With the bike idling at indicated 1000 revs it seems that about 1 in 50
it fires too soon almost or stalling the motor.
Thanks Cliff. The bike hasn't even seen a laptop in well over a year, it runs so well with the RazMap apart from the sneeze.
I borrowed a timing light and found in fact that it looses the RH spark at every now and then at idle (no flash of light) and stalls.
Other than that the teeth on the ring gear stay rock steady so it can't be the chain causing it. Adding a ground to the coils seemed to cure it for a while but I must have disturbed a bad connection because it started occurring again a couple of days later.
Other than that bike pulls like a train although every couple of hours it may skip a beat as I accelerate.
As I said several times, it occurs with the stock ECU also.
I will re-visit the wiring and swap the coils over see what that does.
I will try changing the cells for braking as you suggest.
Cheers
Roy
