  1. Hello, everyone. I've got a 2023 R7 with 2500 km on it. Two days ago I took it to get dyno tuned after taking out EU 47hp restrictions (air filter and velocity stacks) Today my engine blew up on the highway. I was riding in 6th gear when my check engine light started blinking, oil light came on and the bike started rapidly loosing speed. I pulled over immediately, shut off the engine, called a tow truck. I turned the bike on one more time on the side of the road to see if it would start. It's clearly running on one cylinder, smoking out of the exhaust and smells like oil, I will attach a video. I think at least one cylinder is totally blown. The tuner insists nothing could be wrong with the tune. What do you hear from the video, any ideas? Is the motor totally blown, what could be the issue? Blown piston rings, injectors, vacuum problem maybe? In order to change velocity stacks, I had to take out throttle bodies, disconnect vacuum hoses and injectors. But the bike ran fine on the dyno and two days after that it was fine too, so I don't think I forgot to connect something, that would be apparent earlier.
