2005 Suzuki Quadsport 50 Regulate Throttle

[hornythrony]

Does anyone know ways to regulate the speed etc other then the throttle screw? I have turn it almost all the way and it won't move on hills but keeps getting faster on flat gravel roads. I have a Chinese quad that's bigger but is a 3 gear so I just put it in first and let my kids go nuts cuz it might rattle it self to S... but it only goes so fast

The thumb throttle adjustment is the only "legit" way to limit speed.  Yes, it does get faster on flat ground, up to the speed corresponding to thumb position and it may even go beyond that down hill.  I would think even if there were an adjustable rev limiter in the CDI it would still behave the same uphill and flat ground.  The only way that i see to not have it slow uphill and fast downhill would be a speedometer limited throttle like a modern vehicle so that it will only do say 15mph uphill and 15mph downhill/flat ground.
