Kraptanaman Posted September 4, 2018 Posted September 4, 2018 I changed my devil exhaust system to a standard one on my 1100. When replacing the exhaust gaskets I found disks behind the gaskets that restricted the port size. Any reason? Do I bin them? I have never come across this in my life. Quote
