Cool. Vento/BKM is MUCH better supported than Dazon. Dazon parts were IMPOSSIBLE.

Best of luck.

These are the guys that seem to have the most user info for Vento's. Mostly the bigger scooters though.

vento parts

not sure if the link will translate, but i found this: http://www.complex.com.mx/pedidosweb/IntermediaMain.Asp?pEncabezado=0&pPais=USA

looks like they should have everything she'll need. the entire crankshaft assy and piston for less than $150. i guess the next step will be the always fun exploratory surgery/diagnosis....

Re: vento parts

That's interesting. They don't list a Jazz, but it may share an engine with one of the others. I never looked for engine parts for Thelonious, so I didn't do interchange research. The bitch with Thelonious was just cleaning all the old two-smoke oil out and putting in the better stuff. Chow was the parts whore, and you can't find parts for it to save your life until you figure out what interchanges.

The people in New Jersey, where he was purchased, were really helpful getting the title stuff cleared up, so they may be able to point you in a good direction too.

Still not quite sure why it seized up. It wasn't a /scronk/ kind of seize, like piston wall scraping or anything, it was almost like a vaporlock kind of seizing. My suggestion as a start, would be to drain out all of the crank case oil, and refill it. I put a little gear oil in it(I've never changed it, since it only had a couple of hundred on it when I last worked on him), to see if it made the ugly rattly sound go away. It made it quieter, but didn't make it go away. Pulling the starter out, the ring gear was spinning freely, so I'm not TOTALLY convinced that's what was seized. I bumped the crank back and forth for a bit, and finally got it to turn, but it felt like it had a "compression drag" about it until it finished a few revolutions.

I was just doing an EMT kind of fix on him, since we didn't have time to tear him down to ALL the little parts, so that's about all I can tell you. The problem IS easy to reproduce, which is nice. Just gotta ride him until he's warm enough.

The cutout when he warms up is still the big problem in my mind. It feels electrical. He loses a tiny bit of power, and then just cuts. A new ECU is about $30(or at least, it was for the Dazon), and worth trying I think. A full run on the electronics to make sure there are no shorts or burnt wiring is another good one. I'd be tempted to wrap the ECU in some manner of waterproof box or balloon, since it's just out in the weather under the floorboards.
