Got a bit of a panic on,two friends have called in on the way from the I.O.M. should have got on the ferry to Bilbao tonight,have missed due the one of their bikes(America) braking down,as soon as the bike gets warm,motor just miss fires and won't pull,plugs are white,looks like all the symptons pf the CDI gone AWOL,is this common,will have to get it to the dealers ASAP tommorow.

Any other ideas??

Quick charge test. set voltmeter to the 20 volt scale and connect it across battery terminals,with the engine running at around 2000 RPM measure battery voltage at the battery; battery voltage should be 14.5 volts/+ or - 0.5 volts .....above 15 volts faulty rectifier/regulator but first check the battery terminals are clean and tight,check frame and engine earth connections are clean and tight...battery fully charged,check that any fuse in the circuit is not blown or of the correct rating..(fuse#2ignition switch main feed )[30A]..(fuse#5 instruments , ignitor unit,starter relay)[15A]..(Main fuse #11)[30A].If it's below 14 volts two more series of tests will be needed then it could be the rectifier /regulator or the alternator if this is the problem. That will check those. As far as the Electronic Ignition:It's not the transistor type which uses the battery. Ours is the Digital electronic type CDI (Most of which do not require a battery. Uses a microcomputer to calculate perfect ignition timing. Most of these systems incorporate some kind of fail safe mechanism that kills the engine when timing ,engine speed,or fuel delivery goes off scale.If things are a little off the computer advances or retards the timing to suit the engine requirements.......... System Description: a)Pick-up coil...b)throttle position sensor...c)Igniter unit....d)Ignition HT coil. a) As each projection passes the coil a signal of low electricity is sent to the c)igniter unit [brain] evaluates the signals from a) pick-up coil which tells it engine speed,piston position,b)TPS sensor,which informs it of throttle valve position.From these signals the c) ignitor unit calculates the correct ignition timing ,and supplies the proper voltage to the d)HT coil . The basis for the calculations come from the pre-programmed ignition parameters within the igniter unit.[Brain] d)Ignition HT coil (Black box) is a low resistance primary winding is fitted to allow amore rapid coil action;this allows the coil to function at low and high engine speeds superbly.It functions on the 'wasted-spark' principle both plugs being fired twice for each engine cycle once on the compression stroke{ignition coil#1} and once on the exhaust stroke.{ignition coil#2}Good Luck. Fair well.

That pretty much covers it :gpst:

Thanks for the imput,it turns out,one of the coils was arcing onto the frame!!

Also the top of the airfilter box was broken,and the was a pint of water inside,it was the second one they'd seen like that.

Good. Cheap fix. :-D
