Bike not starting

**HungusMaximist** · 19th July 2007, 12:29

Hi

My bike's a 91 GSX750F.

Got back from a 3 week holiday overseas and I tried to start my bike and it just the engine wouldn't start.

Battery is all good, all new. I can hear the starter motor working but the engine isn't turning over.

Petrol is old and I didn't drain it out of the carb before I left and just wondering if it could've flooded it.

Any suggestions, tips, troubleshooting....

Thanks.

Have you tried roll starting it?

**HungusMaximist** · 19th July 2007, 13:31

No, but that's gonna be hard as I live down in a steep 20 m long drive way. But I could try. Thanks.

just checking but its not something stupid like kill switch / fuel tap lever in off position is it?

Drain the carb fuel bowls. When you say it isn't " turning over", do you mean that the engine isn't running?
Turning over normally refers to crankshaft/piston movement, as opposed to idling, revving.

Kill switch is on. Fuel tap is in the on position, although there's at least 1 litre or fuel inside the tank and it's been 3 weeks or so. I maybe should drain the carbs and tank, and add fresh fuel. Anyway draining the carbs is something I need to read up on as I haven't really had to do it before.

On the other hand starter motor kicks in hardy and you can hear it trying to start the engine, but the engine doesn't start. It means the engine isn't running at all.

Any other suggestions? Troubleshoot..

tried reserve?

3 weeks wouldn't root the fuel i wouldnt think...

Connect up a jumper battery,throw i4l of BP super in the tank ,turn it to reserve .Turn her over with NO throttle.
If you still have no luck then get back to us.
--I'M sorta covering off 3 possible issues at once here

You know what, I got her going yesterday. I've realised I've been adding too much throttle while starting. I switched the choke on full and pushed in the ingnition for about a few seconds, with a few coughs the engine came alive.

No throttle was applied when I was pushing the ingnition button.

Thanks all for your help.

I'm having trouble to start my bike atm (she's pretty flooded now I would think).

I do need a new batt I'm pretty sure (I think i still have the 1988 one in there)

But I can never start my bike without giving it gas, and the choke doesn't do a thing as it justs seems to turn it off.

Cheers

Check the plugs. Check for spark. If thats all good, then give it some Engine Starter in the airbox and try start her again.

If my bike doesnt start, its pretty much always a fouled plug or something that engine start fixes. =P

I have the 93' 400 toy of the same. I pretty much always do as you said above.

Fuel tap on 'prime'
choke on full
no throttle
push ignition for a few seconds

once she's away.. knock choke back to about 1/3rd, & turn fuel tap to 'on'

Most of the time she behaves!

Enjoy & take care

from my basic female understanding of motors..

"Prime", "primes the motor" I think it allows a little bit of fuel through into the carby.. ready for the motor to fire.. something like that anyway..

(I'm sure a "bloke" can describe it better...

)

I understand it better with lawnmowers.. there is a little rubber button you have to push about 3 times.. before pulling the rip cord.. otherwise the bugger doesn't go!!!

clear as mud....???
