Ok so hear me out. I’m new to the motorcycle world, honestly only rode a handful of times. I recently purchased an 03 shadow spirit 750 with a nasty tick for $300. Bike is in decent shape except for that. I’m a mechanic by trade so I tore the engine down to find a bent rod. I started searching for a used engine found one 750 from an 04 went and found it locked up so I obviously didn’t buy. I have found a bunch of 600cc engines from similar year models and since I don’t have any attachment to the 750cc, is it possible to put the 600 in my chassis with minimal effort?
