I got my KLF300 running again with your help a couple of months ago, at that time it was the ignition coil that had failed. It has been in use since then without issues until two weeks ago.
When the new issue showed I was going at about 10km/h and it suddenly slowed to a halt. I started it again after that with choke and I drove it 400 meters and parked. Next time it was really hard to start, and since it was low on gas I thought that was the problem. It didn't get any better with a full tank, so I assumed it was the cold weather, and adjusted the pilot slightly.
After that it I actually got it started again with full choke and some slight gas, I drove about 300 meters and then it slowed down to a halt again. After that, it hasn't started again.
The compression is 165psi. The spark has good intensity, the ATV has functioned before with the same spark "intensity"/light. I *assume* that it has gas as well, there is definitely gas on the spark plug when I remove it
I have checked the carburetor slightly, the float works, diaphragm looks ok, but I haven't disassembled it to really look for dust and such in all the small places.
My theory right now is that it might've been some dust in the gas tank that went into the system, it's just a theory
I'm thankful for all the help and pointers I can get, don't hesitate

My Yamaha Big Bear shifts through all the gears good, goes into reverse smoothly, but when i go to get out of reverse it takes a lot of effort to get it back to first gear, and even then it does not go very smoothly, have to pull up on the pedal really hard, anyone else ever had this problem. Any ideas would be greatly appreciated.
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 I have a 1999 Honda 300 4w/drive and I just replaced the Oem carburetor with a aftermarket carburetor after installing the carb on the bike it started great and idled like new one but when I shifted into first gear and tried to move forward it died, I shifted back In neutral and the wheeler started easy again I let it set there to see if maybe it needed to warm up but when I shifted into first and tried accelerating it died again, I am not a use to working on it and would appreciate any advise thanks
Im finishing up on the Big Bear, just tying up some loose ends and its done.
My next project I actually bought first, but the Big Bear seemed like it was more challenging so tackled it first. Now looking the Eiger over im not so Sure.
I bought this Suzuki Eiger, almost a year ago, rear wheels locked up, but it ran fairly well. It was so bad that it took 3 Big Guys to get it on my trailer. All the parts were there it ran. He wanted 600.00 and I offered him 400.00. a plus it had the original Kei Hin carb on it.
You might ask, why would you want something so ugly, it is often referred to as the ugly sister to the King Quad. I actually like the Eiger I have this one and also a 2007. I have riden them before, they are strong a true beast, I am a fairly Big Guy 6' 3" 195 pds, and it fits me good, but what I really like is the wide foot print and low center of gravity , not so easy to turn over.
So I get it home and I don't have 3 big guys to help me get it off my trailer, but I do have a John Deere, hooked it up and drug it off the trailer,an afterthought I should have used a couple of furniture moving dolly's under the rear wheels, oh well. Maybe I didn't ruin the already stuck rear end or transmission I was sure which, I was fairly sure it wasn't locked brake drums, after all that they should have popped free.
This is what I have done so far. It's off the trailer I took the drive shaft bolts loose, they were tight, had to get a 3 foot cheater, I thought they were going to break. Got them out and now I can roll it around. I checked the shifter, this is a manual shift Eiger LTF400F. Foot shifter moved didn't seem to be going to any gear, but it was hard to tell, the shifter on the tank which has Low, High, and Reverse did not move. I took it apart and oiled it up good still wouldn't move. Thought the cable was stuck so I unhooked it from the linkage and cable moved freely. Looked at the linkage closely and it was stuck. I tapped it lightly, very lightly , with small hammer and it freed up kind of, but still stiff. I could tell this side cover had been off before and put back very sloppily. This is kind of where i left off except the plastics are all off, you might have seen me working on them in another post. Nothing I have done so far has helped, my next step was to take the side cover off the engine to see what's going on in there, but installing my Granite counter top, numerous honeydews, and the big bear kind of slowed down my progress. I did determine that it wasn't the rear end, that's actually what I thought it was going to be. If anyone has any ideas, they would be appreciated.
