Thanks for all the suggestions guys. I am still fighting this thing. Had to take a couple weeks off due to both mine and the wife's car needing some attention.

Back to the MXU. This is where I am to date.

I have connected a 12v test light to the plugs for the coil, and I get a flashing light when cranking. This tells me that the ignition module, and pulser unit is functioning as intended. Just to be safe, I tested the resistance on the pulser unit and it falls within specs for the MXU 250/300. As mentioned above I'm working on a 270, and finding information on that model seems all but impossible but it seems that many of the parts for the 250/300 are the same for the 270.

I bought a Lisle coil tester, and when connecting that inline and cranking the engine I get a pulse from that as well. This really threw me off, because I get zero visible spark when touching the plug to the block.

I did buy a new coil, and installed that today and frustratingly I am in the same boat. No start, no visible spark on plug. I repeated both tests using the 12v test light on the coil plugs, and the Lisle coil tester and both produce a pulsing light when cranking.

I actually have 2 brand new plugs, and neither plug produces a spark so I'm thinking that rules out a bad/faulty plug.

I really don't want to start throwing parts at this thing, but I'm running out of options.

Any suggestions, or thoughts would be greatly appreciated.

Thanks,

jpz, Do you have the service manual, if so take a meter and test individual component, you should be able to do it with ease. any component that fall out of tolerance will need to be change

Thanks for your input, I'll give the radio test a try in a moment! Like almost every Bayou owner mine has ignition issues, in my case weak spark or no spark, so I'm trying to rule out everything one step at a time. I ordered a NGK spark plug cap VD05F with 5kOhms resistance, it was like 30% of the OEM part price

did it solve you issue?

 I'm currently pulling my hair out over a customers 98  bayou 2x4 KLF300b. I've changed every electrical component on it twice and in a couple instances three times. Still no spark, I am baffled. Initially customer brought it to me complaining of a hard start no start situation and in fact, it wouldn't start. I changed the starter relay, spark plug,  CDI box, and starter circuit relay after which it fired right up ran very well but then started having issues with the neutral switch/light where it wouldn't come on and wouldn't allow it start or even turn over. I found in the wiring harness a loose connection, I got it taken care of and secured and that solved the problem. So now that it would crank up again and run fine I called the customer over to test it out see what he thought as I've never heard it run before and I wanted to get his opinion on how it was running. Customer ride it around a little bit pulled it back on my carport and turned the key off and said it was great, and had never ran better or started so easily, then we set up a time for him to come pick it up the following day and he left. Well where he pulled it on my carport and shut it off was in the middle of the carport so I jumped back on it to park it off to the side,  crank it up no problems put it in reverse went about maybe 18 inches and it stalled and ever since that point it has not had spark or run. I replaced the CDI box again with a better brand, I replaced the ignition coil twice put another starter relay on it and I've also changed out the stater and the pick up coil (pick up coil twice) and I'm just I'm lost I don't know what else to do to it. I've had this customers  four wheeler for four months now whereas he's a patient guy I need to get it out of here so I can move on to something else. I've seen dozens of threads across  different sites for off-road, 4 wheelers, ATVs, UTV's, whatever and they are all experiencing the same sort of issue but they never ever post hear the problem was or  the fix. So I'm hoping somebody here has a little bit of knowledge on this particular issue sent since it seems to be so widespread.  Thanks in advance for any help or suggestions.

I Have similar problem, let me know if you find anything...thanks

I was looking to buy a new ATV. 

I was debating between Polaris sportsman 450 and Honda rancher.

Polaris it a bit cheaper.

But can you tell me which one will have more demand on the used market? Which one will keep it's value better?

 

Let's say 3-5 years from now.

Personal opinion but I would says Honda without a doubt

Hi,

Sorry for asking (I'm struggling to understand some of your expressions, unfortunately I didn't learn english in school). What do you mean when you say that is turn over only when you put your hand over intake...is it starting only that way? Or is not starting at all?

Check your electric choke on the carburetor

their is a black cap on it and it is retain in place by 2 Philips screw. Take it out… turn the ignition on you should slowly see the needle extending. If not working properly change it it about 10$ or even go for a new complete carb kit for about 30$. You’ll find everything you need on amazon

I tried that and nothing came out the bleeder nipple and the reservoir so, I assume the mastercylinder is not pumping the fluid.

reservoir stayed full 

Look like you may have found the culprit

I was gifted four King Quad 300's, they were used to tow portable snow guns around the slopes. All of the plastics are trashed and racks bent up from rolling down the mountain. The lone Quadrunner is a 98, and will be the initial point of focus, as it reportedly ran before being parked in the field of lost dreams. 

Nice project, keep us posted with your work. Looks like a lot a fun coming for you!!!!

I seem to have no resistance at all on the rear brake pedal and no rear brakes. They were pretty good before I removed the right side crank cover. In order to get to the lower bolts of the cover, I took a piece of baling wire and wired the pedal in the down position. I assume, that caused at least, part of the brake problem. I can't see where fluid came out but, I did have to add more fluid. Added the fluid but still no resistance to pedal. Should I try to bleed the rear brakes? Thanks

Most likely a component that failed, hoses, master cylinder etc. Fill up fluid and try to bleed you’ll probably able to find the leak
