Nat67,
Having read through many more posts on there ere forum thingy, - I'm at the Mother in Laws for the weekend. one of the penalties imposed for buying the bike - it seems to be the Ramair System that is most popular as a replacement air filter. Accordingly, the K&N replacement has been cancelled in favour of the Ramair. Unfortunately, I'm on holiday with all family including 7 grand children from Friday for 2 weeks, so I'll have to wait until I return to make all the modifications and chance my luck with the Tune Ecu program..!
