SOURCE: 2 stroke engine smokes. how do you adjust the fuel/oil mixture?

The thing with two strokes is that they smoke a bit under normal operation, and they smoke like mad if they haven't really been run for a period of time, I would advise you to run it for a while and see if that helps.

You should not need to adjust the mixture settings at all.


Hope this helps

SOURCE: what oil should i have in yz 125 2 stroke

The clutch and gearbox share the same oil. The oil for the motor is 10w40. Stick with the major brands; Pennzoil, Quaker State, Mobil, Yamalube or Shell.

SOURCE: I have a 150cc jonway scooter. When I open it up

I found that if I run 87 octane gasoline the engine accelerates up to full speed without the skipping and bogging down at any point it is running. It is worth trying. also try putting some "Sta-bil" fuel stabilizer in the gasoline - it has the ability to keep the carbureator cleaner. Not just during the time you are storing it, but rather all the time.

SOURCE: how do i derestrict my lifan s-ray 50cc 4-stroke

Unless you find a small "restricting washer" between the head and the exhaust pipe...Then usually there is no easy means. In the past these "washers" were put in place to reduce performance, the idea was as the riders skills improve the washer can be removed. It also was a way for parents to keep their children from zooming flat out everywhere.

Jonway 125 will not start


Hi, Koos and the usual suspects are:
1. Fuel tank empty.
2. The fuel tank has old dead gas.
3. Fuel tank bottom contaminated with ethanol sludge, dirt, water, rust, etc.
4. Fuel supply valve/petcock turned off.
5. Fouled spark plugs.
6. Engine flooded as a result of overuse of the enrichner.
7. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
8. Fuel valve/petcock or filter clogged.
9. Fuel line to carburetor or throttle body pinched, kinked or blocked.
10. Carburetor float stuck.
11. Fuel injectors clogged.
12. Fuel injectors stuck open.
13. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a cursory reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead acid batteries.
14. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
15. Loose or corroded wire connection at the coil or plug between ignition sensor and ECM module.
16. Spark plug cables in bad condition and shorting check for spark leakage in the dark, cable connections loose, or connected to the wrong cylinders.
17. Ignition timing incorrect due to a faulty ignition coil, ignition module or MAP, CMP, CKP, O2, TPS, ETP, IAC sensors.
18. Faulty neutral, clutch lever, or kickstand safety switch.
19. Faulty fuel pump or fuse or relay.
20. A stuck bent or burnt valve.
21. Tilt sensor needs a reset.
22. Security system not disarming alarm needs a reset.
23. Check for engine trouble codes.

Is my 2005 qiangiang gmi 108 a 2 stroke or a 4 stroke


Hi, David engine design is very easy to identify:
TWO STROKE
1. Two strokes red line around 12,000-16,000 RPM.
2. A reed valve is in between the carburetor and cylinder head.
3. The exhaust has an expansion chamber.
4. The muffler has a small diameter tail pipe.
5. The exhaust has a high pitched Bap Bap sound.
6. Small scooters and small dirt bikes are generally 2 Stroke.
7. Older models had adjustable throttle actuated oil injection.
8. Older models had a premix ratio of 2 stroke oil and gas.
FOUR STROKE
1. Four strokes red line around 6,000-8,000 RPM.
2. Four strokes have camshafts and valves.
3. Mufflers have large diameter outlets.
4. The exhaust has low pitch deep rumble sound.
5. 350cc and larger engines are usually 4 strokes.
6. Four strokes have separate oil tanks that feed an oil pump.

My scooter wont start can u help


It is definitely frustrating when you can't get your scooter or moped started. The first thing you'll need to do is to narrow down the problem. In order for your gas scooter to start, it really only needs 3 things:

1.
Your scooter needs to spark at the correct time.
2.
Your engine needs the proper fuel/air mixture and exhaust flow.
3.
You need sufficient engine compression.

Top 9 Reasons Why Your Scooter Won't Start:

1.
Try depressing the brake handle when starting.
2. The battery has not been charged.
3. The battery is hooked up wrong. This is often the reason for blown fuses.
4. There isn't enough gas or two-stroke oil in the scooter.
5. There is a gas flow problem, especially on the Euro Scooter or Yamaha models.
6. The spark plug wire is not connected.
7. A low battery or bad relay can cause the scooter to only start by using the kick starter.
8. There is no spark to the spark plug. The coil is bad and needs to be replaced.
9. Turn the key to the "on" position.
