Working on a new Kayo Fox 70cc quad. Has no low end power. Needs a push to get started going. Once its going tho its fine. I removed the throttle limit screw. Anything I can do to boost low end power on this model?

 

May be a partly blocked idle jet. Remove carb float bowl and blow out jets with an air line.

 

I am having same issue on.my boys brand new kayo.fox 70 have to push to get him started lemme know if you figure anything out would be greatly appreciated dealer told.me ethanol in gas might be issue not sure bout that though.

 

Going to try to re gear or put a bigger back sprocket That’s the only thing I can figure as of reading other commments or maybe replace cdi

 

Put a 41 rear sprocket got more low end power going to add a front 12t and see if I can get anymore

 

Where did you purchase the front and rear sprockets I can’t seem to find them anywhere online. Thanks

 

Anyone have an answer to this? I need something bad, I have to constantly get off to push my boys up small hills.

 

read up on how to adjust the clutch on these... Sounds like the clutch is slipping under load

 

We have two of them, both brand new. I wouldn't imagine both are having clutch issues out the gate.

 

Those little machines are not much heavier than the motorcycles the engine was designed for. The motorcycles are capable of transporting an adult at up to 50mph so there is something sadly wrong if it can't pull a child up a small hill. As all these posts are about Kayo Fox 70s, my guess would be that yes there is a fault on them all, could be whoever is supposed to set the clutch at the factory doesn't know how, could be wrong ratios for gears chosen. A slipping clutch feels totally different to a badly adjusted carb, or too high a gear ratio but, unless you work out which it is, you are never going to fix it.
