This is an AMA certified race machine built by Scott Venning. Only 35 hours on this machine after a complete overhaul and rebuild. Everything inside the engine and out is aftermarket...too much to list. A steal for less than $5,000. I have found that this machine optimally runs with a 50/50 mix of racing fuel and high octane. Buyer beware --- this machine is not for the immature or careless. Too much power and too fast not to respect it.
