Guys , as Shiney said , the difference in weight between the Delkevic and the standard pipes is astonishing and must impact on performance. In terms of the noise factor I am really happy with the change , while touring along its just a gentle rumble , but give it a hand full such as overtaking or going down in gears and it really sounds like a motor bike should sound . I also love the way the Kevlar pipes look .
Shiney, to answer your questions in relation to the John Moorhouse seats , I have booked my seat in with John ( he is quiet busy , 2 weeks wait to take the seat to him) and he has quoted me $180 to re shape to fit my bum , and he will need the seat to be dropped off on the Monday and should be ready on the Friday.
He has asked me to bring along a photo of me riding the bike to get a better idea of the shape needed. When done I will be happy to report back on the success or lack off.
