Your never alone with.............schizophrenia
--------------- a new slant on the old Malboro ciggy advert? anyone remember?
Anyway, very useful photos, Bob. Always thought there was an expansion chamber hiding in there, it's hinted at, on the cutaway drawing of the GTR pipe in the parts manual, P38. You've confirmed it. At the same time, they went to all that trouble to incorporate a tuned pipe in an innocuous looking silencer and then had to put damn great dents in it to clear the frame, thus upsetting the operation of the pipe !! http://bridgestonemotorcycleparts.com/PDF/BS350PartsManual.pdf
Was planning to split a corroded pipe in my collection, saved me a job. Now we can see what's in there, will have a go at making a mandrel to take some of the worst dents out of my pipes.
