I started with a 92 Trail Boss frame and an 87 Trail Indy chassis. Both of them cost about $800. The motor needed to be rebuilt and the frame had everything I needed. Some of the parts I was able to return to the dealer like the sled chassis and gearbox and motor out of the wheeler.

Yep, you guessed it's a 488cc Fuji motor. Why fan cooled you ask? Light weight and basically it's the same motor as a liquid cooled 488 but a lot less hassle. Generally we start by stripping the frame and mock up the motor and pipes. Then add the jackshafts, keeping proper clutch alignment. We added jackshaft brakes at a later date.

This is what you get after spending $400 on tires on stock wheels and a whole lot of time on welding. Pretty neat huh? It's nice having a Polaris dealer and mechanic on your side. We run Decker pipes (hand fabricated) 38mm carbs and Power Mist fuel. That's all of the mods for now, where thinking about allky for next year.

At the back tires this thing will have about 15/1 gear ratio, not factoring in the variable clutching. We do all of our own clutching and gearing by test pulling a pickup truck, applying the brakes gradually. We do this until we get the motor to run in the powerband, about 8600rpm.Still needs to be fitted with plastic (2000 Scrambler) and taken apart to get sandblasted. We ended up painting this one with a 95' Dodge Driftwood color with red accents.
