Can someone help me please? Bought a CG -

[CG_owner]

Hi everyone.

I have recently bought a CG125, i am going for my CBT next week, so was just going to use the CG125 on my land in the time being as it is my first time i have ever been on a 125 bike.

I have had a moped before, but there is a lot more to the 125cc than the 50cc.

What do i need to do exactly to start it up and get it going? At the moment, when i start it, it cuts out after i have kick started it, if i dont give the bike continuous revs, is that normal?

When i start it, do i have to hold onto the breaks or the clutch? and then kick start it, or...?

Sorry for all the newbie questions, like i say, im new to bigger bikes than 50cc, so i really do appreciate any help.

Thanks.

you need to add a bit of choke when you start it from cold, leave it running for a while on the choke until the rev's start to rise then slowly decrease the amount of choke untill the bike it ticking over on its own.

the choke is a little lever near the carb.

if it still cuts outs out when it not running on choke you may need to increase the idle speed, there will be a screw on the carb for this im not sure where exactly off the top of my head, but you should adjust it till it ticks over with out choke at about 1000rpm

you should'nt need to pull the clutch in to start it, or at least i didnt when i had my CG

Thank you.

Have just tried that.

From the choke off position you can raise the choke 2 notches.

On the top choke position it cuts out straight away and doesnt idle.

With the choke in the middle position (between no choke and full choke) the bike idles for a little longer but then cuts out about 10 seconds.

Thank you for your help.

Theres a chance the idle is set wrong, if you start it up with 1 notch of choke, hold the throttle 1/4 - 1/8 open for a minute and turn the choke off (down) and then let the throttle go back to the closed position then does it die in a sort of stuttery manner, or does it sound more like its bogging down (sorry, complicated and badley worded question to ask a noobie)

Give us some details of the bike, it's unlikely you've bought a dud, but a bit of background of it would make things easier. And also the obvious one, does it have petrol, how fresh is it, and is the tap turned on.

[TheDonUK]

To start on a cold ish day i do:

Lights off - Full choke - Tiny bit of throttle - Starter - As the revs try to build higher due to the choke turn it down, and then turn it off as you ride away, take the bike out for about 10 minutes and then come to a complete stop with the bike in neutral and see what revs the bike idles at

And yes as tristan says, make sure it has enough petrol and that the fuel tap is set to "ON".

[Fnatic]

Get someone to hold the bike and keep it going and you adjust the idle.

I would recommend cleaning out the carb, main jet and a new spark plug but I'm not sure if you would know how to do this.

Definitely a simple issue.

[CG_owner]

Thanks guys.

Seems to start better with the choke in the middle - when the choke is in the top position it doesnt idle - it just stops.

Tristan - thank you for your advice - i kept the throttle fairly low but some revs after starting the bike with half the choke (half notch) for 1 minute and the bike then idled fine, i.e. didn't stop.

It was then my changing gear technique which i havent a clue about which made the engine cut off.

So with the choke on half and the revs kept fairly low, but still some revs there, the bike seems to idle fine after a minute or so.

Any hints with gear changing guys lol.

Thanks for your help and patience, i know it is probably testing with a newbie.

(is this for real?)

You need to learn to feel for the "biting point" ... i.e., the point at which - when you are in first gear - as you increase the throttle, the bike starts to move forward.

If you're having problems with the idle and have to keep the revs up, just remember to let the clutch out carefully

once warmed up and running without choke put the bike into first, then slowly let the clutch out till the engine note dips
hold the clutch there
that is the biting point

to move forwards let the clutch out a tiny bit more and it will pull forwards

adding throttle just makes the bike pull away quicker



you could book an hours lesson with a riding school to get the clutch and gears sorted
edit
CBT next week will cover it all "must read OP)

It might be an idea to give us a clue as to where you live, you never know someone may volunter to come and give you a hand

Thanks for the help guys - i know some of it must seem very basic - but i am a newbie to bikes and we all have to start somewhere ey.

[Fnatic]

I agree.

Some people start younger, at like 8 with a field bike. Some of us start at 16 with a 50 and some of us start at 30 with DAS.

Doesn't matter, we all have to learn. In the last year, owning a Chinese bike and a Italian bike has taught me a lot about maintenance.

A lot of people come to BCF and get abused for asking for help because they ask in the wrong way I think. You have come on and asked politely So stick around...

I remember buying my 1st bike a CG , 4 years ago and struggling to start her.

I also remember bricking it before going to work on it for the 1st time.

And on my way home, instead of turning right, I would ride ahead in to a car wash place, get off it, re-positioning it and then set off again.

After a couple of weeks, I did a 70 mile circuit up to Skipton over the tops to Harrogate and back. I learned how to ride on that journey, i'll never forget it.. By the end I was filtering through traffic and over the tops I was leaning in to bends, it had all clicked.

Good luck with biking.

CG shouldn't- depending on how it's set up of course- need full choke to start unless it's properly cold. Certainly in this weather it wont. Mine usually starts with no choke.

Yes but as we all know CBTs are rubbish.

If I didn't know already I would have no idea on how to use a geared bike from my CBT, it was all on a Baotan scoot that topped out at 25mph.

when it is running:

Clutch in
1st gear (click it down)
clutch out very very gently all the way not just to the biting point
then when you want to change gear, clutch in, drop the throttle and gear lever up into 2nd, clutch out in the time it takes to say bish bash bosh.

When braking remember to pull the clutch in or you'll stall it, and change down whilst braking not when you stop.

Don't worry fella you'll get the hang of it.

First thing to practice is tethering the clutch and throttle together. When you let want to change gear, pull the clutch fully in. Press your gear lever up, and then as you slowly release the clutch, gently increase your throttle. Make sure as you add to one, you take away from the other, nice and slowly until you get the hang of it.

This'll give you something to get your teeth stuck into for now but i'm sure you'll get loads of help on CBT day! They'll take you from absolutely no experience so don't be worrying it won't be up to scratch it'll be absolutely fine!

That is why it is called basic training - it's geared to giving you enough skills to survive on the road.

Thats why you need to keep renewing it.

Most training schools are more than happy for you to use your own bike, provided you have all the relevent documentation on you and you don't ride it to/from the day without a CBT.
