Choke problem?

[Grant1Shepherd]

Hey guys

Went on a ride today across London, took about an hour, got to where I was going and parked up, the bike was parked for about an hour and a half to 2 hours, when I got back to it I started it and it was sounding like it was too cold to stay on, so I put the choke on a little bit and the bike stalled instantly.

I turned the choke off and turned the bike back on and then it really didn't sound happy, sounded like it was struggling to get fuel in it, when I Rev'd it a little it was just wasn't the normal noise, I rode it back home to which after about 10 minute and the bike getting warm it sounded perfect, and it did the whole hour long journey fine, even when I came to a red light it sounded perfect despite what it sounded like before I set off.

I'm not ruling out the possibility that I did something wrong and am an idiot so please don't hesitate to stay I made a mistake because I need to know so that I don't do it again.

Hope someone can help me out with this.

Thanks guys

These bikes need very little choke even in winter, when you when back to it, it certainly should not of needed any choke.
Maybe a jolly good thrashing somewhere is all it needs - get that london muck out of its lungs.

Speaking of which - how is the air filter.
Also a while ago I was starting to get starting problems and a new set of plugs was all it needed.

That's what I was thinking, I'm thinking I might of just tried to confuse the bike by trying to give it more fuel, the air filter has been recently changed as well as all the carburetors have just been cleaned and balanced.

Did you buy a low budget air filter?

I get a similar thing happen to mine every now and then. I've found that if I have to put a little choke on while the engine is running I have to give the throttle a little blip otherwise it stalls (I think it's because it can't handle the sudden extra fuel intake and just gets strangled, so a little blip pushes it through) if I put the choke on before starting up then it has no issues. When it starts sounding abnormal from this issue, I do like fazersharp stated and give it a good thrashing and so far that has sorted it.

If you feel that the bike will need choke, ie: very cold mornings, then you should put the choke on first then start the bike and adjust the choke so that it's at a reasonable tickover level.
Turning the choke on after it's started will just make the bike run like shit, as you've found out.
Put the choke on about 25% if you need to use it.
You shouldn't need it at all in this weather we have right now though.

Putting the choke on a smidge (when needed) before starting the bike is what I do 99.9% of the time but there are those rare occasions when you're in a hurry and you just don't think and try to use the choke when the engine is running, and giving the throttle a little blip seems to correct it.

The time I have to set out in the morning's for work it's chuffing freezing at the moment plus my garage seems to really hold the cold in, it's like a bloody freezer

Thanks for all the help so far guys really do appreciate it, just to confirm though my bike should be ok? It was fine literally after 5 minutes I got going from this problem, and it was great the whole hour ride home, I'm just so worried
