Hey guys just bough an 03 YZ450F for 500 bucks. Everything is apart but the motor, he never went into it. Basically what I have diagnosed is that he was burning oil and then fouled a plug. He though it was the timing chain but thats fine. Valves are great too. So basically ive ordered a new cylinder (plated) and wiseco top end kit. Bottom end is solid. So what I was wondering is. Whats the valve clearance for the bike? Torque specs for the head and cylinder? Ring Gap? Oil Capacity? Break in Oil? Jetting (stock)? and, is the bike really a beast like people say? Thanks guys!
