Ok so went to start the bike lastnight and it just turns over and wont fire, i had fired it up 10 minuits prior to this and it fired up first time wich puts doubts in my mind that its gunna be fowled plugs but havnt checked yet i shall be doing that first thing in the moarning.

But when i hit the ignition switch the bike turns over but doesnt fire up and the digi clock on the F4 speedo goes out which in my mind means something that converts the power has gone as it must be draining power from the speedo trying to fire the plugs which leads me to think i need a new ignition control module or coils.

Yes i've checked the Fuses.

So the question are once ive checked the plugs could i fit the F4 coils onto the f3 to see if its that or am i gunna do more dammage?

 

is it backfiring or anything? have you checked for spark? I would do that first personally

 

+1,
sounds like your gonna have to dissect the bike
