My plan is to replace them the day the warranty expires! I have been advised by two different sources that re-jetting is not necessary but I will follow that up nearer the time. I agree that having more volume makes cars more aware, and a friend was knocked off when a car driver said he wasnt aware he was there, since when he always has loud pipes.
I ride often in a group of six, one Bonneville, one Fazer, one Daytona (I think!), one Harley, one 250 Dragstar (hubbie's), and my 650 Dragstar. The Harley is the bike that cars seem to move over for! You always know where he is when riding together. And his pipes aren't the loudest I have heard on a Harley.
It was quite funny that a work colleague said she saw and heard me go roaring past her house the other evening so maybe the bike sounds louder than I think. She knew it was me as I have a quite unusual pink bike jacket and a champagne coloured bike, which you dont see too many of, round here at least!
I would like to know how you get on with the replacement though. Goff tells me it is quite simple and I am sure she knows what she is talking about. Me...... I am very unknowledgeable and don't mind admitting it. What year is your bike?
Take it easy.
