastener groups keep a ’88 CR80 reliable through a full season.
Engine Fasteners
The 1988 CR80’s power valve system continued to be a key differentiator in youth motocross. Both the main power valve and its actuating mechanism have small fasteners that need regular attention. The cover bolts in particular are prone to loosening from the vibration of a high-revving 80cc two-stroke.
