Last week I persuaded the dealer that sold me the bike to take it back and fix it (In Portugal they have to give you a 2 year warranty on 2nd hand sales).

They are specialists in marine engines, mainly jet skis so they took a new reg connector from an old Yamaha jet ski harness which was a perfect fit, cut the old one away, fitted the replacement, sealed it up with some silicon spray they use to waterproof marine electrics and brought the bike back to me last night.

Happy as Larry I set off to work on it this morning thinking all was well - not so; on changing up and revving away from second into 3rd both red and orange warning lights came on, the engine cut out and stalled for a few seconds then lights went out and engine caught again. It did same from 3rd to 4th and 4th to 5th. Had it happened on a corner I'd be either dead or at least in hospital as there's no warning as the back wheel almost locks out before it picks up again.

Underwear now changed, bike is back in garage awaiting dealer to collect and rectify.

In the meantime I thought I would post this to see if any of you can offer any diagnosis/help that I can pass on the the mechanic before he fiddles again. Could it have anything to do with the possibility that he may have wired the connector up arse about tit?
