Either air filter is too clogged, and/or carb is running too rich.

Adding the air box restricts the air flow a little, causing the carb to run richer than without it.

Boggs out with acceleration.

Hi Suzanne, a common fault with automatic scooters is the transmission or clutch. Your scooter has a centrifugal clutch which contains rollers, these rollers tend to wear flat over a period of time. You would need to remove the outer left side engine cover and the 'front' clutch to inspect the rollers. Unless you have an air ratchet gun to remove the crankshaft nut i would bring it to a dealer. Rollers are about 20 euros and the job shouldn't take more than a half hour, once they have your scoot on the ramp! Also check the condition of the air-box itself, make sure its not cracked/broken and connected properly to the carb, with an air filter fitted. Scooters make so little power that any change or variation in this area can seriously upset the fueling. Lastly check your spark plug and gap, must be clean and gap no bigger than 0.07-0.08mm. Best of luck..

Scooter runs but bogs down when given throttle 2007 triton vento scooter will run bogs down when given throttle

Make sure the air box is installed and the snorkel is on the air box and that it's in good condition. They don't run well or sometimes at all beyond idle without the air box. Could also be a clogged main jet or otherwise dirty carburetor.

Neither Jeff, I believe you will extract more top end from the scoot by removing the belt pulley restrictor and I also believe that the exhaust pipe is restricted at thesilencerend

What can I use as a pet crate, to keep my dog in at night?

The cheapest and most comfortable thing for your dog isprobably a large cardboard box with holes in it. Make sure there are ample holes so that itgets enough air. I would also weight thebox down with something heavy so that the dog can't scoot it across the floor.

Bogs down & spits back through carb.

Sounds like you may need a valve job. Have you been keeping the valve clearances adjusted? It's important to do that on a four-stroke engine. Check your compression to find out if the valves are ok.

Starts good, idles good but bogs down when accelerating.

its the caburtor, it blocks the fuel from the pump and it also bogs out, factory fault you need to replace the caburator and bypass all the smog stuff, just install the o2 sensor into the air intak hose thats what i did
