I have found a 400ex for what I believe to be a good buy.

New body (aftermarket), exhaust, bored block, hot cam, new tires, chain, sprocket, really clean (reciept for motor being professionally built.

Est speed 75-78mph. Includes helmet, goggles and chest pad.

I'm new to the ATV world, so someone tell me what this would be worth, and what specific items I should check before purchase.

Thanks in advance.
