Gen 1 ECU for sale. Not flashed original stock unit. It came out of my 2012 Tenere in complete running order. The part number is 23P-8591A-30. I believe it was used in the 2012 only. $250. Yamaha has superseded this unit to 23P-8591A-70.
Ramseybella as you most likely know I have had all the same problems you and others have had. I have been giving updates from time to time on my bike after the replacement of the wiring harness. I now have 6,600 miles since the wiring harness replacement. The bike has been perfect. It starts...
Just an update since my last post. I now have a little over 2500 miles since Yamaha replaced my wiring harness. The bike has been perfect. Absolutely no issues. I will echo 911guy and say I am very happy to be able to ride it without worry.
Just the main wiring harness was replaced. The sub harnesses are original to the bike. According to the rep, the harnesses are sent to Japan to be evaluated. He said the engineers cannot find anything wrong with them. I have not spoken to the rep lately to see if he has any information about...
Here is an update on my bike since Yamaha replaced the wiring harness. I got the bike back on 5-18-17. I have done approximately 1500 miles with numerous starts. The bike has been perfect. Starts strongly every time with no stalling or high idle. I have only had a few posts here because I...
Re: Head count: Dead or High Idle issues only Who has been bit?
I posted a story quite a while ago about my no start, high idle, throttle locking and engine dying. I suggested separating the wires in front of the throttle bodies. Well that worked for a while but the symptoms came back. The...
You might want to read my post if you have not already. It is in the same section of power and exhaust and is titled "hard starting and other problems". Perhaps it will help. I used to suffer from the same problems you have. I have been trouble free for months and over 4000 miles.
I did not post on the forum to prove anyone wrong. I know very little about electrical theory. Perhaps I am using the wrong terminology, lets just call it interference. I have worked on many motorcycles and cars over the past 50 years. This I do know - when I put my finger on the harness and...
Bigbore I am glad you are going to give it a try. I put the foil on for two reasons. One was to make it much easier to see in the photos. The other was an additional shield. The foil probably does not help that much without being grounded. I figured it did not hurt to leave it on and if I...
Ferret, if you need any further information or pictures just PM me. I can work up perhaps a more detailed explanation of what I did. So far I have had no problems for 3100 miles. Best of luck.
Ferret your hard start issue could be directly related to the mechanics work. I would bet that he certainly moved that wiring harness some to perform the spark plug change. I and others have seen direct results from moving the wiring harness in front of the throttle bodies. If your problems...
Re: Idle speed problem min 800 max 3500
For all the gentleman who have been following this topic, please see my post under Tech discussion - power and exhaust. I had the same discovery as Fintenere that he posted on 1-5-2013. As I read through all the posts I saw someone mention EMI as a...
Re: Head count: Dead or High Idle issues only Who has bin bit?
Ramseybella you already know that I have had the dead and high idle problems. I just thought I would add my bike to the list. Incidentally I have logged 2,923 miles since I posted my fix. No problems whatsoever. Good starts, no...
