ELF Masters from Europe; Formula One Drivers Racing 100cc Piston Port Powered Karts Indoors

This is awesome footage of some old school Formula One drivers racing with JICA piston port powered karts. These F1 drivers are moving pretty well with only 100cc's of power. A JICA engine is the Junior 100cc ICA engine too, not even the full Senior ICA reed valve engine. The racing is excellent and very closely matched. Enjoy!
