Help with triton sr champ!!!

Okay so I have been out of karting for years and recently got a Triton champ kart. We run clone at 425 and track is a little under 1/4 mile dirt oval. Tires are ht3.we run at capital city in va, clay track with somewhat low banking and normally dry slick. Need help with setupnumbers and also gear ratio. Seemed to be a little slow to get off turn only turning 6300 at end of straightaway. Thanks
