110 ATV runs at low RPM

Recommended Posts

I have a 110 ATV which started fine yesterday. Today I go to start it and it only starts with the throttle wide open and then runs at low RPM, Unit is getting spark. Would apprecate any help I could get. Unit is a Chinese ATV.

I would double check that the choke is working properly. 

Then I would assume that the carburetor is loosing its fuel.  Where it’s going is the question.   

You could also have a crack in the rubber boot connecting the carburetor to the engine.

No rev limiter except the screw on the throttle. I have painted a mark where it's supposed to be and it 's still at that mark. This all has me wondering if weak spark could cause this issue.

I’ve had one of these bikes. Aside from the obvious things I pointed out in my previous post one thing I had to constantly do was change the plug.  Or at least pull it and clean it. You jogged my memory on this. 

Try this. Go buy two spark plugs.  Run the bike as it is and the next day see what happens when you go to start it.  If it does not start right up swap the plug for a new one and see if it starts up. 

Next day right out of the gate put a new plug in again and see if it starts right up.  If so the plug is getting fouled a bit lessening the spark.  Why ??? Could only be a few reasons.... 

These engines are not really well built and oil gets into the head though valve seals or rings etc.  Mine always blew a little blue smoke out of the exhaust. I was convinced oil was getting into the head.  Also I leaned out the carburetor a little and it helped but not too much where the engine ran like crap.

Maybe you can start there and see if the problem gets a little better with adjusting the fuel air screw first.

      Hello everyone! I recently purchased this quad for a mere 300.00 and it is pretty clean for the year. I bought it from a guy who bought it in a storage unit. He didn’t know anything about it. I got it home and noticed it did not have an ignition coil for the spark plug. I bought the ignition coil, a new battery, new CDI box, new starter relay, new safety neutral relay, new carb and so on... I got it to turn over, but when I pull the plug and check for spark I have nothing.. it has a non factory starter button that works when I push it and turns the engine over no matter if the key or stop switch is on or off..not sure what that’s all about, but it does turn over..just no spark at the plug. Any help would be greatly appreciated! Thanks!

      Got my Yamaha Grizzly buttoned up finally and went for a quick 2 hour ride in the power lines with my neighbor, who has a Yamaha Kodiak. We have access from his yard, which is nice. Was a beautiful day today to get out and will try to go more often. Ran into two other quad riders with a sportsman and I think grizzly. Also ran into a dirt bike rider. 😎

      First time using this forum.  Owned a Kawasaki dirt bike once, had no issues.  But I picked up this 4 wheeler at an auction.  They stated it ran, but only needed a battery.  Well I do not believe that was all true.

      Some pictures are attached.  Not sure why, but the whole air filter stuff was removed.  They had some small thing inserted as a make shift air filter.

      I purchased a battery to try this all out.  Waiting to return it and get the proper size, as it was too big for the battery box.  But here is my issue I had while the battery was connected.

      1 - The lights on the steering column did not come on.  Not sure if they work or not.

      2 - The starter solenoid seems to be bad.  I have a new one on order. 

      3 - In the pick, there is another rusted part.  Not sure what that part is or what it is used for.

      4 - What is the 12v rectifier?  square bodied part.

      So when I hooked the battery up.  Pushing the start button did nothing.  Pulling the cord to try and pull start, it turned, but would never fire.  I have put in a new spark plug as well, it looked worn out.  With electric start, I crossed over the posts on the start solenoid, it turned over, but would never fire and start.

      I have read a few other threads and it stated something about needed the neutral light on.  SOmething about a kill switch.

      Any help would be appreciated.

      Found some interesting news online when I googled Yamaha yesterday. Not sure when this went down, but Yamaha bought a percentage of Linhai (a Chinese manufacturing company) and are providing technology for Scooters, and more importantly for this forum, ATV's.

      Seeing as how not everyone can AFFORD the crazy prices that have skyrocketed over the past 15 years. Yamaha and Linhai are trying to produce a more affordable model by manufacturing out of CHINA! I found a pretty substantial savings at RidersWholesale.com over what they want you to pay at the local Yamaha Dealer.
      Just spreading the word. Let me know what you think about this. You can check out the Technical Specs Here
