Assuming the clutch can take the strain of a 5:1 ratio, yes.

Race karts tend to have smallish tires, but are also designed to run on flat, hard surfaces. If that be the case, you'll probably do OK. If you're looking to use it as a yard kart, you might need to regear.

The type of clutch you're running will make a big difference too. A disc type racing clutch with a relatively high engagement would be appropriate for that setup instead of a plain old centrifugal.
