I got this 400, that wouldn't start. It would try, but wouldn't catch. I checked the valves and the L intake was tight at .002. The compression came in around 120. It didn't improve after a couple of drops of oil into the cylinder. So,I figured it was the valve causing the problem. So, I got the valves squared away, but it still won't start. I checked the spark and it seems like it's getting an intermittent spark. It fires a few times then nothing. If l let up on the button and then hit again immediately, it will fire a few more times, then repeat. So, what am I looking at as a possibility? Electrical issues are not my strong point. LOL
I have a 2003 Kodiak 450 that i purchased a while back with around 300 hours on it. It has never ran right from the beginning. Initially i thought it was just a carburetor issue because it was all clogged up from sitting for months. It has been cleaned, rebuilt, and taken off probably about 10 times troubleshooting this problem. I have quadruple checked everything including float height ect and it is set correctly, the jets are also brand new, needle and seat have been pressure tested as well. So after all of that I am convinced that the carburetor is not the culprit. I have an issue where the idle is very choppy, almost as if it is misfiring with a rich condition on top of that. I can use a brand new plug and run the machine for just a few minutes and it will be a dry and and coated in black carbon build up. The exhaust also has a strong smell at idle. I had trouble restarting it when hot for a while, but i adjusted the valves and it seemed to solve that issue. They were both way out of tolerance (tight). The weird thing is, outside of idle it seems to run pretty well.
So with all that being said I have ruled out the carb/valves/compression and moved on to the ignition and this is where i have a few questions about factory specifications. I guess the main question I have is, how strict are these tolerances? And could them being off by this amount cause the issue I am having? Do all three of these parts really need to be replaced? I would like to know before I spend the money on these new parts, and it not fix my problem. Below I will list what the specs were in the service manual along with the reading i got. This is my first experience testing ignition components. I just found it odd that all 3 are out of spec according to the service manual.
Spark plug cap resistance: 10 kΩ at 20 °C (68 °F)
My Reading: 8.90 kΩ
Primary coil resistance: 0.18 ~ 0.28 Ω at 20 °C (68 °F)
My Reading: Fluctuated between 0.4 - 0.5 Ω
Secondary coil resistance: 6.32 ~ 9.48 kΩ at 20 °C (68 °F)
Reading was within the specified range.
Pickup coil resistance: 459 ~ 561 Ω at 20 °C (68 °F)
Reading was within specified range.
Rotor rotation direction sensing coil resistance: 0.085 ~ 0.105 Ω at 20 °C (68 °F)
My reading was 0.3 Ω

Im new to the forum and the quad I just got. I want to change oil in in. Its almost impossible to find anything on-line. I know it takes 10w40 and know the oil filter location. What oil should I use? Is there a cross reference for oil filter. The closest dealer to me is an hour away. I have NAPA close and like the WIX or Napa gold filters. Also is where can I get a Manuel for it? Thanks
