    How to make a go kart slower

    Hi everyone, I have a friend who just purchased a go kart for his 12 year old daughter. It's a little too fast for her. It has a 3.0 Predator engine. Is there a way to make it slower until she gets used to it? Thanx

    Upgrade Spark Plug

    So the NGK BP6ES with a .030 gap will work for a 212cc and 420cc engines?

    Upgrade Spark Plug

    I have a 412cc Predator engine on a mini bike frame and a 420cc Predator engine on a Go-Kart frame. I want to upgrade the spark plugs and read that the NGK BP6ES were highly recommended. If this is true, what size gap should it be or do these kind come pre-gapped out of the box? Thanx

    New Engine has no thrust

    lol yeah I agree! Even though it's pretty simple to look inside the filter, but who really checks for that when they're in the process of eagerly putting it together. All in all I think some good questions were asked for future repairs. Thanks again!

    New Engine has no thrust

    😳🙄😏😅Well I'm a little embarrassed, but I guess I got so excited while putting together the engine and bike kit, I overlooked one important thing. The packaging. Well, let this be a lesson. Sometimes the problem is not as complicated as you thought it was. The packaging for the filter kit I...

    New Engine has no thrust

    These are all good questions. I will go home and tinker with it and see what I can find. How do I find out the gear ratio?

    New Engine has no thrust

    OK what I can tell you is that I don't know that gear ratio or the OD of the rear tire. The gov is removed, stage one kit for the carb and jet, it has a torque converter and stock con-rod. Could it possibly be the jet?

    New Engine has no thrust

    It is a brand new engine and I've done the same to other engines that were new and never had this problem. I will check the gap on the spark plug and go from there, thanx

    New Engine has no thrust

    Unfortunately I can't post a video because it's making it too complicated. I can say that it does start right up, and then when I hold the throttle down it's sputters and a lot of smoke comes out of the exaust. I'm sure there's something wrong with the pistons. When I pull the spark plug it's...

    New Engine has no thrust

    Yes the throttle is hooked up correctly. I even manually moved the lever and it didn't make it difference. And yes that was the recommend it lash gaps. I did the same thing on my other Predator engine and did not have a problem.

    New Engine has no thrust

    Hi everyone, So my problem is this: I have a new to 212cc Predator engine on a Mega Moto mini bike. I removed the governor, replaced the stock lash spring's with 18lb ones, found top dead center and reset the lash valves. 5000th on the intake and 7000th on the exaust. So after everything was...

    Torque converter on Predator 420cc

    OK so I replaced the broken bearing. I rode it yesterday and everything seems to be working well. The bearing isn't loose or wobbly. I did a little research and ordered speed bearings. I haven't received them yet, but when I do I will use them and hopefully solve the problem.

    Torque converter on Predator 420cc

    I ordered the one that is on there now from Go Power Sports. It's the 40 series and says it works with 8hp-18hp. Should I go a size up to the 5/8"?

    Torque converter on Predator 420cc

    I just ordered high speed bearings and I hope that is the answer. I have yet to be able to ride this go cart consistently without something else breaking. I do have another torque converter plate by thats a different brand, but in order to use it I'll have to shift the engine to the side to fit...

    Torque converter on Predator 420cc

    What does it mean to have the clutch inboard? Hmmmm I've seen those but haven't bought them. I'm a bit frustrated cause I've had this same problem for a while and I can't fix it. Very discouraging
