You have to challenge them with the likes of danger and fit for purpose. I too struggled with them as I requested a new ECU when the bike was just over 3 years old. I was possibly the most loyal customer of Suzuki since 98 with 24 bikes and I wrote a very long and strong letter to them. They came back with the usual as a good will gesture and gave me one. That is rubbish this should have been a full recall of all the early models with that ECU.
Those of us that bought this great bike when they first came out had to also endure the recalls etc yet they still dragged their feet when it came to releasing the ECU's.
I hope all goes well for you as when you have the new ECU you will really like the bike, mine is now nearing 30,000 miles and I love it.
