The easiest way to get the most performance out of your CR125 shifter kart. Plus a logbook that keeps a note of what worked. Works out the jetting of Honda CR125 shifter kart engines with Keihin PWK 38 and PWM 38 carbs, from the real temperature, humidity, air pressure and altitude. ENGINES Stock Moto and Mod Moto, with a clamp-on air filter or an airbox with or without foam, and with or without a fuel pump. RESULTS The jetting recommended for the conditions and the engine you have set: main jet, needle type and clip position, and pilot jet. The main jet also comes with its real value in decimals. Plus air density, density altitude and relative horsepower. Three fine-tuning adjustments of ±10% on high, mid and low to adapt it to your engine and how it is built. The values assume a #6 slide. CONDITIONS The weather data, two ways: from the nearest public station, with how far away it is and how old the reading is, or typed in by hand. It works just the same with no signal. TRACKS 143 tracks built in, starting with the ones in the United States. Pick yours and the altitude fills in on its own: the altitude of the track itself, not of the town, which are usually different. Search by the track name or by the town. ENGINE Engine class, airbox, fuel pump, oil mix ratio and track type. LOGBOOK Saves every run with its conditions and its jetting, and afterwards you note what you actually fitted and how it went: lean, good or rich, separately for low, mid and high. Laps, best lap and maximum RPM too. It exports to CSV and moves from one phone to another. UNITS Celsius and Fahrenheit, metres and feet, and mb, hPa, mmHg and inHg for pressure.

Best jetting app

I've been using this app for a couple of months now. I tested it out at Phoenix and El Paso, TX. So far, the jetting parameters are spot on. They tend to run on the rich side, which is always ideal for these expensive engines. I do run them at 1.5 richer just to be on the safe side as competition is more about the driver not the engine out here in El Paso with the Border Karting Association

This app is good. But I just upgraded to a gravity feed fuel system. I do not know how this app is going to work out because it does not have the gfs on their applications.

Ignore the negative review. I see what he's doing. It's the corrected altitude which is what is used for jettting anyway. Will test and see how it works.

Good basis app for starting points on jetting. All jetting is unique to conditions engines and areas but this app is very useful.

Version 2.0 LOGBOOK Saves every run with its conditions and its jetting, and afterwards you note what you actually fitted and how it went, separately for low, mid and high. With laps, best lap and maximum RPM. Exports to CSV. TRACKS 143 tracks built in, the ones in the United States first. Pick yours and the altitude fills in on its own: the altitude of the track, not of the town. CONDITIONS The weather station data and the values you type in, on a single screen. No more going back and forth between two tabs. FIXED • The position screen did not work: the system had stopped reporting the position years ago. • The app was drawn cropped on modern iPhones. • The values on Weather ran off the right edge of the screen. • Fine tuning was left written into the calculation table. • Usage data no longer leaves the device.

Version 2.0 Aug 21
