hi, we've been trying to figure out this prob on a '05 kfx 700, it skips on one cylinder at certain times and if u let it idle for very long one cylinder will die its like its not getting spark. we adjusted the valves, cleaned the carbs,theres no vacuum leaks and the gas is new. has anyone ever heard of this problem before? any help would be awsome!

 

Another member on this forum ( zmann ) has been working on a missing problem with his KFX700 as well. However his motor has quite a few mods from what I understand.

 

Hmmm,,,just a thought--a bad coil..or a bad cdi box

 

Yeah that could probably be a solution replace the cheapest first is always my moto or take it to a pro well i will give my mechanic a call and i will let you know what he says.
