Hi devinda, the national kart championship was last run in 2005, the main reason it died was there was no place to run the karts, we last used independence square, the classes that were last run were the yamaha and the international class. The possibility of running a championship again is being looked at but once again location is the problem... if a championship is run the chances are it will be a yamaha class (cos that is the most common engine available in SL and the cheapest available one here).
We did run a yamaha go-kart (fitted with a clutch) at the speedrome but it is way too powerful and there is no way u can use even 70% of the power, but it was a fun drift session :-D
