I'm interested in the size of the cable wheel on the carbs. My '09 EX500 uses the exact same part number throttle (
46019-1077) as many years of the PreGen EX250, and it's 1/4 turn to WOT.
The (identical) throttle is obviously pulling the cable the exact same amount, so it must need to pull a lot more cable around the carb wheel to achieve the same movement.
