Pinti Motori software, made for people who tune two-strokes.

Spillo

Dell'Orto VHSH 30, VHSB 34 (Rotax Max karts too) and VHSB 39 carburetors

2-day free trial

Enter your setup, change one part and see right away where you go rich or lean, by how much and why. The calculation uses the real dimensions of the catalog parts: the profile of every needle, the needle jet bore and the main jet.

  • Every part in the menus. 117 K and U needles with their dimensions, DP, DQ and FN needle jets, main jets, slides and floats, with their sizes.
  • Stage by stage. From idle to wide open: whether the main jet or the needle is in control, the clearance between needle and needle jet, the biggest main jet worth fitting.
  • The setup sheet. Save each test with track, altitude and weather, and turn it into a PDF.
  • Phone and computer. It installs like an app on your Home screen and works without a connection too.
  • Dell'Orto PHBG and PHDG coming soon. With your key you'll find them in the program at no extra cost, along with every update.
How to install it on your phone
  1. iPhone: open Spillo in Safari, tap the Share button (the square with the arrow), then “Add to Home Screen”. Always use it from there, and activate your key from there.
  2. Android: open Spillo in Chrome, tap the three dots at the top, then “Install app” or “Add to Home screen”.
  3. Computer: open it in Chrome or Edge; the install icon appears in the address bar.

The first time you need an internet connection. After that it opens even at the track with no signal.

Read the Spillo guide (two minutes): how to use it, and what not to do so you don't lose your key and saved setups.

The trial and the key

Spillo opens with a key. To try it free for 2 days, message me on WhatsApp (the button above, or “Ask for the trial on WhatsApp” in the program) and I'll send you a trial key. In the program tap “Activate”, paste it and tap Activate. You only need internet at that moment.

If you like it, I'll send you the full key, which is good forever: for one device (phone or computer) or for two together. If you change phones or clear your browser data, enter the same key again and it moves over by itself, up to 2 times. Keep the message with your key.

Always check the program's advice on the engine: a mixture that is too lean can seize it. Not made or endorsed by Dell'Orto: the name is used only to say which carburetors it works with.

Expansion chamber program: Two-Stroke Exhaust Designer

The expansion chamber, from engine to sheet metal. For Windows 10 and 11

In development: available very soon

Work out the dimensions, test the pipe on the simulated dyno, bend it around your bike and print the templates to cut, or send the DXF files to the laser.

  • Pipe. From exhaust timing, rpm and port size: header, diffuser, belly, baffle cone and stinger, drawn with dimensions.
  • Dyno. The simulated dyno shows you where the pipe pulls and how the power band moves when you change the dimensions.
  • Shape. Bend the pipe over photos of your bike, with every bend written out in numbers.
  • Cones. Every piece laid out flat: PDF to print at 1:1 scale and DXF for laser cutting.

As soon as it's ready, you'll find it here.
