I am replacing the valve cover gasket and cleaning the carbs on a 1981 seca 750. I figured while the valve cover was off I would check the valve clearence. Does anybody know what the clearence should be set at and how to check? Was also wondering what the torque specs are for the cover bolts. Also I have the gauges for syncronizing the carbs but donĀ“t know what they should be set at. Any help would be greatly appreciated.
