EFI is flashing

#1 Post by ReggieGasket » Tue Nov 15, 2011 6:57 pm

Is this serious? I think it may have been the damp weather as the bike was stood outside under a cover. Bike is running, but starts when you turn the key - bit odd :smt012

I think EFI flashing through damp weather may be related to the sensor that lives in the right air duct just behind the screen, it has a green top if i remember correctly. I think it's known for them to throw up EFI when damp. Mine does it now and again if iv'e washed her and gone for a run, it never bothers me as i know what it is, it usually goes once dried out.

As for starting off the key..? Do you mean without pressing the button if so that is strange. Could it be a bit of corrosion in the starter switch gear button :smt017 If it's turning over when you turn the key does it keep turning over?

I hope iv'e not misread this somehow and got the wrong end of the stick.
if so i'll go and stand in the silly corner with a pionted hat on

Hey thats my corner when squid lets me have it :smt002

I see this occasionally too and follow the same path of ignoring it :smt003 It happens infrequently but usually in the damp or after a saoking with soapy water

Ahem ..... the Workshop Manual is a great source of information ...... :smt002

This info and what to actually do to test components / fix problems can be found on page 6-10 and subsequent pages of the workshop manual .... downloadable (as always) from Martin Poll's excellent website (but I don't need to mention that again, do I?)

or you could just ignore it and turn the radio up :smt002 works for me not reappered for quite a while since I stopped throwing soapy water at it

oh and if wanrt the manual I can email it to you or some other stuff that I have collected

Mine does it when she gets a thorough soaking - like 8 hours continuous riding in monsoon conditions. Its the air temp sensor that gets damp and some resort to a dose of silicon grease on the terminals

If it's starting when you turn the key, but without pressing the start button, you've probably got a short in the wiring to the start button and the starter will be running all the time, even when the engine is running.

This isn't a huge problem as the motor side of the sprag will be turning fater than the starter side of the sprag is and the way the sprag clutch works will allow that to happen, a bit like the freewheel mechanism in the rear hub of a push bike.

I'd be concerned about the starter running for prolonged periods though, it's not designed to do that and could bugger it up.

Shouldn't be too hard to track down the problem and fix it though, AF1 has a good interactive wiring diagram you can download to help.

Just occured to me that it could be the solenoid that's locked closed.

I'd be checking by disconnecting the thin wire connector at the starter solenoid then turn the bike on. If it starts then it's likely that the solenoid has locked, although there may be other safety circuits that will prevent a start.

Another check would be to use a test light and connect it to the + battery and to the red/white wire at the solenoid connector, it shouldn't light unless you press the starter button, this should work with the key off, but I'll check and get back to you if it's anything different than I've described.
