Go Kart Maintenance Tips and Tricks

Go karts need to be maintained and repaired, just like a car. With regular maintenance, your kart will last a long time. Without proper care, it may end up in the trash heap, rotting away in the back yard, or become unsafe.

Below is a list of links to go kart parts that need to be maintained, or repaired when damaged.

  1. I’ve got a predator 420 and I got a 30 series torque converter and with in 5 mins the belt rolled over and burnt up…is this torque converter to small or did I install wrong…I’m having some trouble with this… obviously something is wrong but not to sure I want to keep buying belts every time I ride it. Any advice would be great

    1. TJ, the 420 predator is about 13-15 hp. The 30 series is only rated up to 8 hp. That is why you are burning up belts. Go ahead and get a 40 series torque converter and your belt problems will go away.

  2. Thanks for the list of parts to maintain. I am getting a new go-kart, and I want to make sure I know how to care for it. I didn’t realize that you need to remove and install new bearings regularly. I will make sure I learn a little bit about the bearings and stay on top of the process.

  3. Hello Kartfab,
    Great site & info for a newbie. I bought a used kart, it runs ok for a couple of passes and then bogs down, no low end torque. I cleaned the carb thoroughly and found out the main jet is .040, is this too big? The engine is a 6.5 clone, after market air filter, header, no governer, 18 lb springs, supposedly a gx160 head. The head, valves had a lot of carbon build up, which I cleaned. I put in a .036 main jet, it runs better but still no low end torque. Any ideas other than buying a predatorengine.

    1. no low end torque could be due to a number of reasons. Since the kart is heavily modified ill just give you a few possibilities 1)excessive porting reduced intake and exhaust velocity. High air velocity is extremely important for torque 2) camshaft is built for high rpms (which ruins torque). 3) timing is too far advanced (advancing the timing shifts the torque curve up to higher rpms, which ruins torque at the low end 3) valve sealing may be poor 4) cylinder sealing my be poor 5) exhaust header may be too large (may also be compounded by porting the ehxuast port too large 6) improper gearing: this one has nothing to do with your engine, rather your gear ratio, and tire size. An ideal gear ratio would put your go kart at 25 mph at 3600 rpms for a centrifugal clutch, and up to 35 mph at 3600 rpm with a torque converter. 7) carb venturi size could be too large (bored out too large) which also reduces low end torque due to the low intake velocity. If the carb jet was really bored out that high, it could be because the carb venturi was too big, and an excessively large jet would have to compensate for the lower flow to get a good fuel signal. Hope that helps. Also, the jetting on a 6.5 clone with aftermarket modifications like that should be between a .033 to .038 typically.

  4. My son races jr jr class predator motor. The rules are factory condition red restrict or plate and restricted to 3800 rpm and 4.5 gear ratio. What can I do to increase the top end. He is steady 3rd and two other carts just seam to walk away from him.

    1. not sure about the rest of the rules, but you could look into modifying bore, stroke, compression, and headwork. There are a lot of tricks, but id say stick with the rules, and work on the stuff you can modify.

  5. Gg, thanks kartfab for the list now I can make a go kart (even I’m 9yrs. old)

    🙂

  6. Okay guys I have a tomberlin foxfire 620, That I bought from friend to help him out. I’m relatively new to go karts , so I don’t know too much. My problem is somewhere along the karts lifespan changed the driver side front spindle to some crazy one lol. I need to know if anyone can point me towards the size I need or a good price on the replacement the cheapest I’ve found after searching for hours is $144 for one so way too steep. I need help! Please!

  7. I have a go kart like MIDAS but with a 212 predator, it has a 9T jack shaft sprocket and a 54 tooth sprocket that needs to be replaced, which size sprocket would be good with the 9T speed-wise?

    1. put a carb used on a smaller engine with similiar displacement on it. Yes governor works with carb so obviously it needs to go. Understand there are risks associated with governor removal as well.

      1. I have a kart with a 99 cc predator engine. I bought a new 212 cc to replace it. The new one doesn’t seem to fit. The fly wheel seems like it’s in the way. What do I need to do? Shouldn’t it fit? And will I need any other parts to make it hook up?

  8. I built a Predator 212 for performance and i need a 12v charging sys for efi. Im using an Arc billet flywheel #6625 and the stock coil right now. The efi will be added soon, so i need to figure out how to charge the battery but i dont know what will work. Can you help?

    1. You need to know how many amps your efi system needs. Mist charge could only provide 3, so you may be sol. Try a pulley/alternator instead, but that creates more drag too.

  9. What kind of grease or oil should you use on the crankshaft of a predator 212cc. Or more so onto the bearing around the shaft?

    1. Possible, but NOT SAFE. Please don’t die. So if you end up doing this, I don’t want to see you in the obituary. Just so you know, the deluxe go kart kit motor mount will accept the 670 with no modifications, and the website that sells the go kart kit even sells the 40 series bolt on torque converter so good luck. I am in no way responsible for what you do with this information so please please just don’t do it if at all possible. Why not try the predator 420cc? That will be loads of fun and you are less likely to get hurt. I drive a go kart with a honda GX390, which is a little less powerful than the predator 420, and it has all the power I need.

  10. Hi,

    I am rebuilding an old Manco 2 seat go kart. I only got a rusty frame an had to get all the parts for it and figure out how to put it together. Your website helped me a great deal figuring out how it all goes together. I am in the process of painting it and then we will see how it turns out.

    Thanks a lot for all the great pictures, instructions and videos!

    Chris
