thanks all,
i have some videos of the sound with the baffle in, and shall have some with it out, will try post them somewhere....
the corrosion is the next thing to tackle, recommendations on what to use?, my friend suggested some spray on coating that bakes on i.e. spray it on, take it for a ride to heat the pipes etc....
I have a wire cleaning set to gently get the rust off, but not sure if a chemical cleaner would be any good?
shall look at the center stand rubber as well..
thanks
