Starting issue

[ghostbiker]

Ok the problem is back, so realy onl went away for a day or so riding.
did it a couple of times yesterday but not for long and then today its been a real pain in the ass and 1 more added part to it.
While i was out riding i was doing around 60 and starting to line up an overtake when it just compleatly died on me. clutch in (thought it was something serious lol) and coasted to a halt. tried to start and just turned over.
ignition off and on a few times, each time trying to start and again just turning over. try it one more and it fired up with a very loud back fire (new boxers please) and ran as allways perfectly.

went to my local spanner and told him. problem is because its intermitent its a bitch to trace. i was lucky and when i tried to start it in front of him it didnt start.
He confirms as i said, there is deff no spark. turn it on and off a few times and it may or may not start. there seems to be no rhyme or reason.

Without me spending a small fourtune for him to have it in he threw two ideas my way that are mew ideas.
1 i had been thinking off ... the data tool imobaliser.... and the other is ignition pick up problem.
now he hasnt heard of one playing up on a fazer but has seen it on other bikes and it normaly shows up when the bike is warm. so it could be that.
problem is finding out just which problem it is.

Now i have a data tool imobiliser on the bike. it was on it when i got it at 3k miles and has never given any trouble. i dont know if it was factory fitted or not. the wires are hidden behind the rear panel so its hard to see but he says "some" yams have a plug and play type alarm plug, and you can buy a bridge plug from yam to unplug the data tool and plug in the bridge plug. anyone know about the data tool thing? its like a little tab fob that i touch on to the pad on the bike.

might get round to removing the rear end and looking for it to see but would save me time if someone happened to know.
