Been working on a mates Z1r,bike would stop firing on no2 pot, so fitted new coils ,new Dyna s,new leads,Nippon Denso plugs,new plug caps,Still stopped firing on N02 pot,swapped leads 2 and 3 now stopped firing on no3 and n02 fires ok good 12volts at coils(wired George mod)..Any thoughts?

Compression test Paul.

Ted

All good Ted,shims checked,timing all good..

Paul,

It must be either the lead, plug cap or output post on the coil....

It is obviously an ignition component failure.

The problem has been swapped over to #3
That means EVERYTHING with #2 is good.

My thoughts exactly guys, but all new components and the fault is exactly the same,new leads, plugs .dyna,caps,might try swapping coil and leads for 1 and 4 with coil for 2 and 3?

Well if you done all that Paul it can only be Fookin woodworm try Ronseal.

Would Wickes own make do the job Ted?

forgive me big lad...but did you swap the leads in the out puts as well or just the lead cos if its following the lead take one of the myriad of other bikes you have and try that

Maybe when you are in under the tank you are disturbing something??

If it was a coil issue BOTH 2+3 would be down.

Swapping it would mean 1+4 being down.

The HT lead in question isn't arcing out.

Try running it in the garage with the lights out.

Keith brand new coils with sealed in leads,new caps,plugs,swapped 2 and 3 over at plug cap end and fault transferred from 2 to 3.But works when you first fire her up just fails after a while?

Jim tank is off,no arcing.

Was same fault b4 we replaced all the ignition components!

One thing i have noticed is that the lead that goes to the pot that fails ,either 2 or 3 shows intermittent firing when you put the clamp from the strobe light across the ht lead

Paul, sounds like that new lead is breaking down ??

Weird that because that was what the old lead and coil were doing with the strobe?

even new parts can be faulty don't presume because its new it is without faults
