    Well scooter is still alive and well. I have had to clean the pilot jet out again. This scooter hates ethanol with a passion. It must be run weekly. I kinda need a rear wheel but they are asking too much on eBay. Just riding it a bit bent. Railroad tracks did it in.

    My Helix is the same way. I had to start putting stabil Ethanol treatment in it and that was with a Honda Shop Rebuilt carb. My China Big Rucklone hasn't had a issue yet with it but when I started using it in the Helix I started using it in the Rucklone.

    I have a 5 gallon gas jug that I measure the Stabil Ethanol into it and fill it with mid grade. That way it always is ready to go and metered out for both bikes.

    Give Brent at Fenton Power Sports and see if he has a rear wheel for you. He usually has great prices. He is closed until the 6th of Feb though for some downtime. http://www.fentonpowersports.com/

    Thanks. I will go the stabil route too. The ethanol has killed 1 weedeater and 1 lawnmower already.

    My 2008 Chinese 250 scoot has never had clogged jet issues, if anything little carb-icing in the colder months.
    Once I get engine started, I keep the throttle open slightly for 15-20 sec, the engine stays idle as it should.
    13,460 mi. on it so far, never had to clean the jets.

    Make sure it is the Stabil Ethanol treatment. It is greenish blue. The traditional Stabil hasn't worked with the new ethanol fuels for me.

    Nice to hear the Chinese scooter is still running. I am seriously considering getting one, though it would be a newer model. There is a place here called Performance Scooter that still sells them for around $900 assembled and ready to go. I'd just like to see how long I can keep it going. I not only don't mind working on things, I actually like to. I am a perfectionist, and can usually find a way to improve almost anything. Chinese scooters are definitely better now than they were 10-12 years ago, when I had a part time job on Saturdays uncrating and setting them up for a local shop. They were mostly Tank brand, and were literally falling apart in the crate. There was almost always broken pieces of plastic and aluminum, and a few bolts and screws on the bottom of the crate. I don't think I ever saw one that did not have cracks in the bodywork. Everywhere a screw went into plastic was cracked.

    Chinese scooters are not the same as most bikes from the '50s and '60s. Many of them, including Harley and British bikes were unreliable, but they were made out of pretty decent metal. The Chinese seem to use some kind of what is commonly known as "pot metal" It is very soft, threads strip out easily, and it also cracks easily. Also their welds are TERRIBLE. I could do better, though I suppose it is not easy to weld that thin soft metal without burning it through.

    Somebody mentioned the Kymco Super 8, which looks a lot like a Chinese scooter, but is much higher quality. I think it is a great deal for $2500. Unfortunately, though it is called a 150, it is technically not freeway legal here, as it's actual displacement is only 149cc. It would be just my luck to get stopped by a cop that would bust me for that one lousy cc.

    About the oil, DEFINITELY change it every 1000 miles. These small engines don't hold hardly any oil to begin with, and it gets dirty fast. And use 20w50 if it is hot, like it is here in Phoenix in the summer (115 degrees plus, and that is measured in the shade) I have a Zuma 125, a Vino 125, an XT225, and recently had a Rebel 250. I always change the oil in these small bikes every 1000 miles, but I use standard non synthetic Castrol GTX car oil. So far so good, the Vino just passed 25,000 miles and still runs like new. I'm expecting it to make it past 50,000 miles. I just put the third belt on it.Valves have been adjusted once. It eats rear tires, but I'm on the heavy side and always carry stuff with me, so that is really kind of expected. Those little 10" tires turn fast. I don't ride it much since getting the Zuma.


    Ethanol is BAD for ALL engines. Unfortunately is is all there is in this nazi state. Unless you want to get racing fuel or avgas, and that won't work on trips. I found the "marine" grade Stabil works fairly well, it's what I have in my XT225, which only gets ridden every few weeks, though I do start it up, warm it up, and ride it a mile or so once a week to prevent deterioration.


    Anyway, thanks for all the information. If I get one of these things, I will do everything listed here and probably a few other things as well.

    Some interesting "won't turn off" videos related to this model . . a continuity issue with a jumper in a connector plug (perhaps for an optional alarm system).

    In the context of engine displacement, Dongfang is offering some 168.9cc models . . which appear to be GY6-B 2-bolt valve cover engines with DC-CDI ignition systems. GY6-B engine part resources include ScrappyDog and PartsForScooters.

    Personally I am not interested unless it is Jap big 4 manufacturers, kymco or Sym or a Piaggio group product.

    Life is just too short too put up with crap quality and the attendant headaches

    The quality of the china scoots is appalling how else can they make it ship it around the world and sell for $899 it has to be junk quality

    All of my carbed bikes are like that. The small amount of fuel in the float bowl separates, the gasoline evaporates, and only the ethanol is left. Corrosion starts almost immediately, and the problem with corrosion is it does not stop unless you remove all of it which requires carb removal and cleaning. Carb cleaners are designed for organic residue, like what is left behind by actual gas.

    Both the fuel pump and fuel level float on EFI Royal Enfield motorcycles have been found to be susceptible to ethanol damage. The plastic float and plastic parts in the fuel pump melt.

    I also wonder if that might be the source of the problem Yamaha keeps having with their fuel pumps.

    This stuff is what I use in Methanol burning sprint cars, it ROCKS,
    only stuff I've ever seen that allows me to leave methanol in the system
    more than a day or so without having massive issues.

    FYI Hillborn style injection fouls OVERNIGHT if methanol is left in there..
    We usually suck the methanol out and fill with light oil or regular race gas to protect the injection parts. The methanol turns into the same white chalky crap you find in your carbs when you tear them down..

    It does not take much, especially for fuel systems on bike size engines..

    I bought my wife a Vento Phantom 150cc CVT about 8 years ago. Pretty much exactly like the bike pictured in the first couple of post. $1800 delivered. Could not get one of the cheaper ones due to CARB regulations. Yeh fucken California!! Put it together and it would not start; nothing. Found a pinched hot wire to the frame which grounded and shorted everything out. Fixed. After the first ride I noticed the gearbox starting to leak. Gasket had a kink in it. Made a new one. Changed the gear oil, good to go. Finally it kind of ran like pooop, I live a 6250'. Pulled some foam out of the airbox to increase the air flow. Easy carb tuning. From that day on the scoot ran flawlessly for 3.5 years. Winter maintenance involved throwing a tarp over it and letting it get covered with snow. Come spring crank it for 10 seconds and she came to life. Didn't pull the battery, didn't drain the gas, didn't even put gas stabilizer in it. Sold it to a chick (professional Skier) that broke her leg and couldn't ride her bicycle that summer. See it around town some times still ridden by some other guy (assume she sold it).

    Great scoot IMO.

    I am familiar with Hilborn injection. It is one type of FI I don't have a problem with. No experience with methanol, but I have repeatedly found carb damage from ethanol. I have found rubber and plastic melted, steel rusted, and brass and aluminum corroded. It HAS to be ethanol, gasoline does not cause that kind of damage.

    Usually it is not the alcohol, but the moisture that the alcohol absorbs. Alcohol is hygroscopic, it will absorb moisture from the air, as much as it can until it saturates and separates.

    Pretty Sure that is the ZNEN factory.

    My Retired Aunt in law that still does some corporate environmental safety studies, has visited that plant and a few others a few times. She holds ZNEN CfMOTO Loncin and Zongshen in very high regard Compared to the several "Slap em together" factories she toured.

    They really need to start wearing safety glasses. Hell they make them all in China anyway.

    Ok I can't resist.
    Why would they bother wearing safety glasses that were made in china........
    Oxymoron.
