 As soon as they were mounted, the result seemed good: the precision and sensitivity of the throttle was significantly improved compared to the old cracked membranes. In a few months I will check the actual seal of the membrane and especially of the glue. The one supplied reports among its characteristics a maximum operating temperature of 80 °C. Probably the Loctite 454 has better characteristics. As soon as they were mounted, the result seemed good: the precision and sensitivity of the throttle was significantly improved compared to the old cracked membranes.

 Remove tha tank and connect two vacuum gauges to the cylinders intakes using two joints plugs (Honda part 16214-MB0-000). Provide the fuel in some way, warm up the engine and adjust the idle speed (1100 +/- 100 rpm). The difference in vacuum reading should be 40 mm Hg or less. Remove tha tank and connect two vacuum gauges to the cylinders intakes using two joints plugs (Honda part 16214-MB0-000).
