Bike Not Starting

[21QUEST]

Hi Guys, hoping someone might have come across/had a similar problem. I had a 'mare of a day yesterday with the bike.


Bike starting ok initially. I had to stop to adjust mirrors and then it wouldn't start. Seemed like battery didn't have enough juice.


Tried 'bumping' it but no joy. Then got some jump leads and even trying off a car, it still wouldn't start. Starter was turning over engine but just didn't seem to want to fire up. Of course, plugs now probably a bit wet.
Eventually it started with the handlebars turned to the left hmmmm. Tried that a few times and it seemed sure enough, turning bars to left appeared to be making a connection(symptoms of intermittent connection..break in wire or connector blocks).


Anyhoos let it run a while , switched it off and wouldn't start. Funny thing(well not funny lol), it now wouldn't start even with trying to jump from another vehicle. No amount of wriggling bars/wires would make it start. Engine kicking over but just not starting. Looked like perhaps no sparks and an extremely wet plug...as you could smell the petrol.


Now the most surprising thing was, even before it got to the point where one could asumme the plugs were now fouled, it wouldn't start from a direct connection to the starter motor


At the moment, I've just had a look at the wiring diagrams and hoping it's the wire shared by both coils.....since it wouldn't even start with a direct connection to starter motor even though engine was turning over quite strongly.
In any case , got a new CDI unit, coils/HT leads and plusg to go in , if need be. I frigging hate electrical sh*t


Okay folks, you ahve the evidence and wotnot to help you come up with a solution.... .



Cheers

have you checked the main engine earth Ben ?

if you think moving the bars made a difference then it's more than likely one of the connectors at each handlebar (switch cluster for on/off on the right, clutch safety switch under the left) or one of the connectors behind the headstock under the airbox.

check the red wire, in the connector block on the left of the loom under the fairing(I'm assuming you still got faired) gives it a wiggle and see if it is loose or green!

A long shot but it is a live( I think), to starter relay,battery, main fuse, clocks, reg rec...loads of stuff!

Flymo, if it's connectors, that'd be so brilliant. I'm already having nightmares, thinking about trying to locate a break in a wire. I really hate electrics arghhh.

Guys, any thoughts on why it wouldn't start with a direct connection to starter motor?

Do you know what the connector block is for and/or colour. Might be same for naked.

*goes off to look at wiring digram*

Because powering the starter only does just that, if you have a loose connection that effectively means the ignition circuit is not powered (clutch switch/kill switch etc) then you'll spin the engine but get no spark.

ahhh don't know on a nakid, but on mine its big white thing at the end of the loom over the headlights, lots of wires in it.

Sorry I'm probably not helping
