Hi and welcome
Some one on here has done one thing or another to every type of pw on the planet. I searched just like gseric69 suggested and found over 200 threads with your pw in mind. Is there a particular question you have?

I posted last month that My orange kfx was running on 18v with no issues for about 45 days. The very next day the c-board went boom. That's the only mod on the kfx I've tried. My shop is unheated so it'll just have to wait until spring.

I have added a few items to my son's KFX. But I've kept it at 12v so far.
The next trick is going to be the Duratrax motors, heat sinks, and a change from 19T to 16T gearboxes. It still should go 20-30% faster than stock, but with more torque for his hill climbing.

I think the next wiring job will involve a 24v scooter controller with handlebar twist throttle and hand brake, and 21 or 23 turn Titans, with heat sinks and fans. Maybe a limiter resistor to keep him from full power for a while. And turn the existing go pedal into a dead-man's switch...

The circuit boards in these can be tempramental. Some folks have run 24V through them and not had any issues, and some, like rockjessemax, have toasted it on 18V.

I personally don't like 24V due to the frequent failure and replacement of parts it usually causes. Also 24V is a bit much for the stock 14awg wiring, and 10awg wiring should really be used for that much voltage.

Certain steps can be done to help the parts last longer, such as a true variable speed throttle with a scooter controller, adding a seperate brake pedal, and adding heat sinks to the motors. All of this has been discussed on many other threads, and the information can be found by using the search feature and reading the FAQs.

Another issue is the space for the batteries. If I remember correctly, the battery compartment in the KFX Ninja's is pretty tight, so you should measure to make sure you have enough space for the batteries you plan to use.

The circuit board can be bypassed on these without any problems. I rewired mine to a more traditional direct wiring and it worked fine until it ate the gearboxes.
