Hello all.
Firstly, thanks to everyone, for all the suggestions regarding my bike woes.
I collected a 2nd hand loom, ECU, complete with coils and relays for £150 yesterday.
Tried the ecu, still no good
Tried the coils, ecu, no good
Tried a relay near the starter solinoid (4 pin), no good
Swapped the small injector plugs harness, SUCCESS the bike fired up and ran fine, not 100% but on all cylinders and idled relatively smoothly and considering it had been running on only 2 cylinders for the last 4 months approx, i was more than happy.
Now, this is where it gets weird because i decided to backtrack and issolate what the problem was and what would set it back to running on 3&4 again, i fitted all my original parts (ecu, coils, injector harness, relay) and it ran fine.
I then decided to fit a set of plugs that id been alternating between but not tried during the swap outs and NOTHING, bike wouldnt even run, it tried to fire but nothing more than that.
Both sets of plugs id been using, id bought new but had been fouled by the bad running of the engine, i know how sensitive to plugs busas are but i couldnt believe that they could cause this.
The bike is lacking power and i think the other plugs are breaking down, ive ordered another set but its rnning wich is the main thing.
Im wondering if the bad running of the engine couldve given a bad signal back to the ecu, wich had thrown out the settings in my ecu, by fitting items that were ok, it re-synced something but im just guessing tbh the bike had been getting progressively worse, even swapping between the 2 sets of plugs, so im a little baffled and sorry that i cant report a knackered ecu or loom but ive learnt a hell ov a lot, wich is invaluable and thanks to Sixpack for the link for converting to a gen 2 ecu
