[replyingto=scootnwinn]scootnwinn[/replyingto]Nice scooter! With a little regular maintenance it will last a long time, you can ride anywhere with confidence ;D

Bintelli is made by Znen, it's a Chinese scooter. There is plenty of information about Chinese scooters, and more specifically about Znen.

How much does the scooter cost? The logical thing to do is to compare the price with a "budget" Taiwanese model. No matter how they try to market Bintelli, it's still Chinese made with inferior quality metal. "Dressing it up" with Halogen bulbs, a Gates belt and a NGK spark plug isn't going to change that fact (a Taiwanese scooter will have that stuff anyway!). Neither is a warranty that requires the dealer to be involved in everything including oil changes. How much more is that gonna cost?

The last 6 scooters I've owned and ridden (3 Sym's, 1 Honda, 1 Yamaha, 1 CPI) all outlasted the warranty period without one issue, and never had a single problem as long as I owned any of them. If this track record doesn't convince someone to spend a few extra hundred dollars, then the world is further gone than I thought...

Kymco Agility 50 or 125
Lance Cali Classic 50 or 125 / Havana 50 or 125
Tomos Nitro 50 or 125
CPI Oliver City 50cc two-stroke

I checked online and saw the Bintelli Flash for $1299. The Taiwanese scooters I listed above range in price from $1499 to $1999. There is no reason in the world not to invest $200 more for a machine that's in an entirely different class as far as quality and durability are concerned.

Nice!

I believe the Benelli M50 is a two-stroke engine. If it suddenly stopped and then started again after a few minutes, it sounds like you had a soft seize. The engine overheated and the cylinder/piston/rings expanded until they seized up. After cooling down for a few minutes you were able to restart. You might have caused some damage to the piston rings and some scoring to the cylinder walls.

But I guess if you are going to install a BBK, these parts will be replaced anyway. Proper jetting is very critical for a two-stroke engine to prevent overheating, especially after a BBK is installed. Most people don't, but I would recommend adjusting the oil pump for more flow when upgrading to a BBK. You need to know that the Benelli brand is a Chinese made scooter, even though it is marketed as an upscale brand. Plain and simple the cylinder, piston, piston rings and cylinder head will be made of a lower quality metal that is softer and more prone to a soft seizure. Installing a quality BBK kit can help, but the engine casings and crankshaft will still be made out of inferior metal. The oil pump will be a cheapo without a way to adjust, but you can replace it with a much higher quality Mikuni that is adjustable. Or you can simply add an extra ounce of two-stroke oil to every full tank of fuel, but that's a pain.

These glorified Benelli M50's usually sell for $1500-$1600, I hope you got yours for a cheaper price. A Kymco Agility 125 is much higher quality, has more performance than a typical 72cc BBK two-stroke, and has much better fuel economy for $1800. The only advantage I can see for a 49cc is operating in one of the few states that don't require tags or insurance, but the usually have a moped speed cap of 30-35mph. I rode both a stock Yamaha C3 and a SYM DD50 legally unregistered in New Mexico, but I was always wary of getting a ticket because both would top out close to 45 mph.

It's not my intention to bash your Benelli M50, just letting you know what to expect. Good luck, I hope my info was helpful.

Looks just a bit lean to me. No signs of pre-ignition or excessive heat, but the porcelain is pretty white.

Remove the two bolts that attach the metal tube to the PAIR port on the engine. Rip everything off that is routed to the PAIR system. You will need to block off the line that was attached to the intake/airbox. You will also need to fashion a metal plate and then use the two original bolts to block off the PAIR port.

Rip off the charcoal canister attached to the gas tank vent line, get rid of any lines or hoses or secondary canisters attached. Sometimes these systems will have a vacuum line attached, it will have to be blocked off at the source. Make sure to leave some length to the gas tank vent line and reroute it to hang down out of the way.

Ultimately you want to be left with only the basic components.

fuel line from tank to fuel pump
vacuum line from intake manifold to fuel pump
fuel line from fuel pump to carb

also
carb vent tube
float bowl drain tube
fuel tank vent line

There should be a fuel filter on the fuel line from the tank. Some scooters/motorcycles have a vented gas cap and no fuel tank vent line.

Both Genuine and Lance (made by SYM) are very well made scooters, both with a reputation for reliability. You can't go wrong with either one. The Buddy 125 seems to have just a bit more zip, but has a smaller seat and slightly smaller chassis. The Lance Cali Classic 125 and Havana 125 have generous seats for accommodating a passenger, and a little more foot room on the floor board. Both have excellent warranties, but the Genuine's have a little better coverage.
If you do the proper oil changes and occasional valve adjustment, I doubt either will even need the warranty.

That being said, I think the $700 lower price of the Lance makes it a much better value.
