Poor starting.
It would turn the motor over once or twice then give up.Even with an Optimate connected the starting was poor.When the ignition was first turned on the battery voltage was around 12.2v.
Once the bike had started,the voltage leaped up to around 14v.Battery just would'nt hold its charge.
New battery cured it.

Yeah my display shows 12.3v and ive had the optimate on. All i get it switch on the fuel pump wurrrrs, presss start, it turns once a bit of a cough and the starter stops. switch off do it again. still seems to show 12.3v or so.......
I tried connecting a voltmeter to the battery, when i press the starter it drops to 11.4v.............

If it is the battery, thatll be my 4th!!!
Am i doing summat wrong with my optimate?

[KeefyB]

I'm just not impressed by those Optimates.
They just dont seem to put enough charge into a sealed battery.Also have you ever seen them 'monitor' a battery?
How come the thing says the battery is good,...switch it off and back on again,...and it starts charging!
Whats that all about?
Not impressed!

Sorry andy thets not enough to start your bike you should be looking for about 12.75 volts and high 13 volts after a good run or after a charge

Where did you get that from? Is that written anywhere?

[KeefyB]

Dunno where it was,but I have heard/read that too.
You need at least 12.5v to power the fuel injection and turn the starter motor.

[andyb]

Oh well, im gunna look to get that ytz7s if i can.if that works as im using the bike only on the track these days. Ill get the original sorted on warranty....again!

[andyb]

moment of inspiration with this as my battery is ok, what about the imobiliser and resetting the engine code............it was a thread by skidlids that i found..ooh i did notice the small red light flashing although i dont have any error codes...........i think.
so who can confirm the routine for checking error codes and the proceedure with the throttle and the imobiliser........

[bolds]

you will only get error codes when the orange engine management light is on....is it?

[andyb]

No Orange light........but flashing small red one.......
