Various questions regarding Karting and technique

[lovef1]

hello there fellas,

i recently started racing karts, and up to now I've participated in 3 races. My lap times are pretty slow compared to the seasoned drivers, but I believe with a bit more seat time I could eventually be on their pace. The thing I noticed is my steering input is 10 times more than the guy up front. My kart always oversteers in the high speed stuff and understeers in the slow speed corners, and as a result I need to use different lines to accomodate the karts handling charachteristics. Is it my lines, throttle and brake appllications, set up or is just down to me being crap? Any advices are very much appreciated.
