I've paid between $250.-$400. for these '86-'97 Honda's (the whole 4-wheeler) here in NC. Honda made LOT'S of this model with little change. I've bought 5 in the last 3 yrs, and found 1 engine for $50. Look for one that's trashed/wrecked to get it cheap/cheaper- You don't need anything but the running engine & wiring harness/electrical components. If you don't mind reading - earlier in the thread I showed how to make a sprocket carrier (which you'll need moved over)
