Well got the bike in march 2004.Did not have anything done to it yet! Rode it like that for pretty much the season,but at the last month of riding I bought myself a nice B day gift . Well I got a jardine rt1 race baffle slip on and K and N filter. Now that it is not being riden I put a Factory jet kit in and changed out the sprockets and chain on. Now I just need the snow to go away and for it to warm up about 40 degrees,then I can see what she got!!!!!!!!!!!
