At the end of this:
Can we get a part number and vendor for a hand held tool that will connect. It appears the black tool that says "yamaha" in red works?
How about the special connector cable that will plug into the tool mention above and to the WR's comp ECU connector?
Please vendors and part numbers. This information is really solving peoples problems. Thank you al
I got the YAMAHA FUEL INJECTION DIAGNOSTIC TOOL part # 908900318200 from Ebay (http://www.ebay.com/...984.m1497.l2649). Here were no instructions included so I used the procedures I found on this thread.
This (and I quote):
I used the supplied lead with the red+black clips and the green lug.
I connected the clips to the battery and the green lead up to the green connection in the airbox ( middle pin of 3 pin connector).
Tester read connecting so I held down the mode button, then turned the bikes power button, next thing you know Diag mode!!!
The above worked! It would have been hit or miss figuring out the last part so thanks to those who put it out there! The FI tool read the CO as 0, so I bumped it up to 9. I hit the button and it fired up immediately. It used to take a couple of revolutions to fire, now it was like a half of one.
I tested it yesterday out on the trail and it really seems to have made a difference. It now starts immediately hot or cold and runs a little crisper right off of idle. This adjustment really is a must do if you want your bike to run to its potential. I have the GYTR tool as well, you really need both.
I’m going to keep the GYTR tool for future tuning, but I think I’m done with the CO tool. Maybe someone who needs one can just buy it here, it definitely works. Send me a message if interested. Or if you live near Bennington Vt you can come over and use it at no charge.
