GN250 won't start. Please help

**sam.la** · 31st October 2011, 07:26

I have come to my first crossroads with my GN250... It has been running great but when I went to start it this morning. It wouldn’t budge. I checked the killswitch and the key turn on the side, both were on.

When I have the key turned on the electrics all work ie. Lights, horn. When I press the ignition it makes the sound but nothing the motor won’t start? Is this a spark plug issue? I hold it for long periods and still nothing apart from making the starting sound. Seems kind of random because it was starting quite easily the last few days and today it just wouldn’t start...

Any help is appreciated.

Engines need 3 things to go...fuel, compression and spark.
Granted, they are all needed in the right quantities, and at the right time/s.
But it is real easy to check their existence (or not). Can you do that?

Is the stand down?

Fuel is right. Not sure how to check compression. Could possibly check the spark plug?

Yes the stand is down...

I asked a guy at work because I haven't used it in the last two days, he said it could have flooded?

Lift the stand and try again.

AND make sure bike is in neutral and clutch pulled in.

there may be fuel in tank but too low, try switching over to reserve. It may take a couple of minutes to fill the float bowl.

Make SURE the kill switch on the r/h bar is set to RUN.....

We all have done THAT at one point...

Put stand up.
Make sure the neutral light is on.
Pull the clutch is.
Set the fuel tap to reserve.
Pull the choke out.
Check battery connections are secure and clean.

Buy a large hammer if all else fails.

Have you got access to a multimeter or voltmeter?

I'm starting to think it's the battery. I'm trying to start it now and the starter motor is getting weaker and weaker...

Tried with stand up and everything.

Is it safe to jump start a bike battery with jumper leads to a car? I don't have a battery charger

Ok turns out the battery drained because I left the isolation switch on. Didn't know it would drain the battery.

Just jumped it and its going fine

.

Thanks for all the help!

arrrghhhh... spoke too early. It starts fine but it seems as though the battery is not charging?

After jumping the bike I left it for about 20-30 mins in idle with lights off, then I went to go for a ride after I turned the lights on and gave it a rev the engine just died and it wouldn’t start again. This time there was no buzzing sound what so ever. So I jump started it again, starts fine so this time I decide to leave it for an hour on idle with lights off and I go back down and gave it a rev and then it died. I tried to use the ignition but still nothing?

It seems as though it’s not charging the battery? Any suggestions to what may be going wrong?

Anyone have a battery charger I can borrow
