Hi, My son started racing microds ( dirt) this last summer. I was wondering if anyone else on here is into the same type of racing. Being new at it I am just trying to pick up as much info as I can. It seems most of what I find is geared toward asphalt and a factory built kart. What we run are home built karts on a 1/10 mile dirt oval and depending on class either a Honda GX120 or a Honda GX200 engine. We did very well for our first year but still just looking for ideas and I know its a bad thing but opinions on some things (tires etc) is there anyone out there running this type of kart.
