Default Questions about golf cart with predator 420

Turning to the forums for help. I have a new predator 420 from harbor freight. First question. I get well over 5,000 rpms with the gov still installed. I have read that it is limited to 3600 but other places I read 5500. What is right? Question 2. I have a comet 780 clutch setup and 18 inch tires. Iím getting 19 mph at 5200 rpmís. Should I be getting more?

Thanks in advance.

The governed rpm is 3600 rpms. At 5500 rpms the stock connecting rod will not last. I am also wondering why with stock valve springs why you are not getting valve float before hitting that rpm. You don't say which cart you have. The gearing of the different carts affects the top speed.

Good point. I have a Hyundai cart. I put spacers in the driven gear to make it fit a 1 3/16 belt. What I donít understand about the govonor is if it is limited at 3600 why will it go up to 5500? When I hit the gov in my car thatís it. I canít go past it.

Are you sure you have the tach on the right setting? The clones fire every revolution like a 2 stroke engine. One firing is just wasted.

I just checked. Itís a pulse tac for small engines. Also am idling at 1450 rpmís so it seems right. I ended up backing out the screw in stop on the throttle. I can get it under to 5700 rpmís no issue problem. And itís screaming so I think itís reading right.

I am surprised you haven't dropped a valve. That is usually the first area that needs attention to run that kind of RPMS on a clone. HD valve springs and beefier push rods take care of that. Next up is the connecting rod.
