Differences in throttles

Recommended Posts

Just a curious question in regards to the difference between four stroke throttles and two throttles. Why does the four stroke have two cable’s operating the carb when the two strokes only have one? Is it a safety feature of some sort…?

I don't know if it's considered a safety feature or not, but the twin cables are "Push /Pull". It does not depend on spring pressure to return the slide to closed, and the smaller 4 strokes don't have it (our 100, sportrax 90 and 70 don't). :cry:

Ever had a stuck throttle? If so, you'd be wishing you had a second cable to close the throttle instead of just a spring. I believe one reason why they're on 4 strokes is that a 4 stroke has more back pressure thru the carb, and a slide, under spring pressure only, is susceptible to this, as it's return to the closed position between back pressure pulses would be less than ideal. Hence, the second cable to pull it closed.
