Hello all, just got back into the motorcycle thing after 10 years. My son got a 125 Yamaha TTR and I just purchased a 1999 XR650L so we can ride together. Bike has 2600 miles and appears to be in excellent condition. I have a question on the stock exhaust. It looks like there may have been a baffle or something in the tailpipe. There are two cap screws in the end that do not appear to be doing anything and there are some "grinding" marks on the end. It is fairly loud and I would like to quiet it down with out much expense, just divorced. Any ideas? Thanks.
