Hey all, I've been working on getting up enough posts to download the service manual, but in the mean time, maybe someone is interested if giving me a few deets in a reply? If not, no worries.
I'm look to confirm a couple things that I've picked up from Google searches.
First, I've heard that the factory mixture setting on the carb for this bike is 2 full turns out. Can people confirm? I've also heard that it's a fuel mix valve, not air, so screw in to lean, out to richen? Is that correct?
And for the valve clearances, I've heard two different specs, one is intake 0.004" and exhaust 0.006", and that other I heard from a youtuber who claimed this bike had 'very tight' valve clearances, said 0.002" intake, and 0.004" exhaust.
If anyone wants to comment on the above, I would be appreciative, if not though I'll keep posting until I can download that service manual

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).

Hello everyone! Just joined up. As an introduction, I've had a Kawaski Bayou KLF300 2x4 since my Dad bought it new in '86 (nearly as old as I am), done a lot to keep it running through the years, especially with starter motor and carburetor work.
I'm also working on a 1993 Suzuki QuadRunner 300 for a friend. Seems original carb was MIA so he bought one online, put a 120 main jet in and then asked if I could help - still running bad. So I'm here asking if anyone has the specs for idle screw turns, float height and valve adjustment specs. Looking to download the service manual soon from here when I'm able to. I've cleaned out the carb and reassembled it, it had some assembly errors, and so far got it to start and idle fairly well, bit unstable, and it drives good but tends to stumble when starting out with light throttle, and then when releasing the throttle sometimes it dies. Think I'm getting close to having it dialed in. Also have to look at the rear brakes, pedal goes through the floor and no braking at all. Everything else appears pretty good, even the speedometer works.
Thanks in advance to everyone, cheers!~

I own a few older quads mix of kinds a couple of Yamahas, a Honda, can-am a Kawasaki, they are older quads but in good shape the question of the day is....... what's the best way to polish up the plastic?
I have found that Dollar General mold remover is good to get the black stuff off the plastic works good, but was wondering how you polish up the plastics on yours.
