Anyone try to check their throttle body synchronization using two vacuum gauges? The manual says to do it at idle with the Yamaha vacuum gauges hooked up to the two ports on the throttle bodies and map sensor unhooked. The reading should be within 10 mmhg of each other. Problem is my gauges (not Yamaha brand) go all over the place at idle and don't stay steady enough for me to read them.
