Morning folks,
can anyone help(i cant believe im having to ask but im at a loss here)
anyway,the gpz550 race bike i run in the crmc proddie class (the black one at our trackday) has an intermitant ignition/power fault.
The battery is good and it is charging well but every now and again i loose a couple of cylinders,no spark then i get all 4 ,then nothing and she wont fire ,i have tried another igniter,pick ups and coils.Ehhh,yup thats what i thought,now i have linked out the side stand switch and the starter cut out switch (clutch lever) but and here is the problem,would the safety diode box mess up the ignition in some way where i have bridged the clutch cut off,its the only thing i can think of
the colours on the lock out switch are yellow green(goes to diode box)black /yellow (earth) and light green(which goes to neutral light and diode box).
the bike will still only start in neutral but you dont have to pull in the clutch and it has been fine wired like this for ages and ran fine getting two seconds and a third in class with Chris from practical sportsbikes on board
my brain hurts

normally when you bypass the clutch + side stand switch the bike will start in any gear that is the purpose of the side stand switch + clutch switch to prevent the bike starting in gear + cutting the ignition with the stand down. sounds like you have not bypassed the switches correctly

Every bike I've disconnected the "safety cutout" switches all I did was a wire chop (or link) with no probs..... that includes Zeds, GSXR's XR's, XT's... etc.

If the problem is intermittent, then I'd check your by-pass link and make sure its good - best to solder the wires

If still playing up - which pair of cylinders is the fault ? If # 1 & 4 - or - #2 & 3 then its coil related - either a coil breaking down or power to the coil

Are you running NGK plug caps
Try binning them and fitting caps without in-built resistors as they often get overlooked as the resistors die
