I had a dealer fit the Akrapovic system to my 2024 V4S together with the upmap and ever since I've got very strong exhaust fume smells. This wasn't present before. I was expecting some given the absence of the cat but everything really stinks, clothes, boots, luggage, everything. I can't find any obvious leaks from the system. Is this really to be expected? I've not picked up on anyone ever mentioning this before. Sounds daft but it's really annoying me! If there's nothing else I need to be checking then it's going back in to the workshop..
the bike i test road had a full ackra system and it did have a octane smell but in a good way I bought a rally v4 multi with standard exhaust and it has no odours...........except me ! so your situation would seem normal
Run a 1260 with no Cat and on initial start up it does smell like a motorbike should and expect with more fuel on a cold engine.. Once warmed up its not really an issue tbh.. might be worth getting your bike looked at/mapped properly/ check what is really happening with the fuelling by an expert.
