So I picked up a used 2018 with no exhaust ... how bad is it not to have one and should I get a new muffler or do the cat delete and get a new ECU and injector? First bike so I’m kinda lost..
I noticed that the top of my chain has been staying shiny so I took it apart..... I found that the bottom chain guide is rubbing against it. The chain is at the right tension.. so what would cause this and is it something to worry about.. I have pics of the guide and the wear on it .
I just bought a used 2018... and it had the Exhaust taken off to make it louder when riding I’m only getting 20 something mpg is the exhaust the problem or something els? I am only using 90 octane also because that’s all I can get around me..
