I have a 2001 KTM 125 SX engine just sitting in my shop. They put out hp in the mid 30’s and are super light. Would adapting it using a chain drive or belt drive be recommended for an ultralight application?

I converted a Kawasaki KX100 engine for paramotor use. I kept the gearbox but removed the gearing except for the 3.4:1 first stage which normally drives the clutch, with the prop shaft and support bearings mounting where the clutch cover used to be.
Cool. I want it to go in an affordaplane or a minimax. It can be upgraded to a 200cc easily also. I raced KTM’s for years so I know they are tough engines. I’m just brainstorming and trying to get airborn on a budget. I’m a former F-15E mechanic as well so I’m not clueless concerning aircraft.
One issue with dirt bike engines is the narrow powerband, all the torque is at the top and. On my paramotor it was a fine line between enough prop pitch to hold the rpm down at full throttle vs. too much pitch so it never got "on the pipe".
