South Florida.
How much it worth?
Pros: looking decent.
Cons
No brakes.
Front wheel bearings are shot.
Idles, but sometimes will shot off. Most likely when cold.
Gas smell and little bit steam in the air filter box when I started it.
Display screen won't work.
Tires are dry with cracks.
Not sure if has title, I will check and update.
How much do you think it worth?

So, I found myself in the only 5' deep water hole in Moab with the King Quad. Before I could get off it swallowed water at idle and died. The river water was not very clean. I pulled the plug and pumped the water out of it with the starter. I cranked on it and it popped for a second and then was done. Towed it back to the trailer. When I got home I checked the compression and it had none. I have a factory service manual. Disassembled and found the rings stuck in the piston lands. New rings and back together. I try to start it and get a C12 code CKP - crank position sensor. Troubleshoot and find it to be shorted. Installed aftermarket CKP, still get code. Check voltage on new CKP and only get 4.5V, manual calls for 5V minimum. Pulled every connector apart on vehicle and cleaned. Have continuity from CKP sensor side of connector to ECM harness. Install a known good ECM from another 2005 KQ I have. Vehicle fires and I let it run for 10 minutes. Shut it down and put the original ECM in and get a C12 code again and won't fire. Put the known good ECM back in and get C12 and no fire. Tested both ECM's in the other KQ and runs well on both ECM's. Installed a used stator and CKP. Still get a C12 code. Check used stator, 200 ohms and 6.5 V out of the CKP at the ECM harness. Checked ground at ECM harness and it is good. Checked spark with spark plug and without, none. Checked resistance and peak voltage on coil and it is in spec.
This thing has me baffled. All of the electrical possibilities seem to check out. Might be far fetched, but could the rotor key have sheared when it shut down suddenly when the cylinder filled with water? I know rotary lawn mowers can shear the flywheel key when the blade stops suddenly from a rock or stump. If the key is sheared and the flywheel is out of time by a few degrees could this be giving the C12 code? The voltage output is correct but at the wrong crankshaft position (wrong time).

hey all looking for some guidance on my KQ just replaced stator, and regulator on the quad and after putting all the plastics back together and finishing the snorkel kit she has no spark when i check voltage on the power wire going into ignition coil im getting about 12v and if i crank it im not getting my "peak voltage" (80v) any help would be greatly appreciated
thanks , Nick

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.
