Hey guys! I am in need of some serious help with my little quad. Take a listen to the video and see if you can decipher why it is running like it is. I have yet to figure it out.

I have cleaned and rebuilt the carb with OEM parts and jets. Put in a new petcock, fuel filter, and fuel line. Replaced the computer. Put on a new coil, wire, and cap. Replaced the spark plug. Checked the compression and valves. Everything was in spec with the manual. I am at a serious loss. Please let me know your thoughts. :mad:

Ah yes, I could see that for sure. Nah it starts with just a tiny tap of the starter button. Its always been that way. Plus, this one doesnt have a pull starter.

In the 2nd video I just posted you can hear it idling like a champ right off the bat. When I give it gas is when I encounter the problems. Check it out and let me know what you think.

The only way the fuel is getting pumped is by mother nature, gravity. There isnt a fuel pump.

But I agree, I think its a fuel issue...perhaps jetting. Not sure cause it ran fine at this elevation prior and it has stock jets in it. So one would think that is a fine base point to start from with minor adjustments thereafter.

Yeah there is. New Yamaha style petcock and got rid of the vacuum port on the petcock and blocked off the port on the carburetor. Also on the cap I have a good vent hose coming off of it.

I took the line off the carb and let the fuel run through the petcock, filter, and line and it ran freely. No blockages.

      having an issue with the unit when running under a load up a hill or in high gear, seems like the belt is slipping, there is a clapping sound coming from the primary clutch like it releases and snaps back in. i don't think I should have a noise like that. this is a friends unit and he has already replaced the primary twice with the same result.
      not sure where to look next

      I Ran across this video today comparing an aftermarket to OEM Carb on Suzuki Vinson, thought it might generate some interest, it is quite long but informative.

      My king quad 700 runs rough when cold then won't start some times but not often when it's hot. And occasionally smoke's a lot when it's cold I'm guessing that's rings but I'm worried unless it's causing the other problems
       
       
       
      All help is appreciated thanks

      Has anyone else had an issue on older king quads where the oil would leak from the top of the head (due to a failed gasket) and drip onto the hot exhaust? Mine got so hot one time it caught fire. Just wondering if this is a common issue, as I've seen the same thing happen on multiple bikes that were the same model.

      My 2014 750 king quad stalls sometimes when I touch or turn the handlebars,the problem has gotten worse,my machine has 475 miles and is only trail ridden,I have a new factory battery and i have 14.2 volts when the quad is running and 13.3 on the battery when not running,also using a multimeter there is no change in volts when turning the bars until it does stall,If I pull the 40 amp power steering fuse it will not stall.......I've been told its the ECU,Hate to buy one if thats not the problem,but its kinda leaning towards that,,,,,need some opinions.
