Why does my scooter not start at 100 psi?
If it’s 100 psi or less there’s likely and engine problem (bad valve, bad piston, failed piston rings) which will need the engine taken apart to find. Probably the most common problems are a dead battery or carburetor problems due to bad adjustment or build up of gummy deposits.
What to do if your scooter engine does not start?
If this does not work, check the fuel line for kinks. If there is spark and the fuel is flowing into the filter, pull fuel line off of carburetor and make sure that fuel is getting through the filter and into the carburetor. If it is and the engine will not start, the automatic choke could be inoperative.
Why does my Powersports scooter keep bogging down?
Usually bogged down is caused too much gas going through the carburetor. Give time for it to warm up. If that does not solve the problem, you need a new carburetor. Check the gasket between the carburetor and intake manifold. It might be bad or maybe the carburetor came loose due to engine vibration. My scooter is not holding its charge.

This is a key test to run before you go through the trouble of disassembling your carburetor. To set up this test start up your scooter and ensure the choke is off if your scooter has a manual choke. Most modern scooters have an automatic choke so don’t worry.
What should the voltage be on my scooter?
It should be somewhere in the region of around 10 or 20 ohms. If it’s an open circuit, it’s burned out and will need to be replaced. If it seems to be OK it may be stuck, or the wiring to it may have a problem. Check to see that it’s getting voltage.
What to do if choke on scooter wont start?
If the automatic choke is OK, the starter cranks the engine, there’s gas and there’s a spark then there may be an engine problem. You need to check the cylinder compression. You need a compression tester to do this. It screws in instead of the spark plug and measures cylinder pressure.
What do you need to start a electric scooter?
To start a scooter needs three things: If your scooter won’t start it due to one of the above not being present. Before you start troubleshooting, make sure there is gas in the tank by actually looking into it. Don’t just trust the gas gauge!

Is there enough power in a 50cc Scooter?
On a standard 50cc scooter, there isn’t normally enough power to warrant sacrificing some for higher top speed. However, on a scooter which has already been tuned up to stage 2 you have some power to play with.
What happens when you make twice the power on a scooter?
It is important to note that with your scooter at this stage making approximately twice the power it has been factory designed to produce, moving parts will tend to wear faster and have a higher tendency to break if not maintained correctly.

What to do if your scooter won’t start?
Collin shows us how to manually choke your scooter at the air filter to help get it started. These 4-stroke carbureted scooters can be challenging to start if you have left them sitting without use for a period of time because the carburetor can get a little gunked up with stale fuel.
How can I check if my scooter has a spark?
To check for a spark, remove the spark plug from the cylinder, hold the tip of the plug against the cylinder head and crank the engine. You should see a spark across the gap.

Why does my spark plug not start my scooter?
If your attempt at starting your scooter is met with only a small amount of sputtering, your spark plug may be the culprit—or your battery. If your spark plug isn’t sparking because it has broken, your engine can’t explode the compressed fuel. Spark plugs are relatively cheap to replace, luckily. Often there is an even simpler issue, however.
What should the resistance be on a scooter?
If you have a voltmeter you can measure the resistance across the leads of the choke. It should be somewhere in the region of around 10 or 20 ohms. If it’s an open circuit, it’s burned out and will need to be replaced. If it seems to be OK it may be stuck, or the wiring to it may have a problem.
What should the PSI reading be on a scooter?
When you crank the engine you should see a reading of around 150 psi or more. If it’s 100 psi or less there’s likely and engine problem (bad valve, bad piston, failed piston rings) which will need the engine taken apart to find.

If the speed controller has no burned or melted wires and it does not smell burnt then it still could be defective. Test all of the other components of the electrical system around the speed controller and use the process of elimination to detect if the speed controller is working or not. Speed controllers are too complex to easily test.
What’s the maximum power of a 150cc scooter?
If the scooter has a tachometer (rev counter), it makes life easier because you can see what’s going on. A typical 150cc scooter engine makes maximum power at around 7500rpm. If you accelerate at full throttle and the revs rise to about 4500rpm and pretty much stay there, then the rollers are too heavy.
What’s the maximum speed of a 50cc variator?
Typicaly a 50cc scooter might be restricted to 7000rpm. The Variator has an oversized boss to limit maximum speed by not allowing the full range of gear ratios. All these together limit the scooter to a maximum speed of under 30mph (as required by regulations for non licensed riders).
How do you remove a restriction on a 50cc Scooter?
Simply grind off the small welding spot that hold the restriction in place and it can be easily removed. To avoid that the restriction piece falls into the manifold when grinding you should build a hook out of some wire and secure its position. There are some other exhaust restrictions.
Can you increase the capacity of a 50cc Scooter?
You can increase this with a Big Bore Cylinder kit. This can increase the capacity of a 50cc scooter to 70cc or 80cc. You don’t see many big bore kits for larger scooters because their owners are not trying to make their scooters look like a 50cc scooter for licensing reasons. Note that all these parts have to work together.
How big of a carburator do I need for a 50cc Scooter?
This means that the manifold at its smallest point needs to have a diameter of at least 12mm as well. Otherwise the carburator can not work at its maximum performance. Cheap replacement manifolds can be found on eBay for around 15€. They are a good investment and can be used for carburators up to 21mm diameter in size.
