Does anybody now how to do this, I have never done it. The manual says to do it for every service, and has no info how to do it.. Any info would be much appreciated . Thanks guys
Every cylinder pulls/creates vacuum regardless of fueling system. FI is just like carbs when it comes to synchronization. Hook up Carbtune or similar gauge and adjust until all are equal.But FI syncing is different from Carbs is it not? or do they rely on the same vacuum system?
I believe Yamaha says to do it at idle, but it would make more sense to do it at cruising rpm for most. Unless there's something I'm missing. I'm going to sync mine at idle first then if there's a huge difference between that and cruising rpm 4500-5500ish then I will sync around there and see if the idle is rough.So do you synch at idle or at like 5500 normal cruse-ish or at a different RPM all together???
