Hello everyone, this is my first post here on Thump Talk. I have an 1998 Yamaha WR 400f and it has an White Brothers E series exhaust. I am looking for spark arrestor for it and have not had any luck finding one. I have been searching Google and looking all over Ebay. I also know that White Brothers no long exist as a company because they where bought out. Can anyone help me finde one or know of a make shift way of making one ? Thanks for you time and I look forward to your responses.
