I have a yzf600r and i just had the second gear rebuilt ( well the whole trans basicaly) and now when im in second which it shifts into and out of fine it makes a whining sound. it only makes it when i let off the gas around 2000-5500 rpms. does ne one know what it could be or could it just be thatthe gears havent seated yet. i only put about 75 miles on it since the rebuild because i bought my cbr while it was being rebuilt and well the cbr is just better. ne suggestions?
