Captain, I asked my dealer 2 days after I rode it home from the shop, he shrugged and said "Euro4". So either he doesn't care or its what he says. What opened my eyes was AndyManCam talking about the issues with his Versys, check out his video (Youtube Andymancam Booster plug), jump to 11 minutes if you don't want to watch his very entertaining install guide (really, he's a hoot) and he describes my problems to a T
I will add that I find it very strange that my throttle cable needs constant adjusting... never had that constant tweak with any of my previous 10 bikes, if it's the throttle linkage, it still needs pulling apart by the dealer at the service.
