Hi, I know this is an old topic but my pipe also appears to have gone. It's quite rusty and cleaning the bike with gunk and then riding it has shown me a whole new World of pain, so much oil!
The part appears to be no longer in stock by anyone although I will try my local Yamaha dealer tomorrow when they're open. Did anyone have any luck in sourcing alternative suppliers? It seems strange that Yamaha would stop supplying something that is so important!!
Thanks in anticipation.
