Not for high RPM applications but SHE RIPS
I installed this on my 9k rpm, 14hp, 57mph, 212 ghost powered shopping kart and in the first test run the belt had over extended and flipped, locking it up. After we decided to not go that route, I installed it on a mostly stock (gov delete) 212 swapped old Honda 110 dirt bike. She rips, drove it 30 miles in one day and didnโt run into any issues! Excellent for the price. Very smooth operation. Makes my dirt bike do rooster tails.

Great Value. Be careful not to lose the little brass bushing on the clutch; once it's gone its gone
arrived quickly, Took some time to line everything up. It's helpful to have washers to accomplish this. Fit your chain only after you are sure the belt tension is correct. Somehow I lost the bushing that allows the belt to glide over the engine clutch when moving the go Kart. My fault. Torque converter works great. Would buy again.

incorrect measurements and excessive shipping times
purchased 4/2026 keyway is still manufactured wrong it is pretty deep and you need a thick file so it doesnt bend and not get the middle. took literally 2 hours for me to get it very close, had to beat it on which means it will be terrible to get off in 5 years. had to edit review due to amazon censorship of the truth. So I had a LONG WAIT for my pizza. the PIZZA SHOP took forever to get my PIZZA to me.

Hole to small for fitment.
I would give this a 5 star but the problem I had is the hole for the driven clutch was to small. Luckily I own a port and polish kit for cylinder heads and used that to hone out the hole to fit the shaft. If I didn't own that kit and didn't have the knowledge of machining I would have had to return this item. Other then that it does exactly what I need it to do.
