Aerox wont start

[joemac2432]

Hi guys

looks like a great forum! My kid has a 2002 aerox 100 which he lost interest and its been left lying outside for months now in all the bad weather. He lost the fuel cap and had paper stuffed in it! I bought it off him to fix as it was a disgrace to treat it like this.....need help to get it going please.

1. Is there a special tool to take the plug out as there is a bar stopping the spark plug spanner going in.

2. How do you drain the tank

3. Can I use a 12volt bike battery to start this 6volt bike or jump start from the car?

I have the seat out and all around the petrol cap stripped.


Any help would be appreciated. thanks in advance

Hi, is it the air cooled one or not? this may or may not be relivant later, right mate, i've worked on so many aerox's i can whistle and the bikes strip themselves.
Start taking all the panels off start from the back to the middle.
Remove the foam seating and the bucket (riders) seat.
When removing the seat the cable can be removed from the bucket sets fork like lever and bent back when re-installing.
The fuel tank is under the foam seat, undo what you can see and drain it out and dispose of the fluids appropriatly.
Take it inside your house and let it dry out may take a few days.

You might also want to drain the carb, its a blade type screw on the float bowl, it will be the lowest screw, or if its like the new versions, its a push up valve, you just lift it slightly to drain.

Thanks tug. I cant see any rad so i guess its air cooled. Got the tank drained. I cant find the drain on the carb, cant see anything on top and theres 1 screw beside a plastic drain at the bottom which is really tight, its a star type. Is there some special way to get the plug out......I would like to look at it......

Anyway I put the tank back with new fuel and it wont start, not even trying.

The battery's knackered, thats with the car jumping it......

[TUG]

Batterys for that bike are cheap anyway, Check the fuse hasn't blown just to make sure. it should be in the battery tray.
It should be a kick start bike and electric, so if it won't start on the battery then kick is best, but you need to drain your carb and your petrol tank before you go any further, as your son has lost the petrol cap it will be full of water and it will never run correctly.
Also kick him in.

I did drain the tank and put new fuel in. I will have a look at the carb again and if its 2 screws that remove the bottom of it then i see them. Its the spark plug i cant get at...does it require a special tool as there is no room to put in an ordinary plug socket?

I tried kicking it for about 10 minutes, knackered now,lol, its easier connected to the car!

[TUG]

Halfords spark plug socket and a 24mm spanner i think will wip it off in seconds.
The 2 screws are to remove the float bowl, you dont need to touch them. Its the lower part of the float bowl you need to worry about unless your confusing the idle mixture screw and float drain screw up.
Take a picture and i'll show you.

I can only get a pic from the top, is it 2 screws at the bottom or one in the middle? Thanks for your help.

[joemac2432]

pic, sry not used to this forum,lol

[joemac2432]

There is one screw at the very bottom beside the plastic pipe which I think is the one needed. I cant turn it as it has been wrecked and no screwdrivers will turn it.....any suggestions guys?

[TUG]

That picture is the top of your carb. The float bowl is underneath. There will be a pipe or an outlet on it with a blade screw litterally right next to it, that is your float chamber drain. If its like the new aerox's then it will be a white plastic push up to open drain.

I only uploaded the pic incase u could identify which carb is was from the top. I found the screw beside the hose as I said but it has been ringed. The only chance to remove is probably on the bench. Should I remove the carb altogether but there are strange looking screws holding it in?

2002 aerox will be 12v not 6v

A type CT4L-BS is what you need for the aerox

Also you wont need to unbolt the reed block fron the engine to remove the carb, you should have a jubilee type clamp holding the carb to the rubber inlet block.

[joemac2432]

thanks for all ur help guys, does anyone know what size of torx i need to remove the carb as there are loads to choose from!

[Makaveli_Rydah]

Not sure on the size but a pack of assorted sizes should only cost a couple of quid .

The Aerox YQ100 is an air cooled motor for sure - only the 50's were LC ( which seems backward to me )

The plug itself should just come out with a ring spanner mate or better yet an open ender - that's what i used to use.

Be warned now they are horrible scooters to work on , i had mine for just under 2 years and they are a pig .
The plug gets wet in the rain if the road is wet and the bike conks out .
The exhaust was always snapping just below the manifold and it was forever blowing relay fuses .
Oh and i pretty much had to rebuild the top end every 5-6 months - this was on a scooter i only used for going 3 miles to work an back on each day .

You can buy a big set off ebay for a fiver, in a blue box its worth 10 times its weight in gold.
I agree, fix it and sell it.
Yes you'll need to take the carb off if someones stripped the head. a pair of pliers with a tight grip will undo it and bleed it.

Got the carb off, drained and refitted, still wont start after kicking it to death.....not even trying.....did yamaha design this kick for a 4 year old, i can just about get my heel on it! Im gona hook it up to the car but would have liked to have seen if its sparking ok. These things are harder to work on than a proper bike ffs.

Just discovered theres a plastic cover on the head....does this pull off, I have undone one clip below but it wont budge, I'm assuming this has to be off to allow access to remove the plug?

[TUG]

Its to create a enclosed space for the fan to cool the engine (air cooled) and they're a pig to start when the carb has been drained or is new, take the air box cover off, air filter out, buy a can of brake cleaner and spray near the bike as the engine cranks, you have replaced the battery havent you?

I had the air filter off and replaced the battery. I still don't get the plug bit, do I remove the cover to get at the plug? How does it come off? Another bit i don't understand, where do I spray the brake cleaner, into the carb? I'd like to clean or replace/heat up the plug to give it a better chance of starting or do u think I should leave it alone?

[Makaveli_Rydah]

[joemac2432]

I took the carb apart and cleaned it, its defo fine. Yours must be a different design as you cant get a spanner near it as there is only about 2 inches of the ceramic showing, the head covers most of it up and there's a bar right facing it that stops a normal plug spanner going in, thats why i think you need to remove the plastic cover but i found one clip holding it and have pulled really hard but it wont budge.

Theres plenty of compression, the bike was fine until he lost interest and left it out with no fuel cap, but this has been drained and new fuel put in. I will take a pic tonight and show u what i mean about the plug. I think if i had this out it might have a chance........its the plug thats doing my head in which should be a 2 minute job................

[Makaveli_Rydah]

I assume this is what your talking about ?

This is how mine looked and it was an 03...
