VEVOR Primary Drive Clutch, 780 Series Go-Kart Drive Clutch 1" Bore 1/4" Keyway Comet, for Taking a 1 3/16-1 1/4" Wide Belt 4 Cycle Engines, Replace# 302405A / 302405

Installed on predator 420. Works great.

Works as expected on my Duromax 440 but be prepared to also purchase different weights and springs because this clutch will engage on idle with even slightly modified engines.

Works good

Works as described

Well for starters it's big and needs spacers it comes with no instructions on how to install properly if you put it on a 420cc predator engine it still engages while in idle meaning it will try to pull off without you pressing the gas you would to lower the idle all the way and put your brakes on to prevent it from taking off maybe change the jets on your carburetor try to get the. Rpms low as i possible. I put mine in a yamaha g22 electric golf cart to convert it to gas so you may have better luck then me it's still better then the 40 series clutch Chinese knock off that one got stuck open on me soon as I got it out the box I hope this review helps somebody.

The clutch kits in at a lower speed than my motor can idle on a predator 420

It looks like a decent 780 clone but mine trys to engage at idle, just to the point where I can use but also at the point that belt wear will get bad soon

Noisy and poor quality
