ATC 110 losing power

[Moonfrog_411]

I have a Honda 110 ATC that seems to bog down after about 10-15 minutes of riding. It runs fine then all of a sudden you hit the throttle and it wants to die out. Once it sits for a few minutes it will fire right back up and can be ridden for about 5 minutes before the same thing happens. It has good compression and spark. Cleaned the fuel tank, carb, put new filters and gas lines on it but didnt help. I did notice that the gas is not flowing freely through the filters. (bought at O'riley auto parts). Have to squeeze the gas lines for the filters to fill up(maybe just running out of gas??) Is there a certain type of filter needed. I also heard it could be the gas cap not venting right? Just trying to figure out what direction to go in to try and fix it - fuel or electrical. Any help is greatly appreciated.

Thanks

Ought to get a strong stream out of the hose, Id look at fuel system. The filter should flow just hanging there. Compare how much it flows in 10 seconds without the filter, then with.

I had a problem like that with one of my old TS125's. Ended up my petcock had a mud wasp nest in it :lol:

[Moonfrog_411]

Guess I'll see how the gas is flowing through first and then check the petcock.
Thanks for the replies....

Try lettin it flow with the gas cap on and then with it off, you might have a venting problem with the cap. I see it alot with lawnmowers. Will run great for a while till you get vacume in the tank, let it sit and then it will start and run again for a little while.

[Moonfrog_411]

So if it is a venting problem, what do i do? Buy a new cap...

[oddball3]

Yes, buy a new cap. Iv seen the caps with alot of rust in them also that they wouldnt vent right.

[Moonfrog_411]

Thanks for the help.
I will try to get to it tonight, the weekend for sure.
Thanks for giving me a place to start...hope it fixes it

I had a Quadsport 230 that did that after I didnt put a part back on at the point where the muffler goes into the motor. I forget what it was but I remember thinking it unimportant.
It would run till she got hot, then it would start to sputter and stall. It would take about 15-20 minutes befor she would restart. It took a week of trying all the above stuff before I decided to put that small part back on it.
It ran great till I sold her a few years later.
Just a thought in case you messed with the exhaust and its missing a gasket or whatever. :beer

[Moonfrog_411]

Cant say that I have messed with the exhaust but i will take a look anyway. The more help the better....

[Moonfrog_411]

Can anything electrical cause this problem? CDI, coil, stator....just in case everything else checks out ok. Like if a wire is cracked or frayed it will heat up and expand causing it to lose connection and once it cools down again it will be fine...and so on.

Is the inline filter made for engines with a fuel pump? I know that may restrict the flow of gas, but you were saying you had the sqeeze the lines to make it fill the filter so the petcock is probaly clogged of rust or something. try that first, if it still doesnt work, it could be the cap not venting, take that off and run it for a bit with something over the hole just so the gas wont come out.

[Moonfrog_411]

Not sure, just went to the part store and picked out two small fuel filters. Guess thats not the best way to do it. I cleaned the tank (pretty dirty) but didn't mess with the petcock. I'll start there.

Thanks again guys for the help.

[Yamahauler]

Yea, take the petcock off and blow compressed air through the opposite way the gas flows. Switch it to reserve and blow through again. A bunch of crap should come out. You say your tank was dirty, I'll bet it's your petcock.

[Moonfrog_411]

Does the petcock have any type of screen in it? Should I replace it or just clean it real good. After cleaning the petcock itself.

[zoomerman]

yeah it has a little sceen it in i would think that all you would have to do is clean the petcock and screen

[Moonfrog_411]

Will do...

have a good one...time to get the heck out of work.

[Rm250RF900R]

Yeah the petcock has a little screen filter. If its rusted out or missing i would replace it. You wont need a fuel filter if you have a petcock filter. Unless you want double protection. But wouldnt that restrict the fuel flow even more? :confused:

[Somekindofjerk]

Believe it or not with an engine that size a good oil could be all you need. i used 15-40 but it would randomly shut off somtimes, i figured to hell with it i only drive it in summer anyways, so i baught single weight oil like 50-80, that helped me allot. allso, if you take appart your carb intake port off(would be the two small philips screws) and clean the screen out you might have some luck. by the way, dont mess with the electrical, 9/10 times youll break something expensive.

[Yamahauler]

I wouldnt worry aboug the fuel filter restricting flow, unless it is one made for fuel pump bikes, then you may have some restriction, but just go and get a inline bike filter, I have a briggs and startton on mine, It for a lawn mower, but works anyway.

[oddball3]

There is no diff in the fuel filters from having an engine with or without a fuel pump. My sleds have fuel pumps no diff in filter. A smaller micron filter would restrict it alittle, but nothing you will notice. I work on power equipment and with or without a fuel pump its the same filter.

Well then the guy at Yamaha has been feeding me BS :lol:

[New2ATC]

my 125M is doing the same thing. I will have to try these mentioned tricks to see if any work.

I was buying my inline filter at Advance Auto, and there was one for use "with fuel pumps" and one was just a regular filter.. no special applications were mentioned. The one I got is about a 1 1/4" long cylinder 1/3" or so in diameter, is clear, and has a little mesh screen inside of it. The one for use with fuel pumps was about 3/4" long, 1" in diameter, and red so you couldn't see inside of it. I don't know what the difference is. The only thing I could see was that the one for use with fuel pumps was actually cheaper, and the shape was much different. I have no clue why you would shape a fuel filter like that though..

And about the problem.
My first guess when I read your post was that the petcocks "filter" was clogged. That is the most likely culprit. Just take off that bottom piece (there should be a hex-head on the bottom of the petcock and you twist that portion off), and clean out the screen. Then blow compressed air through the outlets and inlets to get out any other gunk that may have came from your tank.
And are you using pipe clamps to hold your filter onto the gas line? If you are, you may be having the same problem I did. When I put on my fuel filter, I tightened the clamps down as much as I could, which was a mistake. I actually tightened them down so much that it squashed the end of the filter where the gas goes in and it just let the gas dribble into the filter, so it would stall after very little riding.

[oddball3]

The only thing I could guess that the filters would be different for a fuel pump and fuel injection system, is that the filter can hold the high pressure of the fuel injection, they still flow the same.

Exact same thing happened to my 110. Bunch of rust got into the petcock and blocked the holes partially, meaning I depleted what was in the carb faster than it could be restored, meaning 30 minutes of riding and it bogged out. I found that taking the cap off and blowing into the tank would let me ride for another 15 to 20 minutes until it bogged again.

hey i just bought a 110 and it didn't run so i took apart the petcock and cleaned the screen and made sure the petcock worked while it was apart by turning it to res, them on and it flowed really good so no problems there. then i proceeded to the carb two #10 nuts and the throttle cable and she's off. two phillips screws holding the bowl on and it's off. remove the drain needle clean blow though reinstall. remove dthe jets and the float and viola! there was the problem stuck needle, i soaked the entire carb in gas then took a needle and made sure there was no crap blocking nothing , reinstalled and she runs like a charm. hope this helps and gives you hope. oh and also check to see if anyone has replaced the fuel lines and made them too long. if there is too much hose where it has to make a sharp bend chances are it is pinching.
