What Engine and sprockets

[r_chez_08]

Hi
i am new to karting and wondered what size sprockets i would need to get my partually built kart going about 25mph.
it has 10" wheels, and i was thinking about getting a honda gx160 5.5hp engine. the kart is going to be used on farm tracks.
also, would the engine be good enough.(i am not likely to mod it)

If you put a torque converter on it, it should be fine however i dont know anything about sprocket sizes.

If you run 10" wheels and # 40 chain (or #41) you can easily run a 48t on the rear wheel and a 10t clutch and get nice results. If you run a #35 chain, a 60t in back and a 12t clutch will get you VERY close to 25 mph, with the stock 5.5hp giving you decent acceleration.
If you're going to keep it all stock, do you have access to the Harbor Freight 6.5hp motor? Probably a LOT less expensive than the Honda. Besides making sure the air filter doesn't leak, the Harbor Freight 6.5's are very good motors, stock.
