My ferris needs a new engine and am considering a Kawasaki FX EFI model. The original engine is FH721V.
Firstly are there any modifications required to the existing wiring loom if a fuel injected unit is added or should I stick with a carb model?
Model no FX730V EFI has a little less power and torque to the original and FX850V EFI has a little more - additional 4.5 ft lbs torque although I’m yet to check if the 850 fits, it’s a few inches larger all round. Any issues with additional torque?
I appreciate some advice. Thanks.

Nursing school is tough—I feel you! I relied on services like Nursing Paper a few times, especially when it came to nursing school homework. They were lifesavers when I couldn’t balance everything. One thing I noticed: always check reviews to make sure the service fits your needs. With Nursing Paper, I found their work very detailed and aligned with nursing standards. But remember to give clear instructions to get the best results. What’s stressing you out the most right now—essays, quizzes, or something else?

Why do you need a new engine? How many hours on original FH721V? Why do you want to go to EFI engine?

Besides the wiring, which will no doubt be different, you need to check crankshaft dimensions, muffler fit, and engine bolt pattern. You need to think this one out.
