      I need to replace a 250cc engine on a carbureted bike, but I only found an EFI engine.

      There’s no reason it won’t work, they are the same engine the efi stator is a higher output that’s the only thing I can think of. You have the carbs, manifolds, wiring etc should just fit right in.

      Replace the stator of EFi to Carby Stator , so use your old carby stator
      And also use your CARBY flywheel
      This is because the EFi flywheel does not work with Carby CDi’s

      Next thing, use Size 20 pilot jets and 92.5 + 95 main jets

      See full tutorial of jetting here

      Don’t throw away the old 250 engine, you will NEED IT for spare parts in future 🙂

      Can you give me a hint on how to loosen the flywheel nut? The manual says that I have to lock the connecting rod with something, but I don’t want to remove the cylinder head, cylinder, and piston.

        I ended up using my power tool; I don’t like those noisy things, but I had no choice.

      I ended up using my power tool; I don’t like those noisy things, but I had no choice.

      We use a tool called “ROTOR” locking tool , as i don’t trust “power guns” near motorcycle engines  (too much torque on some of them and a crank is expensive part) ,

       

      it works with clutch baskets too.

      Hi, I forgot to mention that the EFI engine worked well with carburetors. I replaced the stator and the rotor to get it running.

       

      Thanks. 😀
