    From what others have written here and elsewhere, it will be a high revving and peaky device. At that price, you'd expect it to be better made than the cheapest air cooleds though.

    castings look pretty decent. At least that's something.

    Those are for the liquid cooled Blata knock off pocketbikes, they do make good power but are on the peaky side. The genuine Blata engine these are copies of make about 15 to 16 hp.
    These engines are quite a bit smaller than a typical China Doll so they can go on a smaller frame or leave you with plenty enough room to add a jack shaft and CVT or shifter conversion so you can take advantage of the power they develope at high rpm. There were some pocketbikes that had a CVT that bolted up to the engine so if the bolt spacing is right and the clutch diameter is the same, that part would be easy.

    No problem.. I've been eyeing that same engine for a few months now because of it's nice power output... There used to be some youtubes for the liquid cooled Chinese pocketbikes and they can easily propel a 200 pound rider really fast... a LOT faster than I'd want to try on a bike that sits about a foot and a half high and weighs under 50lb soaking wet... Geared right these pocketbikes can hit 45 to 50mph easily, and the genuine Blata could do 60+ when geared for speed, these things used to dominate the pocketbike tracks but had to be geared down for a top speed around 25 to 30mph... power wheelies were the norm just by blipping the throttle out of the turns when geared down for small indoor tracks...
    here's a short clip of a couple Blatas playing on a kart track... not sure how fast they're reaching, but you can definitely tell when the engine goes on the pipe... These also look to be geared for a happy medium between speed and torque.

    Looks like a water-cooled CAG...
    I sure hope not...
    Never heard of a "Blata" before...but the vid is cool Davezilla!

    you're pretty much right about the water cooled CAG... they only made a small handful of them and they had around 6 to 8 hp, they were cheap but Fast.
    Blata is a company that put quality in the pocketbikes, a Blata Origami costed nearly 3 grand but it had a 40cc liquid cooled engine that put out 14hp, then they made a larger one called teh Blata Elite which made 16 hp from a 50cc engine. then the Chinese copied teh engines and offered water cooled Cag bikes for about a year or so back in 03/04 timeframe. they really didn't make a big hit on the market and by this time those bored politician's wives were hot and heavy about banning pocketbikes from all public roads, and the liquid cooled variation wasn't something you'd run out and buy for your 10 year old to put around on since it could easily push an adult well above the 50mph mark.
    The genuine Blata Origami and Elite series can easily push a 200 lb adult into the 60 mph range with 14 to 16 hp on tap and at 15000 rpm.

    i've looked for Blata engines online to try and get one for a mtorized bicycle project by connecting to a CVT and gearing it to go in the 45 to 50 mph range, but these engines are either not available or not cheap when found. A lot of the left over Blata engines were sold as RC boat engines because of their tiny size and ultra high output.

    Here's the specs on a Blata Elite 14WRS which is one of the strongest ones they make...

    You can get them as a full race version like this one either naked or with full fairings, and they also make detuned versions for younger riders as well as one simply called the 2.5 which meant 2.5hp air cooled, but very well built thruout.

    Bear with me here. How is the water cooled after taking up the heat of the motor?

    It's probably gravity circulation through a small radiator of some kind. A car heater matrix might do the job.

    Oh, so it would have some type of external radiator. Huh.
    Thanks.

    They do have water pumps, very small belt driven pumps, I remamber seeing spare belts for these on ebay back when the liquid cooled cag was more popular. You can stil find the replacement pumps and belts on some of the scooter parts sites.
