I have a Yahama Enticer chassis with a 340 Ski-Doo in it. The engine was put in very well. I can prolly get pics for you if you want. I also have a 440 Invader, but that will need some mechanical work done to it. Just let me know if you want to see pics.
Ya ad reads:300 liquid cooled, studded track, hand warmers, elec. start and trail ready $850 (815)459 9555. By the # I would say it's in Crystal lake Il. 40 min from Wisc. border
