If it cranks but wont start could be a battery problem, my Bandit did the same thing, put the battery on a tester and was only showing 50 cold crank amps.. chucked a new battery in and that fixed it....... Next problem was charging haha it wouldnt start if left for a while. Problem was the magnets on the flywheel (which are essentially the charging system) had all broken and fallen off and shit so it wouldnt charge the battery.. A new flywheel and $450 later and shes sweet.. So you best be hoping its not your flywheel!!
One way to tell is it will run rough and vibrate a lot as the flywheel is unbalanced due to being unevenly weighted by broken magnets

My GSF250 doesn't like to start before 10am. Not even kidding.
After 10 it starts first time! Well, when its not freezing.

Thing with these bikes i've been told is you start it with no throttle (and a tiiny bit of choke if its really cold), then when it catches you rev it and let it settle. Holding open the throttle often floods it.

Check the battery first as its easier than taking bits off and flushing them

haha thanks all mechanic said the choke seized whateva that means... pickin it up tomorrow will give yas an update when i find out what exactly went wrong or caused it. thanks again... much appreciated

Ok, I'm gonna bump this thread as today I have this problem with my bandit. I've only had the bike since wednesday. Have only rode it on wednesday but have started almost all days in between at the request of mates coming to have a look.

The Fuel is on with a full tank. The battery seems to be charged as all lights are on and the starter motor cranks strong. When I went out to start it, its started fine but died a few seconds later and wouldnt crank over.

Ive tried holding the throttle open and also with a little choke. I've tried it with the reserve. I haven't yet tried to roll start as I'm not hugely confident at doing that yet.
Is there anything else I should do before going any further?

My driveway is also quite steep, so on the off chance I do try to roll it and it doesnt work, I dont really want to be stuck at the bottem.

[GSF_Lou]

Right, so in the space of writing that post and going out to give it another go. Its back to the start where it fires over but just dies.

Should also mention that the gas is Gull Force 10 and its been in the garage since I bought it, and stored inside the showroom at the dealers.

[GSF_Lou]

Ok so after all that, I left it another 10 minutes and then tried it with full choke.
It fired over and came right, and now starts first time. So I think we can just put this experience down to me being a f'n noob and leave it at that

One further question however, my choke needs to be held on full (or anywhere in between) or it will return to closed. shouldnt it stay put until i close it?

Think these bikes are a bit 'individualistic' when it comes to starting habits - every one needs a different start up sequence. It'll take a little while to work out the sure-fire way of starting yours, but once you get it, it's kind of like a second layer security system! (Yeah, sure, you can take my bike for a 'test ride'. You just have to start it first).

I know my partner's one is a bitch to get started on a cold morning, but generally the start up goes:

Attempt starting no choke no throttle.
Attempt starting Full Choke, no throttle.
Attempt starting no choke, bit of throttle.
Attempt starting full choke and full throttle.
Go and wake 3L4NS1R up and get him to bump start it for me.

usually it doesn't get past attempt #2, and very rarely past 4/5.

Good luck!

[GSF_Lou]

Ok thanks for that. I think what threw me off was the ease of which its started every other time. I'll make sure I remember that sequence and run through that before I freak out too much.

[The Everlasting]

Good that you managed to sort it out.

I have found that during cold winter mornings,it really is hard to start,but summer it's easy.

[Hopeful Bastard]

Yup.. These things are a bitch.

Make sure you have good plugs. If not, Replace them with some decent quality ones.

Next, Make sure you have good fuel in it. Mine hates stale crap.

Then, tick it over. If it doesnt fire, Throw it onto some jumper leads connected to a good battery to see if it ticks over faster.

Starts but then dies, Check your Idle. Adjust if necessary. I found that if you get it to fire and then it dies, you are screwed!! until it drains all the gas outta the carbs with a bit of help..

Also, Check your float levels. Mine is running too rich at the moment even with the choke off and the idle set for summer..

[mittens]

If you scrap the bike will you sell me the wiring loom?

I've got a GSF 250 and it's the last part I need to make it run...

Check your float levels. Mine is running too rich at the moment even with the choke off and the idle set for summer..

Don't suppose you know what the floats need to be set to? I've got a GJ74A and am just in the process of overhauling the carbs as it happens. Problem is both the GSF400 manual and the GSX250F manual have different carbs to the GSF250 (no manual as you probably know). I have attached a parts diagram of the carbs.
