I have a 2002 Vstar 1100 Classic that I bought used. Under the battery holder, behind the exhaust pipes, there is something that appears to be foam covered in silver/chrome tape. I have never been able to find it in a tech manual and I have no idea if it is stock 要么 was added there by the previous owner. Here are two pictures of it along with a picture of a manual. This item would be right about where the "G"是。谢谢您的帮助。
