Honda CG125 Choke

[Guest]

Hello. I was wandering if any other CG fans/users could help with this problem or question.

Basically, about a week ago I bought a Honda CG125 2005. It seems all to be working without a problem but I think I have a problem with the choke.

I'v been getting my information from this site about it but want to get someone elses view on the matter.

Right, so I go to start the bike and obviously need to let the engine heat up. Now I'v been assuming that for the CG choke, the level facing down meant it was On as that's when it started but apparently that's not the case. The website above has been telling me that the lever facing up means the choke is on but it never starts yet it'll start without the choke perfectly first time then heat up and start.

I am a little confused as I'm not sure if I'm doing something wrong or my bike is different. I'd appreciate any help who might know about this or any other CG fans with a 2005 model.

Thanks.

have a look on the side of the choke lever carefully is there an arrow poing up or down on it if there is then that would normally be the direction to put the choke on.also if it is an older cg it might of had cab messed with and fuel mixture reset so that it doesnt need choke to start it and by putting the choke on you are flooding it

Had a cg, 06, all the way up is choke on, middle is half, and bottom is none,

i put it to full when starting the bike, then straight after goes to middle to warm up

So you'd put it to On when starting the bike then middle?

What's the middle for? (still new to bikes)

For my CG, it won't tick away with just the electric start when the choke is on, I actually need to constantly rev it or it dies.

If its Half Way or Off then it starts perfect first time with just a push on the electric start button and it'll just tick away heating up the engine. Is this normal or should I be worried about this?

Also, I did not notice any arrows directing which way on and off is.

if it is starting with the choke set half way then dont panic or worry some old hondas are like that you will mor ethan likely find once (if) the warm weather gets here it will not need any choke at all to start

I had a CG, choke down is off as been repeated, if it starts without choke then it starts without choke. If it runs fine when your out on it then its a case of if it ain't broke don't fix it.

You may find you need choke on a very cold day, I found mine started with no choke 95% of the time.

Sorry as for asking what the middle does, you need to know what a choke does.

In the carb, fuel and air is mixed into a kind of vapour, (droplets of fuel mixed with air) when a bike is cold, this fuel sticks to the inside of the carb and cylinder reducing the concentration of fuel in the vapour. This effect is worsened with cold weather. This can mean there isn't enough fuel to start the bike. What the choke is, is a butterfly valve inside the carb, behind the jets where the fuel gets injected, but in front of the airbox. All a choke does is 'choke' or restrict the amount of air that can pass through the carb, increasing the concentration of fuel in the fuel air mix, compensating for the fuel lost by sticking to the internal components and allowing the bike to start.

If you removed your carb you would be able to visualise what I mean straight away. You can see the valve and its positions in relation to the position of the choke.

Now choke on is the valve closed with a small apature for the air to pass through,

Choke half way is the valve on an angle, so it causes some resistance to the air, but less than the choke closed fully.

Choke off puts the valve on its side so it's not restricting the flow of air at all..

Hope this helps you understand what it does, and why it's not a nessesity, but an aid to start your bike if it needs it.

Choke fully on... If it wasn't it would be flat, causing minimum disruption to the airflow, the part your looking at fixes onto the airbox, (air intake) and the jets that provide fuel are behind the choke plate

Thanks for the posts guys, really appreciate it.

My routine for the bike now will be putting the choke on half, letting it warm up then dropping it to off and taking her out. (hope its right at least)

Edit: Oh sorry, one more question for you guys. When I'm not using the bike, should I have the choke on or off? I currently keep it off but I'm just curious on what's best for the bike.

[eastanglianbiker]

leave it off not that it makes any difference

[Karimura]

sorry for late reply,

yeah i still had to put little rev on otherwise mine would die out too,

had to keep revs till it was warm, then put choke down, only keep revs going for like 10-20 seconds till it gets warm

hi, could anyone explain how I stop the choke coming ON while I'm riding, it should stay down OFF when engine warm but mime seems ro jump or vibrate into ON position which means pushing lever down while riding, bit of a hinderance at best. Please help eith any suggestions to fix this ?
