Well folks, I've got a 400 scrambler sittin in my shop with a blown motor. The cheapest complete motor I've found locally is over 500 bucks, and it isnt even running. My genious idea is........ One of my buddies has a complete, running motor out of a wrecked polaris xc 700 sled. recent rebuild, like 300 miles ago, in the neighborhood of 140 hp, that i could buy for less than that. My ? is.... What do you guys think of the idea, the clutches are basically the same, just different springs, the 700 is obviously wider but i'm not to concerned about that. I have an extra swingarm layin around that i was thinkin could stretch somewhere like 6 inches. Keep it alittle less wheelie crazy. Just wonderin what you guys think of the idea. Any feedback would be great.
