The speed of a go-kart with a 12 hp engine can vary based on several factors, including the weight of the go-kart, the gearing, and the type of terrain. Generally, a 12 hp go-kart can reach speeds of around 30 to 50 mph (48 to 80 km/h). However, modifications and specific designs can influence these speeds significantly.
Max Speed 37-39 mph... that's pretty fast for a go-cart.
fast as it needs to be.

Dude it is an econobox not a racecar. Stickers and a shopping cart handle don't make it fast. About as fast as a shopping cart can go downhill
up to 40 mph
about 60 to 80 mph
About 10 to 12 on plane
It would depend on the gear ratio.
25 if thers to people in the go cart and if thers only one person in the g cart then it will go 30 to 40 mph
with a good sentrifical clutch about 40 to 50mph
60mph-70mph top speed
25-40
