Re: Why not one more. Snowmobile engine deadtail
Thanks. These little engines are almost to simple. No valves of course, but even beyond that they are engine design at its simplest form. They were kind of the German equivalent to a Briggs and Stratton. 2 stroke though. Made for reliability more so than power. Rated at 15 h.p. at 5000 rpm. Im going to do a little exhaust port work, mostly just cleaning up the rough casting as well as modify a 250cc dirtbike expansion chamber to fit. With those mods I may get up to a whopping 17 h.p. lol. My thought though is that if it will move a 350 lb. snowmobile 30 m.p.h. with all of the rolling resistance of the track, it should be able to motivate a small motorcycle up to 55mph with the right gearing. all of this is guessing only of course.deviant said:This is cool, man. I'm enjoying learning about these motors.
