How do I get a new heat shield?
A shopper on Aug 31, 2016
BEST ANSWER: We unfortunately do not stock, nor do I see availability for a replacement heat shield. In attempting to contact Yoshimura, their website is non-existing, I apologize for the inconvenience. At this time i'm unaware of how to contact them.
