2004 Yamaha R6 non-running wiring loom disaster – beware!

There are lessons to be learnt here…

The lad with this R6 had a friend of a friend who looked at it and decided it needed some tweaking to the alarm. He took a load of wires out, shorted a few and in the process cooked the ECU. Oh dear. And the key and key reader with it. We tried all we could to re-wire it to get it going but the loom had been thoroughly butchered. Everywhere we saw new tape we had to pull the loom apart – in effect we took the whole back section of wiring apart and pieced it back together.

Our good friends at Webbs Yamaha in Eye lent us a few key bits so we could problem solve without spending money on parts. In the end it was obvious a new ECU would be needed. The real shame is that this one was too early for us to flash; we can do  later models no problem. So we got an American ECU from Track Electronics that was a non-key reader and fitted it – bottom line we got it finished and the bike ran perfectly, but it was a lot of labour and messing about.

We were happy with the job, as was the owner. He was fuming about letting his loom get molested in the first place though…
