Quote:So before spending all the money, do as Gnasher suggested and give Yamaha a call to check the emission figure for your bike, if its under 0.15 then all it will cost you is £60 for a Certificate of conformity which you then upload along with a copy of the first page of your V5 on the TFL website -But (as I said) Yamaha will give you a figure which is over the limit. Been there, done that.
NOX figures were only entered onto V5s later, so only the manufacturer can provide an official figure.
Of course individual bikes might give a lower NOX figure, especially if the mixture has been adjusted, such as with a non OE air filter. But then you need it individually tested, and for that you are at the mercy of the only approved testing workshop..... who have you by the short and curlies :eek
