WHAT'S IN THE PACK

The PHANTOM GT PETROL pack documents the combustion twin of our flagship: a blueprinted 125 cc four-stroke in the same chromoly spaceframe. The CAD is modelled around a widely available donor engine, so the mounts, chain line and exhaust routing are drawn for parts you can order today. Drawings, BOM and the 176-page manual cover everything from jig setup to carb jetting and the first heat cycle.

CAD package

Full parametric assembly plus every individual part, exported to STEP, IGES, DXF and native SolidWorks. Engine bay modelled around off-the-shelf donor engines.

Fabrication drawings

Dimensioned 2D prints for every tube, bracket and mount — cut lengths, notch angles, hole tables and weld callouts. Print-ready PDF and DXF for laser or plasma.

Bill of materials — 198 lines

Editable spreadsheet with quantities, materials, engine and drivetrain part numbers, live price columns and a running budget total.

How-to-build manual — 176 pages

Step-by-step photo build order: jig setup, weld sequence, engine mounting, chain alignment, fuel and throttle routing, torque table and carb jetting sheet.
