" Get a price on this part number 90891-30032 same ECU as 01 & half the price."

Where can I get it from?

Give that part number to a Yamaha dealer, the part number is a warranty replacement ECU at half the price of a retail one, the dealer can order one in for you.

Thak you very much, Kev. I hope Yamaha in Greece agrees. I will ask them at once.

Dear Kev,

Yamaha in Greece (Motodynamics it�s called) answered to my local dealer, �this part number 90891-30032 was a replacement code and it does not exist any more. We do not have it� (my translation)

That�s what my dealer told me on October 9th, 2014, when I asked him to order this spare part for me. Earlier, on October 2nd, 6th and 8th, I had sent 4 e-mails to Motodynamics� site, but nobody answered to me. Nice policy so far.

Searching for spare parts in their site ( http://www.yamaha-motor.eu/gr/servic...gue/index.aspx) , I entered my bike�s frame serial number VG5DM011000007149 and I discovered that 5VK-8591A-01 is the one and only spare part for my ECU. (which is 5VK-8591A-00)

So, I had two solutions. Either to try to get this ECU abroad, or find it �as a used part- in Greece. I did the 2nd and soon it will be on the bike. I also bought the central switch, the fuel tank cap, the seat lock and all the three keys, red and 2 black. I paid 300 Euros, so I hope it works. I will keep you posted.

Of course I�m disappointed from Motodynamics� response (non response) to my e-mails, mainly because I wrote to them in a very polite way without asking anything for free. I just needed to be informed by them, since their experience in XTs� troubleshooting must be great. Pity.

If I ever think of another bike in the future, new or used, it wouldn�t be a Yamaha. And before I buy anything, next time, I will have a good look to the forums.

Thank you Kev, Pleiades and all other guys for your help

I have just changed the A-00 ECU with a A-01 and (so far) I see a great improvement in bike's behavior. No cutings out, smoother acceleration and decelaration. Thank you all for the information and help.

Good news mate.

I paid for my 01 ECU on my 2004 XTX to sort the problem even though the bike was under warranty, I then bought another 01 ECU & complete wiring loom & fitted it to my 2007 XTX so I could remove the O2 sensor as I had problems tunning my bike bore kit & high lift cam.

2 years later I worked out how to over ride the O2 sensor completely & turn off the O2 closed loop circuit, one year later I started building O2 controller as a plug & play mod & so the story goes on.
