  1. Check out the Rotax E-TECH - 800cc and 160 bhp. Skidoo snowmobiles use them with less weight and better fuel mileage than equivalent (1200cc) four stokes. Fuel is injected after the ports have closed so there is no smell. Rotax even have a turbo version for use at high altitudes. Exhaust has a variable height valve to give a wider power range. Inlet has reed valves to prevent blow back. Fuel is not run through the crank case so less oil is needed to keep the bottom end happy. Its also possible (with a small blower) to have a wet sump where air and fuel never goes into the crank case. This works well with V and Cross format engines.
