I am getting a 87 250r in a couple of weeks. I have $3,000 to spend on mods after I get it to set it up for MX. Please give me a list of the most needed things to make this thing a great MX bike. I don't need wheels or tires as I have new MX Razr's on ITP C rims and the quad has a new clutch. Everything else is fair game. I would like the bike to have a good ammount of torque (big bore and/or porting). Obviously suspention is a must but I would like to know what is the best bang for the buck as far as setting this up. Please give me a list of parts and if possible some prices. Thanks in advance!
