Hi Everyone,<?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o> <o></o> I am new to Adventure Rider. I have a stock 2001 XR650L. I hade been riding my bike for the last couple of years and I am now starting to get the itch to start modifying. I have added a windshield removed the passenger pegs. I have seen that a lot of people have made the following mods<o></o> Smog-off kit <o></o> Air snorkel removed, replaced air filter with a Uni-air filter<o></o> Jetting<o></o> <o> </o> Everyone says that these mods will improve performance, but I want to know what the advantages / disadvantages are. I saw that most of the people who have done these mods have also changed their exhaust. I dont plan on changing the exhaust (not yet atleast!! )<o></o> <o> </o> Any help is really appreciated. <o></o> <o> </o> Thanks!!
