    I figured it would be faster, I never ran a gear box on the old racing kart….this was in 1999 however, built Briggs 5hp (methanol) with racing clutch and fairly decent size sprocket (I don’t remember specifics since I was 13) and it would run around 57 on the dirt circle in the straights. These stock engine karts look like so much fun though, brings back so many memories. Love the builds, your content has motivated me to get my daughter into racing karts.

    I finally got everything together with my lifan 125cc with 4 gears. 17teeth up front and 25 rear, I was able to top out at 46mph. that 4th gear really helps

    This is gold! I'm building a dirt kart for my lad with what looks like the same Lifan engine. I was wondering about sprocket ratios and this is a big help. All else being equal, if I run 14/44 that should drop the top speed to about 50 km/hr and give good acceleration. Thanks!

    also i think you should weld some tubing to the gear shifter at an angle to make it easier to shift. if you did make it rise up about 3 or 4 inches from where the shifter is now

  • @christopheryniguez825
    @christopheryniguez825 7 років тому +22

    I know this may not make sense but you actually need to put a larger sprocket on the rear axle. Yes a smaller sprocket would make a kart or bike go faster in theory but only it has enough torque to pull a smaller gear. You engine only sounded like it was to about 4500RPM's or less. Essentially it wasn't going to redline RPM's because you didn't have enough torque to pull a rear smaller gear. Make your gear ratio about 3:1 and play around with gearing a bit. Ultimately you want to be able to reach redline and near max RPM's so that you utilize all the HP and Torque. I gurantee you will get 5 MPH or faster with a larger rear sprocket, revving the engines full RPMs. You could also run twin engines on the CVT(torque converter), single gear, go kart. I just made another motor mount on my kart and hooked it up to the drive shaft. I hit about 75MPH, with two highly modified predator 212cc engines.

    • @luvstruck2733
      @luvstruck2733 7 років тому +3

      Yes, this man speaks the truth. I'll give an example. A small engine can only pull so much weight. If you put a very large sprocket on the back, the engine should be able to reach it's maximum potential. Too large and will accelerate more quickly, but will not go very fast. Too small and it will take forever to reach top speed, if it has the power to get there. This seems to be the situation you are in right now. There should be a horsepower rating for your engine when new. Since you are starting out with a used engine, a bigger rear sprocket is going to be a necessity. Ask your local go cart place to suggest the proper sprocket for your application. The ratio can be found by counting the teeth on each sprocket, and dividing the numbers. The wheel size also makes a difference. It's easy to learn, and makes all the difference in the world. A jack shaft can also change the ratio, but they cost money, and it robs power. The quickest, easiest, and least expensive solution, is going to be the larger rear sprocket.

    Use a bigger carb to let it rev out more . Use an rpm gauge to set your sprockets right fir more speed

  • @microsoftservice3835
    @microsoftservice3835 6 років тому +7

    Well on go karts is hard to get 125cc true top speed, because of the small wheels. 36mph is decent...my daily moped 125cc 4 gears, small carb, 17" wheels, max 7500rpm, 15-36 pulley it can do 71mph and haha it can do more when the cyl.head is ported 100%, big carb, body weight plays a role too...btw your go kart is nice

    • @microsoftservice3835
      @microsoftservice3835 6 років тому

      Balabay you should play more with different sprocket numbers and see what your sweet spot is, for everyone is different

    • @nickkluger97
      @nickkluger97 5 років тому

      Impressive, but I bet it takes a long time to get there. Porting the head isn't going to give you big HP increase, probably half a hp on the top end. The heads on those little 125 motors actually breathe pretty well stock, I would just clean up the ports. However if you did port it I would definitely suggest boring it out and going for a more race-oriented cam. Nothing too radical, just more lift a longer duration. And definitely go for a bigger carb, but too big and you wont be gaining anything.

    Because it's a pit bike motor first thing is swap the stock CDI for a performance one which will change the ignition timing and increases and or removes the max redline. I did the swap on my on pit bike and I got 6mph higher top speed without changing gearing.

    have a 212cc predator and have removed governor we have redlined the thing daily for 6 years and never had an issue havent even serviced it since we brought it in 2011 everyday it does around 2 hours drift trike hirage and is on limiter the whole time. Smokes blue smoke now as expected with the thrashing its had and no servicing and still loves to be valve bounced

      It's nice to know that these engines can take a beating. Besides governor removal have you done anything else to your engine to improve performance? Have you messed with your carb or installed any other components on your engine?

  • @anthonyshoemake4739

  • @_Bonez12
    @_Bonez12 7 років тому +1

    I'd say try jetting the carb for more fuel and try raising the tire pressure to lower rolling resistance. This is just something to try before tearing the engine down for serious mods.

    • @balabay77
      @balabay77  7 років тому

      i always thought that bigger rear sprocket will give you lots of torque but not the top speed. i had 37 tooth sprocket and it gave me 30mph but with new 21 tooth sprocket it maxed out at 36.

    change front sprocket to a smaller one. maybe a big bore kit would work too or even nitrous. just a general upgrade of all parts e.g. exhaust, intake and carby to a proper branded version not a cheaper version aways helps

      He needs a smaller rear axel sprocket or larger engine sprocket to increase top speeds. Smaller engine sprockets will increase acceleration.

    Nice kart! What size axle sprocket is that? #40,41 or 420? The ones on ebay seem to only be #40.

    • @balabay77
      @balabay77  7 років тому +1

      Yes sir its #40 sprocket. I already had #40 chain so i got the cheapest sprocket i could find. For some reason other sprockets we much more expensive than the one i got. I think there was a sprocket for #35 chain but i wanted 40 instead. Thanks for watching.

    • @PyroGuyz95
      @PyroGuyz95 7 років тому

      balabay77 Thanks for responding! But one more question, did you have to swap the front engine sprocket to a #40? if so, do you have a link to that part? I can't seem to find it. I am trying to use this setup on my drift trike to hopefully gain some more top end speed. Thanks

    • @balabay77
      @balabay77  7 років тому +1

      I used 15 tooth for #420 chain sprocket and it works out great. 420 and #40 got the same pitch but 420 sprocket is slightly thinner than 40. My local store that sells Chinese atvs offer 420 engine sprockets for $10 but i usually buy them on eBay for around $5 or so.

    • @PyroGuyz95
      @PyroGuyz95 7 років тому

      balabay77 Thanks for the help! I was running a 17tooth front and 40t rear getting to about 37mph with 4 gears. Hopefully with your setup I can go 40 or even higher. Thanks again.

    • @balabay77
      @balabay77  7 років тому +1

      Sure thing buddy. Let me know how it goes.
      My previous rear sprocket was 37 tooth and it was topping out at 30. Now with 21 tooth its top speed is 36. So smaller rear sprocket does make it go faster.

    @luvstruck2733 7 років тому +40

    What kind of 125 cc three speed with reverse? Also your engine sounds bogged down. There are several improvements that can be made with little or no money. All engines are air pumps, so the more unrestricted air flow it has, the better it will run. First thing most people do is replace the air cleaner with a racing air filter because of less restriction. Next would be to replace the muffler with a header. Both of those open it up a little and let it breathe. Next, disconnect the govenor so you can get more r.p.m.s. After that it begins to get a little more technical. You can remove 10 thousandths, or so off the head to get higher compression. 10 thousandths is just an example. Each engine is different. Then when you can tell it's running a lot better re-jet the carburetor to a larger size, or buy a bigger jet. Go to a colder spark plug, or whatever works by those already going faster by doing what you are trying to do. All these ideas are inexpensive, and can be done at home depending on your level of experience. Hey, we all have to start somewhere.

      Luvstruck the motor has a pod filter and aftermarket exhaust. this motor has cdi ignition not mechanical so no gov to remove and despite what people know these motors cdis do not have a rpm limit in them. what he can do since the stock 19mm carb is maxed from the get is swap to a 27mm as u said more air plus more fuel. addition adding inner rotor kit will allow it rev higher. porting the intake and exhaust will help also 'gasket match'. further more these are lifan motors the make from 49cc to 140cc then switch to vertical for 150 to 250cc. cheap and easily found parts.

    Мне нужен твой opinion. Какой двигатель сильнее 125cc или Honda with torque converter?
    У меня есть Honda 8hp но я хочу купить 125cc, мне кажется что они лучше так как они с трансмиссией идут. Какой движок вам нравиться больше? Какой из них делает burnouts better?

      To be honest with you I'm not an expert when it comes to engines. From personal observation horizontal shaft engines are (for the most part) reliable and easy to use. They can be modified to produce more HP and they can hit top speeds well over any 125cc engines with the right setup. As far as 125cc engines go, try to get Lefan if you can because other engines are just a knock off copy and not as reliable I guess. Another hurdle with these engines can be figuring out how to set up your clutch if you get a manual engine. My engine is semi-auto so there's no clutch pedal needed. They both can do burnouts depending on persons weight. Obviously a kid is more likely to do a burnout than adult. All in all, they both have their pluses and minuses but I'm leaning towards horizontal shaft engines because they are cheap and disposable especially HarborFreight engines. Use them, abuse them, and swap them for the next engine.

    The most performance improvements are possible through improving your carburetor. Seems like its running too rich from the video, leaning it down to a better air:fuel ratio will give you a LOT more power.

    • @balabay77

    they sell alot of stuff for the 125cc. the cheapest thing that might add a little speed is a cdi. other than that you could buy a cam, or big bore kit. now that you made that engine mount you can use any of those style engines... the ones with clutches make good power. lifan 125cc big valve engine is less than $350. you can go as high as 200cc direct bolt in

    • @balabay77
      @balabay77  7 років тому

      My best bet would be a 2 stroke. Too bad that they cost too much even used engines are pricey. If i ever come across a cheap 2 stroke than maybe i will build another kart. Thanks for your advice and appreciate you watching.

    • @vtecbanger3180
      @vtecbanger3180 7 років тому

      Yea cdi does add a little pep and they are affordable. I feel the same way about a 2 stroke. I've built a gx200 clone with all the bells and whistles, and own a lifan 125cc big valve 4 speed. I'm happy with both. I'm going to try a 13hp techumseh after winter in a small buggy I have. I have done alot trial and error with this things and have yet to hit 60mph lol

    • @rogeroconnor5182

    if you want more power. try looking into salvaged motorcycles. Their are a shit ton of them, and you can get them cheap. i would recommend junkyards or online salvage auctions like copart.com you would be looking at anywhere between 250$ up to 1K. But at then end it would be worth it having an Yamaha R1 or a Yamaha R6 motor. This is also another way to make money, Because the parts that you don't need of off the motorcycle you can sell on craigslist or your local classifieds. I would you take a look into it. Would make a mean go-kart.

      I totally understand that it would be ideal way to make a sick go kart but my issue is the kart would be too heavy to lift inside a van or roll it in a truck bed.
