2001 CG125W - Bike dies on full choke?

Now, this hasn't worried me until recently (Because I never use the choke to start my bike) but...

When I put the choke on half, the revs don't increase (I have no tacho to prove this, but the engine sounds exactly the same with it on, and off) and it doesn't really do anything to help or retard starting the bike.

This, I don't understand at all, surely more fuel should be getting into the engine, so should therefore be revving a tad faster...

When I put the choke on full, the bike just totally dies. It will not start at all. I've tried this with the bike warmed up, without the bike warmed up, tried flicking it on while the bike is running, and in every instance this totally kills it.

Now this and my first point don't go hand in hand, if the choke lever was broken then there would be no effect at all putting the choke to full, but this would explain why it isn't working on half.

The only thing I can think of, is that my mixture is a tad rich, but this would probaby rear its head in my first case too.

I'm hesitant to adjust my mixture, as I don't think I have the experience to lean up my mixture. Sure, if I was richening it I'd have a go.

Am I on the right track?

White plug = lean mixture, not rich Wink

If it helps, by my NSR speedo and his own speedo, my mate used to hit around 75 downhill on his P reg CG. Then he wrote it off and got a courtsey one on a 55 plate which was lucky to hit 65..

Yeh it was old style. I'll see if he'll part with the carb if you want, because he's got it in bits ATM.

Yeh lean's bad, on a 2t it can cause siezures and hole pistons. Not sure of the consequences of it on a 4t.

Ok,

Thanks.

The plug actually has white ash on the electrode, so I know it's not rich now.

Mine did the same Toby R.
I forgot, as it's been in pieces for over a month after somebody knicked it. just got it started for the first time, after a long while trying, got it started after i remembered not to put the choke on full.

Yeah, my CG is exactly the same. Nothing to worry about.

On a cold day:
I normally kick the bike over with full choke on just to get it running, and keep the revs up a little just to start the warming process.

Then i change to middle and leave it for a couple of minutes to fully warm up.

And finally i switch the choke off and ride away......into the sunset... Laughing

Thats what it should be like, unless its flooding the engine by continously trying to start it at first!!

then adding more choke your flooding it even more and dies.

ah, excellent Smile

that means bike is up and running, just waiting for the insurance company to send me back my V5 and keys so I can put petrol in the tank. They seem to be taking their time, well over a month now, I may just get a new V5 and ask Honda for replacement keys if they'll do them. just means i'll not have my service book anymore Sad

not that anything was in it.

Had my CG for 2 years and mine was like this from day 1. As long as the choke was off the bike was fine, so i just left it off.

If it ain't broke....

I chose the CG because it's cheap to run and nobody would want to nick it.

Well, I got the first bit right Rolling Eyes
