Just purchased a '97 KX 250 and would like to know what the ideal/standard setup is ie. jetting, air, sprockets etc. It came with a full FMF Gold series pipe and currently running 13/48 sprockets. I find it very quick through the gears (holding on like hell) and am in top gear before i know it, with little top end.
Appreciate any info, many thanks...
