Synching K Bike Throttle Bodies (applies to all K bikes)

[tsbt]

I found that before a long trip I'd synched the throttle bodies with the carb-tune and it was running smooth, upon my return 4 days later I had to synch them all over again. Is this something I should do regularly, or am I dealing with another issue causing the bodies to go out of sync? Perhaps it's time for my fuel injectors to be cleaned, not sure. Either way it has me scratching my head.

Well you can in fact you positively do on the oil head twins. But, their tb's are controlled by a separate cable to each one and you adjust the cable pull to synch again at about 3-4k revs. Setting on the K would be harder and more "mechanical"

Thanks Duc750, the only other thing I can think of is that the throttle adjustment screw rubber-washers are worn causing them to loosen and twist themselves out as I ride, obviously messing with my perfectly tuned bodies.
