So I've narrowed down my FI light problem. I get a c27 code (ignition 4) from time to time and the bike runs like crap. Today I checked the ecu connections started the bike all was fine touched the ecu connection down and FI light, revs dropped and idled like crap. Lifted the connector slightly and back to normal(revs back to 1.4k, sounded normal).
Does anyone know how I could fix this problem. I've narrowed it down to 3 pins directly connected to cylinder 4 but they all look fine.
Could I just buy a new connector or bring it to the dealer or indy shop?
I know that Pro 6 Cycle has dealt with a similar problem on a friend's track bike - he gave up trying to fix it himself, and took the bike there, and it's fixed now.
The problem is that the harness connector is part of the main wiring harness, and the individual bits inside that harness connector aren't available separately, so the only "official" way to fix it is to buy a new wiring harness and re-wire the bike ... There are "unofficial" ways of fixing it but you have to be REALLY careful, those little bits are fragile.
