I posted this under the Dual sport site but did not know if I would get alot of responces. I wanted to hear some experiences with exhaust on the 650L. I have found that Big Gun, FMF and White Bros make exhaust but that are hard to find for the 650L. I have found alot for the 650R. I also wanted to know what kind of frame mod's need to be done on the 650L to fit an Acerbis 5 gallon tank?
