Since it forms inside a plastic container/tank, seems unlikely that it's aluminum oxide, though it does look like that. Doing some reading, there is apparently some kind of emulsifier being added to fuel that results in this. Sent from my Moto G (4) using Tapatalk

Been seeing a lot of grey powdery stuff plugging things up this year. Instead of varnish, gas evaporates and leaves this stuff behind coating the tank. New gas breaks it up and it likes to settle in the bowl. Apparently it won't actually dissolve, and it's heavy enough that it will settle...

BOR Motor Sports in Houston seems to be able to order parts for these things. Look on Craigslist and see if you have a local dealer. Also you can order from dongfang out of California I think. Just download a parts diagram from dongfang. You might be able to switch to an aftermarket axle...

What's holding those rear wheels on? I don't see an axle in there. I take it that's the Ninja engine sitting in there. Does it need a lot more work to get it mounted and connected? That would be an awesome amount of power. Maybe use a jackshaft to get even more reduction. I'm thinking a...

I watched a couple of YouTube videos of a guy mounting a predator 420 on one of these. It required removing the cage around the stock motor, putting in a new live axle and adding a piece of box tubing to create support for the engine mounting plate. What do you want to know about the carb...

Turns out that hole does not allow dirt/water into the oil. Despite the manual, there is only one oil compartment for the crankcase and transmission. I spoke to a guy at a local dealership that sells a lot of these Chinese buggy things. The carb bowl is actually not riveted, but has screws...

I know very little about the motor and carb. I do know that carb bowl is riveted on making it difficult to clean properly. I learned that the mixture screw is key to making it run and idle properly without using the choke all the time. The 110cc version I'm working on seems to run well now...

Does the factory motor run? It may not be a torque monster, but the HP rating isn't that bad. It revs high which is kind of a plus in my opinion. Silly accessories aside, real suspension and 4 wheel disk brakes is nice. I'm messing with one for a neighbor and after getting the carb...

I got it running now, I'm guessing they worked on it themselves first. Mixture screw backed out wayyyyyy too far. They had it about 1 3/4 turns out. It needs to be more like 3/4. I cleaned the carb as best I could, they can drill their own rivets out. It runs pretty good now. I connected...

Definitely not a 2-stroke. I was able to get it running today. Took the carb off and cleaned it out as best I could. The bowl is riveted on so no getting in there. It idles great with the choke on, but will not take fuel when you try to accelerate. Won't idle when warm and choke is off, but...

Is there a low oil shut-off on these things? Oil is right at the bottom of the zone, I'll top it off when I pick some up. My neighbor conned me into looking at her son's kart/buggy/whatever. I haven't had a chance to do much yet, but a shot of starting fluid down the carb didn't result in...

Without knowing the frequency of the pulses, I'm not doing a lot more than guessing, but I'd say that you might need 20 or 30 thousand microfarads of capacitance. Again, a battery may be a better choice in your case since the smoothed voltage may not even be high enough to give any light at all...

Do you know how much current those LED lights draw? You may need to use much more capacitance to get good results. At some point, the battery is likely a better way to go, especially if you want lights when the engine isn't running. 13V is on the low end of typical battery charger output and...

You could try installing a capacitor. It will smooth out the pulses and if the average voltage is enough to turn on the LEDs, they will glow at idle. If it's not high enough, then they will likely just stay off. At any rate, it should smooth out the pulses. Find out what kind of voltages you...

That's because it was cast. They should have machined it out of a billet. ;)
