I have a 05 honda 400ex bored to a 426 a hot cam full yoshimura exhaust and more and a guy wants to trade me for a 04 polaris predator 500 with a yoshimura slip on I believe I just don't know much about them so If someone could help me out! On what to do

 

Imo if the Honda runs good keep it.Why trade for a year older model.Plus the Predator like the Outlaw needs frequent valve adjustments and it uses shims unlike the Outlaw.
