Hey just joined the website and looking for some feedback. My 2001 Warrior 350 won't start. My dad took it out of the shed and wouldn't start so he sprayed some carb cleaner and it ran just really really bad. I took it to my powersports class in highschool and we have been trying to fix it ever since. We have done a leak down test, made sure the timing was lined up, check for spark, compression, replaced the spark plug, acid dipped the carb, and replaced the oil and gas. It would usually run for like 4 seconds than die and back fire sometimes. It was so loud it sounded like a gun shot. Checked the carb to see if all the factory setting were correct and they were. All of a sudden we can even get the thing to start for like 4 seconds. We decided to spray carb cleaner into the carb and into where the spark plug is but we still don't get any type of ignition which is weird because we do have spark!!! Anyone have an insight?
 
Same thing happened to my 89 when the trigger was on it way out. Get a multimeter on the stator and pulsar wires coming out of the stator cover. Turn it to ohms and let us know what readings you get.
 
petcock on the gas tank may be plugged up, did you make sure gas was getting to the carb/coming out of the tank? pull the fuel line with the tank outlet on and see if your getting gas. a/f adj screw may need adjusted as well. Also anytime you change oil you should check your valve adjustments and set to spec as well.

You got a gun mounted on that thing geeees? I want a trigger! lmao

We had a gas tank connected to it and had no luck. We were just trying carb cleaner with no tank. Do you happen to know the valve adjuestment settings or a manual with specs?

Did you test all of the wires coming out of the stator or which colors? Is this the pulsar I'm looking for?

Intake- 0.06-0.10mm
Exhaust- 0.16-0.20mm

Check your needle and seat. Is the bowl filling with fuel?

On the left sided of the bike (side with shifter) you will see wires coming out from behind the cover, that is what he is talking about.
 
You said you have spark, how do you know? What test did you do to determine that?

We kept the spark plug plugged into the cable and tested it on metal and we had spark. When its actually screwed into the motor though we don't know 100% if there contact with metal.
 
Your good on spark then. your problem sounds like valves are out of adjustment.
 
and in standard measurements the feeler gauges would be .003" intake and .005"exhaust. Those are equivilants to the metric feeler sizes above. easy to do and doesn't cost anything and IMO should be done with other routine maintenance at least to check wear and readjust but rarely is. Goodluck!
 
We tested valve clearance and it was to specs. Checked some of the cable.

There were three different cables:

Red and black 508ohms for resistance
Red and Green 4.3ohms for resistance

Then there was another cable where we didn't get any readings.

Sorry about the size of the picture but the cable next to the green and red one is the one with no readings
