Need-help-with-quads

Yea I cleaned out all the intake boots and hoses and had cleaned the carb before I put the new box on, I’ll try cleaning it again though and let you know what happens

So I picked up a 1995 Yamaha warrior a while ago and it ran decent with quite a bit of power, I was able to wheelie like nobody’s business, but I noticed that the air filter box lid had bunch of holes drilled in the top and hole in the side, also the air filter itself was serving no function and there was a huge rip in it. So I got a new air box and new filter and when I installed it, the quad lost all power and acted like it was cutting out for split seconds at full throttle. For reference I think it was running rich before because it would backfire a lot so I think it’s just restricting air flow, but how would I adjust to that because I tried leaning out the carb as much as I could but it didn’t seem to do anything unless I put the other airbox lid on with the drilled holes. any help would be much appreciated Also even when I put the old lid on, it seemed like just the new air filter gave it enough restriction that it still wouldnt run right

Ok the switch seems to be fine after doing that

Oh yea I was getting 12.25 from those but when I cranked it the minimum voltage read that for some reason I guess I’m not really 100 percent sure how to do the record feature but it was reading 12 when it was off And I’ll clean up the switch

Or do I need to do that again but from the actual battery terminals?

Ok so I tried my best with what I could find, so on the ignition switch I tested the negative side and the positive side, the negate read .6 something and the positive read .8 something and this was when I cranked the engine, I will send a picture of where I connected the probes to make sure I did it right The middle left wire is the negative and the middle right is the positive, first I connected the negative probe and then I connected the positive probe to the far left, which should be the signal that lets it crank and then I swapped it with the positive to test that, is that the right way to test it? Also when I cracked it I hit record on the multi meter and that’s how I got those readings they were the max

Alright how would I go about testing the switch?

Also the spark plug is white and checked the switch and it looks fine

Ok so o haven’t messed with the switch yet but I looked at the spark plug and it was wet so I had an extra one so I put the new one In and it rode great, but about 2 minutes in it started riding badly again so I took out the plug and the new one was wet so is it flooding somehow while I’m riding? Float maybe? I will check the switch though just to make sure that it’s good

Yea it was just the key switch I don’t really mess with the other kill switch and it doesn’t really move but I could try a different kill switch

Ok so it’s being weird last night I messed with it I pulled the carb and cleaned it and replaced the plug and needle and it ran like a dream and it went full speed and it had a lot of power so o had a buddy of mine come and check it out so he gets on it and it goes right back to running like crap so I don’t know what’s going on, did dirt or something somehow get in the carb that fast? Is the choke sticking or something? to clarify my buddy came and looked at it about 40 minutes after it was going good so I don’t know what happened I’m lost

Weird because there was two marks on the flywheel and they were on opposite sides, the one put it to had a capital t and a line the one it was at before was just a regular line, but anyway everything else is good I got an oem carb needle so maybe that will fix it if not I’m gonna sell it as is with a box of parts

Ok so I fixed the timing and it runs the same so I’ll go through everything else tomorrow

Ok I just checked timing and it 180 out of timing I’m not sure how I did that but whatever I’ll fix it and rider her again

I’ll go through timing, valve and the carb but here’s the video I took before I sent that last message Quad.MOV
