Have just found a thread on thumpertalk about the same issue where they replaced the relay for the red fan and that was the problem. I must admit lve never seen or noticed my tax fan come on. So that is my next step to replace the relay, or firstly as you said check the relay then clean or replace and use the grease as well, fingers crossed.
Cheers

OP: Could be a short from the live feed from your battery to the positive side of your run relay. Unlatch the relay bases, wash it all out and get the compressor and blow the whole setup dry.

If it was my bike I'd pull the entire loom out, wash it, inspect it thoroughly, dry it off and re-install. 70 degree Betgs were notorious for loom chafes, WR routing isn't that flash either.

Thanks Nutty, it's been happening for a while so I'd just disconnect the battery wait a week then reconnect and all good. The reason I'm thinking faulty relay is because my radiator fan has never actually come in since I've had the bike.

I've got one here atm its got an intermittent fuel pump. Its tied in with the main relay part no7 on the wiring diagram. The manual is very confusing with this, the pump is turned on and off by the ECU not via a relay. I think the main relay has the issue this tells the ecu the bike is running I'm unsure of the logic any further as yet will post up when I find it. The main relay is not listed in the fuel pump diagnostic which I find strange if you bridge this relay the pump runs.
Just waiting on a few bits and I will post up what I find.

Traced the harness it was all ok no green death that is common on these I assume because of the wheel bearing grease I used to pack the relay plugs with from new. My issue was the Main relay only its intermittent causing the bike to cut out, funny there was one at a race last weekend same issue his main relay turned its self on and off we removed it and it was all good unfortunately his harness was very very sad. Easy fix for me which is nice for a change and cheap.

ok similar problem 250 18 model rear tail light just keeps coming on clicks off then immediately clicks on traced it to the starter relay I"m hoping (relay that holds 2 fuses ) straight from the battery . put a ohm meter across the 2 terminals seems to be constantly open anyway a new one is around the $20 dollar mark going off e bay Yamaha would be a lot dearer I presume ?? so worth a try. post up if it works ..

Went riding on the weekend, came homw washed the bike-so far all good.
Put the new BnB cover on and so far so good. I also covered the start button with some electrical tape, which I wont do next wash and see what happens, unfortunately can be a process of elimination. Also got some dielectric grease but havent had time to use.
