New gio x35 keeps stalling...Help!
 

Help! Just bought an x35 Friday. Took it out Saturday and can't keep it from stalling. At first it only happened when I reached high acceleration but after a while it barely stays running. Once it stalls I have to wait a minute for it to start again and the problem begins all over. What do I do? I'm no mechanic.

Tank not venting?

Does the choke seem to be working ok? Did you buy it from a dealer already assembled or get it off the auction and put it together yourself?

Since it will restart after waiting a minute, I'd be inclined to check the fuel cap, like Kato says. Is there a short vent hose on top of the fuel cap? If so, try removing it and see if the problem goes away. Be careful, because gas might squirt out of the hose. I just use a length of vacuum hose and direct it into the steering stem.

If that doesn't fix it, does the choke have multiple settings? Does it make any difference where the choke is positioned when you have trouble?

BTW, it doesn't matter what the plug says on it, I'd promptly change it for an NGK from Canadian Tire. Several of the plugs in China bikes have been fakes.

Hoe would I know if the tank isn't venting? I bought it assembled. I am out on it now and I tried turning the carb adjustment screw on the right side. Seemed to improve slightly but the problem is still happening. I think I am going to tinker more with the idle screw. Any suggestions?

Ill try the gas tank cap hose now. The choke seems to be working.

If simply removing the hose doesn't work, try removing the entire gas cap. Please be careful when testing.

The cap might have a check valve in it that is stuck, perhaps due to some plastic flash from the mold process.

I was going to suggest loosening it some but not taking it right off, but either will work. :) ... probably better to take it right off but it could be a bit messier.

How is your idle adjustment?

I adjusted the idle and it seemed to improve butit went right back to the same problem shortly after. Switched the apark plug and same thing. Loosened the gas cap , removed the hose, didn't pull the cap off though as I saw gas squirting out when riding with the hose off.

Not sure what else to do. Going to bring it back to the guy that sold it to me and see if he can figure it out I guess. Not sure if he will help but I hope so.

One of my Lifan Hondoids had a kinked fuel line that slowed flow enough to cause the same issue. Check for that. It sounds like a fuel flow issue to me.

Although I can't test this right now it sounds like it may be hopeful. I just saw a bend that might be considered a kink. I'll check it out tomorrow. Thanks.

That could be it. Replace the fuel line and add a small generic filter while you're at it. $5 at the parts store and you will be set. :D I hope...

I've also heard of bits of plastic from the tank ending up in the fuel line. Like Doc says, some new fuel line should cure it, and an inline filter is cheap insurance. Just ask for a USA-made filter if available at your local bike shop, because I had a Chinese one come apart on me. Hot engines and pouring fuel are a bad combo. 8O

I use the blue snowmobile fuel line from the bike shop; I can see fuel flowing through it, and I figure it's gotta be good in colder temps.

Do what W&G says. Best to upgrade now to avoid the inevitable china rubber failure. Often the lines are too long and kinked.

Also make sure you oil the air filter as this probably hasn't been done yet by the dealer.

China rubber failure 8O

Where are Trojans manufactured?

no body suggested removing and cleaning the carb ? could be something simple like dirt or flash in the carb bowl that gets sucked into the main jet and causes it.. then after sitting it falls out and goes to the bottem of the bowl.

I brought it back to the dealer I bought it from and he will have his mechanic look at it in the morning. Ill let you all know what comes of it.

Thanks. Keep us in the loop. The answer will help the next guy.

sounds similar to how my X33 was behaving before we found that yellow creamy slime in the carb. bike would barely idle, and die when revved. then it would get to the point you would have to let it cool down before it would start again.

It ran better after we cleaned the carb but GIO eventually sent me a new carb and gas tank and now it runs perfect.

I can't remember if you said in your other thread, did you ever figure out what that slime was?

Yellow creamy slime, hmmmmm, could be the inners of a boston cream from timmies?

Mmmmm, Timmies. :D

Except, make mine a Maple Dip.

odds are the yellow stuff was gas from when the company who actually made the bike, did the testing on it before shipping it out.. to make sure it starts up and what not. i say this cuz when i bought my quad used from a guy on cl the first thing i did was clean the carb and it had a dried crusty yellowish crap all over just the bottem of the bowl. 10 minutes with some carb cleaner and a old tooth brush took care of it.


sometimes these china bikes and china quads sit in a warehouse for god who knows could be a week to a year before they get sent out to the other people that sell them online and in stores

I saw a video of a factory in China and they tested the motors out of the bike. It was a contraption that had it's own carb and exhaust. They just popped in the motor and the arms with the exhaust and carb would swing in and the motor would fire and it would be on to the next motor.
motor wasnt tested in the bike at all.

no update yet folks other than the dealer has it. i am betting it is a kink in the tubes as they are crazilly long...we shall see soon.

still the motor was tested, one place might do it that way, another might hook up the carb and exhaust that are going to come with the motor

Got a link to that Cal?

No we never did figure out what it was but it was not old left over fuel.. it was not oil based at all. it seperated and floated like water in fuel.

I'm pretty sure it was the filling from a boston cream donut.

Lol! Must have been :D. Well have to leave this one to unsolved mysteries... More than likely was some sort of mold release or something from the manufacturing process. Good that John sent replacement parts though, he's always been good to me as well, shipped the parts with no questions asked.

Cheers,
Stew

Hmmmmm...... timmies in china?, i'm going to have to look into that one.

I'm curious, did the dealer puzzle out what was wrong with the X35?

Cant say for sure what was wrong but i think the problem is gone. The dealer couldnt duplicate the problem and so we suspect it was one of 2 things:

1 a kink in one of the fuel lines restricting flow
2 something from the manufacturing process that needed to make it through the lines after a few rides


If it happens again, he gave me a replacement coil. Ill update you all in the spring.

Later folks

Thanks for the update Frank. Glad to hear you can ride again. :D

250 DIRT BIKE STALLING
 

On a lot of the GIO bikes the fuel hose under the seat gets pinched off .. cheap rubber I always install the good clear plastic line.. and I even check when I put the seat on to make sure it is routed away from the pinch area... this is the main problem... it everyone would keep the problem small before the RIP off the carb and go into a main rebuilding situation then it would not seem so bad of a problem.. alot of people when they assemble their own bikes ( out of the crate..) They always forget to unkink the air breather line from the rear of the motor ( vent tube) this will pressurize the motor and blow oil out of the left side crank seal... I have had several buyers call up with that problem... when I tell them to check that.. they never call back... too embrassed..

sorry forot to add my signature as requested by management

Cool. that sounds like a plan. Thanks for the tip. I will check it out to be sure. I think i like the idea of repalcing the lines as i don't want to be out in the middle of no where and have this happen.

Replacing the fuel lines is a cheap mod. The clear/translucent helps to verify fuel flow too.

A decent quality fuel filter doesn't cost much more than a cheap one, and they're less likely to fall apart on you. We had a cheap filter separate while on the trailer, and if it hadn't been for the closed fuel valve it would have drained the tank.

If that happened while riding, fuel would be pouring onto a hot engine. 8O
