Sound's like what you need is a fuel injected 4-stroke. I have 3 Yamaha VK Pro's in stock that have a 1000 cc 3 cylinder 4 stroke engine. This machine is designed to haul, pull, tow (trailers and other snowmobiles) and tour. Lots of storage, lots of power. Plus they're environmentally friendly, and get great gas mileage! Call me Monday @ 509-548-5881 or 509-421-6501 and I'll tell you more about them. Or go to
www.yamaha-motor.com and check out the VKPro. We sell tons of 'em to ski resorts, the forest service, and adventure touring companies around here.
