I went out immediately after the mechanic said it has done was Suzuki Switzerland suggest to fix the problem. In fact, Suzuki found "a" fix to a perticular problem on a perticular bike, what happened is that it fixed the cut-out on my bike too.
I posted a test protocol to make the engine cut-out, and believe me or not: My bike do not cut-out anymore. The strange thing is that my busa has a complete different behavior, and I love it, this is a real Blaster on the road, all of my friends stays behind in the mountains, R1, TL-1000R, GSX 750, ZX7R, all of them !
To be honest, I don't exactly know what they did on the bike, because they don't want to tell anything about it before the corporation knows it and do something about it. The only thing I heard is that it was related with the fuel pump, maybe the filter. What I guess is, out of the factory, the tank is not cleaned correctly and some particles damage the pump.
I will try to find out if I can have more information, then I'll post it here. Keep bustin !
