Ok, I have seen many "This can go so fast" videos on Youtube lately, kids claiming to have very fast scooters... Now, let me introduce you all to a build (by either a genious or a complete madman!). A little info first: Scooter make: Gilera Model: Runner Was earlier 50cc, is now 80cc ported engine etc., selectra ignition, "custom built" CDI box (can make many changes on it, not seen). Cylinder: 2Fast4Race 80cc Crankshaft: Titanium Carburator: GoKart type Airbox: GoKart type Exhaust: Built by builder (Custom, est. cost around 1600US$), only for that specific engine -not seen on picture and not used at that moment. NoS: Yes. But never used. Maximum RPM reached: 20.000RPM and then the Variator spring "left the engine". Speed: 170+ (Km/h). Torque: Somewhere around 40 on the rearwheel.. Buildtime: Unknown.. Graphics/paint job: J-Style (Sweden) Cost to build/modify engine and parts: ~70.000SEK (somewhere around 7000US$).
