Lets hope that was the problem, it sure sounds like you found a resistance problem.

Current symptoms are when starting from cold it takes a few seconds before it catches. If left to idle on it's own it will stall, then take a few attempts before it will start again. If you blip the throttle it almost stalls then slowly the revs pick up.

Appears ok when warm except for the fact that it now surges between 55 and 65 mph, sometimes quite badly, similar to pulling the clutch in then letting it out non too gently!

ECU bad?

Take it to a dealer ,sounds like tps or faulty ecu ,otherwise subscibe here and you will have access to "ask Kev" he will help ,but as captmoto has previously stated that it is unfair to those who subscribe if Kev helps out on the general forum

I havent subscibed myself this year ,but will be doing so very soon as there are other benefits including the manual download which is VERY VERY helpfull and that would cost you more than a subsciption normally

Good luck and hope you get it sorted soon

Dont forget if your in swansea give us a shout

Latest update. Having eventually got the bike to start this morning it cut out then restarted whilst taking the bike to the dealers. This wouldn't have been too bad except that I was going around a corner at the time. End result was that it highsided me out of the seat and with my feet off the pegs in true superman style I crossed the on coming lane of traffic. Fortunately lady in Mondeo was quick enough to stop and I managed to gain control and stop after mounting the kerb.

Surfice to say I wasn't that impressed!

Amusingly (it is now) the RAC (or Yamaha Assist) insisted that they would not take the bike straight to Fowlers but instead they would attempt to fix the issue. The patrol man who arrived was soon under no illusion that the he was taking the bike straight to Fowlers. Having taken me back to the house I followed on my DR.

Fowlers apparently have no record of my bike, nor the two services they have performed, nor the fact that they sold it to me less than eight months ago. As if on que the Yamaha sales person walked past and cheerfully asked how the bike was going. Quite possibly the biggest mistake he's ever made. :-)

Having rebooked the bike for Fri, the icing on the cake was the technician who on presenting me with the sign in form stated "I couldn't check it in properly because it doesn't start".

And breathe...

sounds like these people are really pissing you about.

I know its easy to say as its not happening to me, but i would say have your bike, when you can fix it i'll have it back, but for now its not working sort it.

and leave it at that.

Ive read of a few people that yamaha basically didnt want to know until they just left there bike there and said its not working sort it!! and then the dealer had a problem so had to fix it.

Technician from the dealer got back to me today, as they didn't get to look at it on Friday.

They're replacing the clocks and entire wiring harness under warranty as they're badly corroded internally. Water ingress into the back of the clocks via the connector, the right hand switch block (hence issues starting), wiring harness connectors at left of fuel tank and relays.

Bikes never been pressure washed by myself but I do use it Mon to Fri every week for the last eight months.

At least I have way forward. :-)

Good job your getting it changed under warrenty.

My bike was out of warrenty when the kill switch cable corroded through on the left side set of electric blocks. I got it fixed at my own cost but the other connects etc arent the best and at this moment i cant seem to find heat shrink to place on the cables big enough so i dont have to cut the connectors off.

For others i made up a piece of rubber with a few cable ties to hopefully help stop the wetter getting into the cables. It just sits in front of the tank where the front goes in and is only loosely placed in so as when the bar moves in and out it doesnt restrict it. Will post a piccy laters.

17 months now second hand xt660r '04 13.000 from me and 10.000 from the previous owner no trouble at all !

Lets hope this will fix it & you can enjoy a trouble free bike.

Hello Maxwell123455.

Try Silicone Rescue tape, when you put it under tension it melts into itself forming a watertight seal. No need to remove the connectors... Hope this helps?

Bike still with the dealer, I'm starting to think they're making the harness themselves... ;-)
