Reply To: does my bike need to throttle body sync?
The throttle bodies have air lines coming from the ISCV unit , it is possible to measure how much air is being drawn on full throttle / half-throttle , or switch of the bike with throttle closed , it is possible to measure if the throttle butterflies are fully shut.
Also if you take off throttle bodies off and take sensors off , then pour a little bit of oil down there, and see if the butterfly leaks out on the other side ? = this isn’t fool proof, so it is just an idea! = I did this on a row of carbs for Kawasaki ZZR , because i had to be sure all butterflies were equally opening and closing so each cylinder gets the same air flow.
