Rode the bike Friday night, 30 mile round trip, parked it up about 9pm. Saturday night 8pm goes to start it, and it just turned over without firing up.

After about 10-15mins it was as if the electric start was struggling to turn over and just kept giving up on me and the lights were also dimming while this was happening.

Got to the point eventually where if i hit the electric start, it did nothing at all, was as if the switch was redundant. Lights on the dials got dimmer, and the neutral light was dim with the lights on, but brighter with them off.

Anyway chucked a multi meter on the battery while it was on bike, [and bike switched off] and it read about 10-11V.... switched ignition on and went to hit electric start and it read about 5V. Only person I have asked with some bike knowledge insists it is simply a dead battery....

2 questions

1 - Does it sound about right to you?

2 - When i bought the battery, i put the acid into it and connected it to a charger and it showed as fully charged out of the box... so i only stuck it on charge for about 2hrs max and used it from then on. Should i have given it a much much longer charge before stickign it on bike?

A battery in service should read 12.8v (12.6v cold weather) the morning after without switching on or 6 hours after a remote charge.
What voltage have you at 4,000rpm?

I am awaiting a battery charger to be brought to me so i can give it a good charge and check it at 4000RPM. I was told that when fully charged and back on the bike, it should be reading not far off 13V just ticking over and idling, not sure if that was correct info

Doesn’t' sound like a battery problem to me.

Short version - bike doesn't start, so you crank it for 10-15 minutes, now the battery is flat. I'm surprised that battery lasted that long!

The battery will need to be charged, then find what prevented the bike starting in the first place! (Check kill switch, fuel, spark...)

Dead battery now, but it wasn't before 15 minutes of trying to start. Question is why wouldn't it start in the first place rather than why it won't start now.

Tried riding the bike to MOT Tuesday morning, and while riding noticed bike would sputter and jerk a lot.

Rode motorbike yesterday on almost empty tank, when I got home I could smell petrol so killed bike and looked at engine, noticed a dribble of petrol coming from bottom of fuel bowl.

quick review of prev posts would suggest answer to that one is owner has more ideas than spanners, and less nouse than either.

Rik? My advice; start at the top and clean the slate; get the Haynes book of chinky bikes; follow the instructions in 'Routine Maintenence' do the tappets properly; flush the tank; clean the carb; change the spark plug; put anything that isn't standard BACK to standard, charge the battery and start from a known base-line.

You are pissing in the dark, laying problem on problem, never really bottoming the root of anything and getting into a muddle of meddle.

If it cranked strongly for even a few minutes before you managed to flatten the battery, then the battery itself is fine. Recharge it and find the real problem.

Fuel. Sidestand switch. No spark.

Whatever you do, don't tell us what bike it is, that would make it too easy.

By the lack of response, I can only assume the kill switch was in the kill position!

Not just the battery, the starter as well. They are not designed to run that long. Always use the starter in short bursts, don't overheat it. Wink

By the way, let's assume OP did not forget all the buttons and taps to be in the right order. There is a possibility the starter is faulty, not engaging with the drive/crank. Thinking

OP, before you attempt another start. Take off the spark plug/s and let them dry out before you press the starter button. IF the fuel was ON, you just pump through the engine quite a lot of petrol = the spark plugs are soaking in it. A ignition will harm the ''in petrol soaked'' plug/s.
