A go-kart’s horsepower directly impacts its speed, acceleration, and handling. Too much horsepower can cause all sorts of problems.

However if it's improperly installed, driven in abusive conditions (sand, steep terrain, excessive weight in the kart or rear tires taller than 15"), the clutch might only last 20 minutes. Go Karts with rear tires taller than 15" or an engine larger than 8hp require a torque converter.

It will handle up to 25hp 2 cycle engines and 16 hp 4 cycle engines. The drive clutch comes with either a 3/4" or a 1" bore. The driven clutch comes in either a 7-1/2" or a 8-1/2" diameter unit, the bore size can be either 3/4" or 1".

Used on 3 to 8 horsepower engines. 10 tooth clutches use #40, 41 and 420 chain. 11 tooth and 12 tooth clutches use #35 chain. Most installations use a 5/16-24 x 3/4" bolt, washer & lock washer. Grease the engine crankshaft and tapped hole for easy removal in the future.

Ratios do vary with wheel size, weight & other conditions, however you should keep your gear ratio at approx 6 to 1. Any ratio either smaller or larger will put too much torque through the clutch and cause it to slip, which will cause the clutch to overheat and the clutch will no longer function

While clutches engage earlier, they have a slip range at about 1,400 to 1,600 RPM. Slipping can cause increased heat and wear on the parts. However, once a clutch is fully engaged, it feels much snappier. This makes clutches more ideal for situations where you’re constantly engaging in higher speeds on the upper torque range.

A 7.9:1 ratio can only pull so much, and when you get to a hill, you have reach the balance between clutch slipping and the amount of horsepower that your engine puts out. A larger engine might help, but you might be suprised that you would end up with the same situation, a slippling clutch and no movement up the hill.
