Hi smokeyfish,
Thanks for reply.
Yes, we did check for spark and found nothing - well certainly not conclusive (read on). Funnily enough as a very kind gentleman (passer by and fellow biker) was helping (or mainly leading tbf) the repair effort (at side of the road) this was one of his checks.
On turning the bike over (whilst earthing the plug) the bike suddenly sprang to life (running on 3 cylinders). We had just prior to this fiddled with the female port of both connector blocks in an attempt to tighten up connections of ecu.
So anyway going back, with the bike firing, whilst earthing the taken out plug (even though we were looking for spark) we sort of didn't see a spark if that makes sense? The bike however did run. I quicky hit the kill switch - not sure why tbh, and we both started to put the bike back together thinking perhaps that it was now cured (after fiddling with connections of ecu).
I continued my journey with my new found friend for a few miles until An Sibin (at foot of Healy pass) where we stopped for a celebration coffee only to find on return the bike fired fine but cut out almost instantly.
Tbh it's been a nightmare from start to finish - the bike is still in Ireland and I've landed back in Wales early this afternoon.
What is the loom port fix please smokey?
When I get the bike recovered back home I'll look in that direction for sure as I'm positive it's something really simple but unpinpointable if that makes sense?
Kind regards Jonathan
