This is a track day event for geared scooters (like Vespa, Lambretta, Heinkel, etc) on a time trial basis on the 5.1km long Nuerburgring GP-track..But of course almost everybody goes for the quickest achievable lap time:Examples: Myself Vespa ET3 Polini TwinInduction133: time 3min30sec avg. speed: 88kphCharlie Edmonds: Lambretta 204cc: lap time 2min45sec, avg speed: ~110kph Tony O'Brien: Vespa 90SS: lap time 2min47sec
Through the glass insulator of the Colortune you can see the combustion flame. Its colour indicates what the fuel-air-mixture is like. This way you can adjust your engine / carburettor. Rich mixture --> Orange or Red flamecorrect mixture--> blueish, yellow flameLean mixture--> blue or white flameThe video is just to show the principle, to really perform a setup it s neccessary to do that under load (on the road or safer on a dyno).
