Задача
Peru is a hard market for carburettor work. Arequipa sits at 2,335 m, Cusco at 3,400 m, and Puno at 3,800 m, and a dealer may serve riders who travel between all three in a single week.
Without a reference, mechanics were enlarging or blocking jets by trial and error, and often by drilling. Bikes came back with plugs fouled black at altitude, or with a lean surge the owner described as "the engine is breathing wrong".
There was also a commercial angle: the distributor sold carburettors but had nothing to sell to the rider who only needed the bike to run properly at altitude.
Наше решение
We built a kit around the three altitude bands that matter in southern Peru, and put the knowledge inside the box.
- Contents: three main jets, two pilot jets, one needle, a bowl gasket, and a set of brass set screws — enough to cover 2,000 m to 4,000 m without drilling.
- Reference: a printed Spanish card with the baseline setting per altitude band, plus a QR code to a 20-minute installation video.
- Testing: each jet combination was checked on a bench at simulated density altitude, so the recommended settings were measured rather than extrapolated.
- Packaging: a compartmented box with each jet in its own marked slot, because loose jets get mixed up on a workshop bench.
Результат
About 1,400 kits shipped in the first year. The distributor reports that installation time dropped by roughly 25 minutes per bike, mostly because mechanics no longer test-ride twice to confirm a jetting guess.
The kit also gave the distributor something to sell at a low price point, and it now accounts for a meaningful share of their walk-in traffic.
Altitude changes the mixture, not the carburettor
Nothing inside the carburettor changes when a bike climbs. What changes is the mass of air passing through the venturi for a given throttle opening. Less air mass, same fuel volume, richer mixture — and the higher you go, the further the mixture drifts from the target.
At 3,800 m, air density is roughly 35% lower than at sea level. A bike jetted at sea level and ridden to Puno will be running a mixture that is far too rich: black plugs, poor fuel economy, carbon build-up, and a exhaust note that sounds flat.
Why drilling is the wrong fix
Drilling a jet is irreversible and imprecise. The hole is rarely round, the size is not repeatable, and once the original jet is gone there is no baseline to return to when the bike moves to a lower city.
A jet kit keeps the original calibration intact as a reference and makes the change reversible in minutes. That matters in a country where the same bike may be used at 2,300 m one month and 3,800 m the next.
Why the printed card still matters
The QR code is convenient, but a workshop with poor signal still needs the numbers on paper. The card lists the baseline setting per band, the direction to move when the plug reads rich or lean, and the correction per additional 1,000 m — three pieces of information that cover most of the cases a mechanic will actually meet.
