I got that. The fuel controller is on and has been for 6ish months. I installed the tuner, cam, yoshi exhaust, and the finbro head. Ill bee putting the piston and cylinder on first week of Jan when i take vacation.

The fuel controller controls injector pulse width in microseconds and that's it. No timing. You can set redline and calibrate TPS.

The built in MAPs are decent but i don't have a wideband (installed yet) or dyno to confirm. It 100% has better acceleration and top speed with the preset maps once you add the corresponding mods.

Reliability is good so far, the spark plug looks good, fuel economy has gone down a bit, and I've held 50MPH for 4-6 miles in 90* weather with no melted piston.

As long as you treat it like a 125 trail bike and don't beat the crap out of it constantly you are going to be good. If you want to run wide open all day every day id get something with a wideband auto tune. For grocery getting and cruising its more than adequate.

good advice ^. def get a wideband meter installed for setup/tuning.. and then it can be removed.

Im.going to have to think on this. It seems like the aracer is more of what I'm looking for but this kit does not seem that bad.

honestly, i think you'll be fine. just monitor it initially. I run my 143 w cam and exhaust on a larger injector and an efie, which is the most dumbed down way to control fuel, and its zero issues.

I probably should ride it around stock for a bit. It hasn't even gotten to my house yet and I am already trying to soup it up lol.
I don't want a bunch of mods, just give the engine a bit of extra kick and i feel like i could do that with just a piston/cylinder and fuel controller combo.
