Thanks for the replies and the warm welcome,
In the end i went with SE heavy breather air filter (its not standard on the UK model) V+H 2-1 Powerpipe in Chrome and the new Powervision from Dyno Jet. I had to fit the quiet baffel in the exhaust as it was just too loud, it is just right now, and the performance difference is fantastic, the bike runs cooler and the econamy has gone up, nearly 200 miles to reserve with normal stop start riding, only snag was the Powervision did not come with and maps for the SE Fatbob, but a phone call to Dyno Jet UK sorted that and two days later a custom map was e mailed to me.
Have also had the frony fender replaced under warranty (with only a week left) due to corrosion around the joints, have also got a new rear fender on good will as this is also corroding around the edges and fixings, not too impresses with the finish as my bike hardly see any rain!!
I will post some pic as soon as ive cleaned all the bugs off.
Cheers
