About 2-Stroke ToolKit

This toolkit offers some basic two stroke engine calculators in hand but also extends to some advanced as well (Tuning menu).

You can calculate easily and fast the oil quantity by dragging two bars without entering numbers with keyboard. It can store settings for up to 4 motorcycles such as fuel tank capacity (tap to change), oil ratio and the name of the bike.

It also offers a Speed Calculator based on your gearing and wheel dimensions (Gearing calculator). It outputs the speeds in KM or MPH in a 2D table in relation to the RPM (max 15000rpm). You can also save up to 4 bikes' gearing settings.

The tuning menu (in-app purchase) will allow you to fine tune your engine using the following:

1) Calculate engine's time areas for both inlet and exhaust - BMEP
2) Calculate the theoretical carb size based on rpm and cc
3) Calculate theoretical values for main jets based on altitude and temperature (knowing your base settings of course)
4) Calculate and present TA (timearea) and exhaust degrees in a 2D table with fixed height and variable width or the opposite
5) Calculate exhaust dimensions and hydroformed sheet
6) Calculate reed valves with different materials, dimensions, characteristics etc
7) And finally, a how-to guide to modify your Yahama YPVS controller with some basic soldering skills in order to fine tune the power valve opening and closing points, valve speed etc. A table is shown with all the values and combinations

For any suggestions please let me know!

A "free" app that you have to pay to use the features of. Disappointing.

I have used the free version of the app for several years now, considering going good paid just too support the author. It does everything I need in a very simple UI. Low permissions required which is always a bonus.

Jamespaul, you have not done it right. All my calculations are spot on. Congrats to the developer for an excellent work which is also free. Thank you indeed

This app obviously has incorrect coding. Anywhere else you type in regular or certain oil mixtures into a calculator apparatus of some sort you will get a different ratio. For example the 42:1 ratio for five gallons is about 15.24 ounces of oil to gas in the real world, but on this app it says it is "19 ounces." Now I'm not a genius but that's false. Giving out false measurements and then supporting them can seriously destroy someone's equipment.--- I did have the sources put in all US specifications-----
