Yeah I also thought about this. But luckily someone sold me his Kev O2 Controller for 10€ so I will try this first.Well, if you're willing to pay shipping costs, he may agree to do it. You just need to agree in advance.
Not a bad idea. But I have no experience in flashing ECUs. Do you know where to get the flashing hardware?Buy the stuff to do the flash and pay vcyclenut for the tune. Then you can both do others in and around Germany.
You are right. Yesterday I tried it with a running bike and the butterflies are opening much smoother. I don't know if I got the reflash because I bought the bike about one year ago. I'm planning to go to a Yamaha dealer to check this.Have you started the bike and watched the initial opening? The butterflys aren't at idle so you may be fooling your self into thinking the problem is bigger than you think it is. If it still jumps like that when idling, then read a little farther into it. Have you had the Yamaha reflash done at least? Smoothed mine out tremendously.
