Since it is a new carb it should be ok, but check to be sure fuel is getting to it. Tank valve could be blocked or partially blocked.. crap could be in the line , if you have a fuel filter on it , check it is not plugged . For those working on cleaning carbs and jets : instead of using a piece of copper wire or a strand from cable , go to a welding supply store and buy a set of "tip cleaners" they will have various sized cleaner wires that fit pretty much every size orifice you'll find in the carbs. They're much more convenient and better for the job.

Did you try the starter fluid test just to make sure its not fuel starving? You had mentioned that it would start and then die out, that's usually lack of fuel

Sounds like ajmboy is right on point with this. Question why did you change cdi, stator etc? No spark issue? Reason why I'm asking I went through the same problem with my electrical system "Yamaha" and replaced the same components. Thanks to the help of this forum. However after I Installed the new stator the bike started right up but seemed to run really weird, starting not starting etc so I put the old cdi back in and the bike fired and ran perfectly. Turns out the new cdi did not work correctly with that bike even though it was for that bike but not an oem part. And did you change the coil going to the plug? Shot in the dark but I found mine cracked. Just a few points to check out. Having said all of that I'm going to agree on the carberator problem. I recently took mine apart twice and found the first time I missed a few spots while cleaning. Def take that float needle out and clean it good and a trick I use is taking an old bicycle brake cable and separating the strands cutting one strand off about 6 inches long and use that to get inside the small orafaces of the carb and use the small cans of compressed air that you buy at any local stationary store to blow out he small ports it comes with the small tube to attach to the nozzle. Hope this helps. Good luck.

I have not tried the starter fluid yet. I did test ohms and it was good. And yes I do have spark. By the way, thanks for all you guys input.

How did you check it? Has to be ohms test not voltage. If you go back and look at some of my old posts I asked the same questions about the stator testing. If someone jumped started that bike or welded on the bike as I learned here on the forum can damage the stator. It will still make voltage! Don't be fooled. But simplify this entire spark issue by checking for spark. Pull the plug put it on the ignition wire and test for spark while cranking the engine. If spark is there that's a huge relief!

I had one of these Yamaha Kodiaks but a 450 and after it sat for a while, the float pin in the carb became corroded causing the float to be stuck up. It would startand run out of fuel in the bowl. I would check your carb. When it's just cranking, spray some starter fluid into the air intake. If it starts, it's fuel starved. * Topic moved to Yamaha ATV forum.

Make sure the quad is in neutral, check there is power to the ignition switch, then the process of elimination starts at the battery positive and ground and works through the circuit. You can quick check the starter by running 12 v directly to the terminal momentarily to see if it spins over ( assuming you at least have power to the lights and indicators) Usual problems are bad grounds, broken wires and corroded terminals, or defective relays. Check in that order. Electrical problems can sometimes be a real PIA to trace out .

Did you also change the oil and filter?.. Water vapor could be coming from water in the oil boiling off and entering the intake through the breather tube for the crankcase. Try adjusting the idle air screw and or the needle valve settings. Bogging on acceleration sounds like it isn't getting enough fuel (running lean) when you open the throttle.

I actually came across that thread before I posted here. None of his solutions made any difference on mine. I found the problem this mornin, apparently the BRAND NEW (like installed less than 24hrs ago) intake manifold had a gash on the bottom end of it on the rubber. Never thought to look at it since it was literally brand new. Just got off the phone with the parts company and have a replacement on the way. Goobered it up with JB weld for now so my boy can at least ride it for a bit. Just waiting for it to cure and hopefully she'll ride like new. Thanks though
