I recently removed the speed limiters on the kfx-80 and now can't get the thing to run right. I removed the exhaust restrictor and the throttle cable limiter. The problem is it will run fine until it is trying to go up a hill and then the thing will bog down and giving it more gas seems to make it go slower and will then die on me. Sounds like maybe a carb problem. Any ideas? I replaced the spark plug and stil the same problems! Sucks having issues with a "brand name" quad. Hopefully an easy fix!

Thanks for your help!

 

Did you get the carb slide in correctly? Put the slide together correctly?
I've seen both happen. [img]i/expressions/face-icon-small-smile.gif[/img]

 

I have the same problem on my bike and its a kfx80 to me and my dad thinks its the floats in the carb but i do not have the manual so its hard trying to get the float set to the right height

 

Welcome to the forums.
Maybe if you start a thread on what is wrong and what you've done to test/fix it.
