Hi guys can u help
Had a 2015,2019 and now have a 2021 plate and when slowing down below 3000-4000 revs the new bike makes a horrible whining noise but goes when the clutch is pulled🤔🤔 nothing like the super noise the 2019 used to make 🤬🤬 is this the new ulezz rules in the European market that has added this dreadful whining noise. Please help? Hopefully this makes sense as just ride bike and no nothing else🤦♂️😂👍🏻 cheers guys
