My 400ex is stock and it will run about 87 mph. there is no way they may go 65 but no way 87 your crazy
No, the plastic from a 1999 Honda 400EX will not fit on a 2001 Honda 300EX. The two models have different frame designs and mounting points for the plastics, making them incompatible. Additionally, the overall dimensions and styling of the plastics differ between the two models. It's best to use plastics specifically designed for the 300EX for a proper fit.
the stock 400ex has 29.3 at 6900 rpm
No the 250,300,and 400 ex all have differwent air filters
