Just took it for a quick spin. It's definatly louder and seems more responsive.
I have a rattle on deceleration as the revs drop below 2000. It's not mechanical but something loose. I checked all the heat shields and they are tight. Suspecting the radiator surround. Not going to stop me riding it but is just annoying. Oh well one thing at a time I guess
No. Definatley not the filter. It was there before. Its something loose. Only happens on decel tho so real hard to track down. Its as the revs drop off something just finds its sweet rattle spot.
