Hi,
I have a XR 650R that I am planning on racing (200 miles), 50% of the course is sand and whoops, very technical, 50% has flat wide open roads, the bike has a stock engine, the only thing added to it are the fmf header, procircuit t4 pipe and jetting, the sprockets size are 15/45 and the rear tire size is 120/90-18, is that good enough or should I change some of that????????? THANX!!!
