Can you help with my Vento Triton R4 scooter starting problem?

by Brian Adams

I own a 2004 Vento Triton R4 Scooter, that started once and now won't restart. It sat outside all winter, with about 1/4 tank of gas. About 2 weeks ago, I put some HEET in it, filled up the tank, and got it started.

Now, with a full tank, I have been trying to get it started all day without any luck. The battery is now dead, and I have been kicking it all day.

My dad suggested using some ether, but to be honest, I am not sure if that would help. Any suggestions/things you think I should check? Any help would be great!

by: Mark

Spray little starting fluid in carb if it starts off that and dies give carburetor a really thorough clean out majority of the time the pilot jet and the main jet holes get clogged up especially having gas sitting for a while I just did this to my urban r4 scooter as it sat outside for 2 years I no have it starting on it own nicely. After what I mentioned.

Hard to start the engine, starter & spark plug are good NEW
by: ATG

If your beloved Vento Triton R4 won't start the engine.

Here is what to look for...
1. Battery must be 12VDC or higher.
If you have no scooter battery, use your car
2. Look under the gas tank, you will see the
ATG Petcock. The ATG Petcock has a 21mm
Brass Bolt with two output tips.
Remove the top black rubber hose from
ATG Petcock to Fuel Filter.
Remove hose at the input of the fuel filter.
3. Squeeze the left clutch, press the
switch down (top bottom), then press the
start button (lower switch)
4. Starter will turns and making sound.
5. Look at the Black Rubber Fuel Hose that you
just disconnected. If you don't see fuel
coming out the ATG Petcock is defective.

If you are lucky, you can remove the ATG Petcock out of the gas tank. Be very careful when pulling out the ATG Petcock, because ther is an ATG Fuel Filter is attached to the ATG Petcock.
The filter maybe clogged and you can clean it.

Trial & Error
by: Loosegrit

Jim has a lot of good thoughts. You cannot work on starting without a good battery. If yours is not holding a charge well Walmart has a small battery for only $30 that fit a lot of scooters. Look in the auto section with the others batteries.

You say you got it started and now it won't start. What happened in between? I would change the spark plug, charge the battery and try again. Today's ethanol based gas can cause gunk in the carburetor but I would like to see a new spark plug in it as a base line. CDIs love to crack the insulators on a plug and a new one is always called for when you're not sure. Also, when you put in the new plug, spray some starter fluid in the engine, put in the plug and then try to start it. Sometimes it just needs a little shot to get going.

Still curious
by: Brian

I am not really sure what you are saying. I understand your point that you can't leave gas in the carb, but how would that explain it starting before and not now?

I'm not a mechanic.

You can not let gas sit in the carb. Modern gas leave a vanish film. If you feel you can take the carb apart and use spray carb cleaner. YouTube has videos to show you how.

Personally I just buy a new carb ( online about 45 to 60 dollars ) they are easy to change. For adjustments all you have is the air/gas mix screw use 1/4 turns until you find the right setting.

Its may be time to replace the battery.

Ether may start the scooter but won't solve the problem.

Good Luck and hope you get back to scootering soon.

Battery Tender Junior in package

A battery tender like the Battery Tender Jr. can make all the difference in whether your scooter will start right up each spring, after being stored for months.

Just about every scooter owner needs to have a battery tender, sometimes called a trickle charger. Unless you are lucky enough to live in a climate where you can ride all year long, chances are your scooter will be put on ice, figuratively-speaking, for at least a couple months every winter.

One of the key steps in winterizing a scooter is to protect your battery from draining during its "rest" period. This can – and will – happen if you leave your battery sitting untended in your cold scooter over the winter, even if it's in a garage or shed.

Read our review or go right to to buy this highly recommended Battery Tender Jr NOW...
