Hi I have a 2004 Aprilia Falco and it wont start. It turns over ok, it is getting fuel because if you open the thottle a little the engine cranking speed decreases, but no spark, (I think). I have put a strobe probe against one of the high tension leads as I turned the motor over and it doesnt illuminate. It has an after market Meta System M3757T V2 motor cycle alarm and engine immobiliser fitted which appears to be operating ok, (but I'm not 100% sure). I have checked all the fuses, but have not physically removed the plugs, as this involves pulling a lot of stuff off. The plugs were checked, cleaned and gapped only about 1000kms ago, and the bike has only done 7000kms. Any advise or things to check would be greatly appreciated. Regards Craig

The two wires you refer to are, (I presume) the ones coming out of the computer under the seat behind the battery. There were no error warnings or codes on the instrument LCD display when I turned the ignition on before connecting these wires nor were there any after I connected them and turned on the ignition. I can definitly confirm that there is no spark to the plugs as I have strobed all 4 HT leads, (the engine has 2 spark plugs per cylinder) and there are no voltage pulses to any of them. Each cylinder has a seperate coil pack so whatever is causing the no spark situation is somewhere before the coils. Regards Craig.
