BrianEb Posted July 7, 2005 Report Posted July 7, 2005 Just wondering if anybody know what the proper range is for a compression reading. Clymer says yamaha does not list compression readings Quote
watkins Posted July 7, 2005 Report Posted July 7, 2005 Stock should be 135PSI... but mainly you want to see that each cylinder is within 10PSI of eachother. Quote
