Hey guys.... been gone a long time and its time to dust off the ol' two stroke. I am 26...havent raced in about 5 years. Before I hung up my boots I was a top 5 am rider. I ride here and there when I can on friends tracks or at open practices. But here is my problem... I have gained quite a bit of weight since I rode competitively. I am 6'2" and weight around 220lbs which is fairly big for a motocross racer. I definitely need to get my suspension redone. But I feel as though the motor is letting me down. I can just feel the difference my weight has made on how it pulls me around. A 450 would be ideal but I dont have the cash to buy one and I would never sell my two stroke anyways. What are some of the best mods I can do to get more power out of it other than a big bore kit? I was thinking of sending the head and cylinder to Eric Gorr or procircuit for a port/polish job and some head work. I also vaguely remember reading on here that using a yz250 piston is good for 1hp. The bike is an 06 RM250 and already has a procircuit works pipe and factory sound silencer and boyesen reeds. Other than that it is stock.
