knock
hello... I had this problem with a motor as well... torn it down could not see any thing.. switch the complete motor from a brand new unit... ( I am a dealer so I can do that )... and it did the same thing... I was stumped.. then I realized I used the carb that was on the one that was making the noise on start up,,.. only when you tried to start it.... the carb was switched with the one that was on the other atv... perfect... the throttle plunger was set to high allowing it to get too much fuel on start up... so I lower the plunger .. ( the one on the cable).. so it would not draw as much fuel on start up... ( PERFECT.. )
WHEN you try to start it and give it throttle as some require it... it would over fuel and KNOCK on start up,... like pre-ignition.. stupid problem.. drove me nuts.. so lower you throttle setting.. and DO NOT GIVE IT FUEL ON START UP.... I am sure lots of atvs have this problem.. I now notice this on some atvs. as people twist the fuel trying to start and it over fuels the motor.. and either you flood the carb and sparkplug... or it knocks too much fuel in motor.. try it and let me know..

Hey everyone, sorry for the delay in replies. I went to put the washer on the head bolt that I forgot to put on, and I found I had stripped the bolt. I ordered new ones and had to wait for them to get in.
After replacing the head bolt, I pulled the carb out, reset the throttle cable, and ran the main sprocket a few times to make sure the clutch was free. She wasn’t happy, but I was able to eventually get it started and idling! It took a couple hours to secure all the wiring harness, attach the body, attach the seat, air up the tires, reattach everything else, and get it ready to ride. I took it for a 60 second spin! It had a weird smell and I need to tune the carb but it seems to be nearing trail ready. Thanks for all the help! |

If you look real hard at the video, the chain starts to run backwards when the "event" happens... sure your timings not too far advanced?

We’ll it started without the chain! Sounds like it wants to run away and then after I killed the power it smelled like something burning…. Thoughts?

I have no idea where there should be a shifter. Since these small ones don’t have reverse I just figured they are automatic or a clutch that doesn’t need a shifter?
Good eye, I didn’t see the drip at first! After inspection it looks like one of the head bolts is missing a washer and I think that’s where the oil came out…. As for the exhaust, it is attached it’s just on the other side from this video. The throttle is not stuck open. |

Is this where the shifter should go? It doesn’t look like it would connect to anything? Is there supposed the be a shifter? This is on the left side below the sprocket basically.

It's the short shaft sticking out the left side with splines on it.

Pull the air filter off and look at the carbs throat. You shouldn't be able to see through the carb; the sleeve should be all the way down. If it's not, then there is something keeping the sleeve up. It could be installed backwards. It's easy to do. Even small ATVs should have reverse but not all. I'll check tomorrow and see where the shaft comes out on my 125. On the video, it looks like there's a round hole below and rearward of the stator cover. Is there anything there?

I don’t think my photo uploaded. There is no shaft sticking out!

Which way is the sprocket turning in the last video with the chain off?

Thanks everyone for the replies.
Yea, that hole is where my other 110 shifter is coming out of, but this one doesn’t look like it leads anywhere. I can try to upload the picture again tomorrow but it just looks like a hole. I don’t see it connecting to anything or looks like it’ll move if there were a pedal in it. What should the shifter connect to in there? If there were one, shouldn’t it go all the way through to the clutch? I can look at the throttle cable tomorrow too, but I have done a bunch of carb work and highly doubt I did it backwards. Although it could be sticking up. |

Hmm not sure, I shut it down quick because I don’t want to damage anything any more. I’m thinking most of you are right with a clutch problem, but idk if there’s suppose to be a shifter there or not. If there is suppose to be something there, that seems like a very obvious fix. If not, I’ll have to open her up again and…. Idk?

Does this link work for the picture of the gap where the shifter normally is? https://ibb.co/cTPFHXb
