You should also check for a spark when turned out. Resistance is measured between ground and a black wire with a red stripe.
To do this, you need to disengage the clutch, simultaneously reduce the engine speed and engage second gear. For example, the Kovrov Motor Plant abandoned its own production of power units and installed the Lifan engine on its models. The operation of the motor is blocked by interrupting the spark supply from the coil. Electrics on an Alpha moped
Electrical equipment Adjust the sound signal by rotating the screw on the front cover of the signal.
For products with an instrument panel containing a tachometer, we publish part of the diagram, which also has differences in the controls. Place the gear shift control knob or lever in neutral.
Generators can also be different: 2-coil tachometer with two wires, 6-coil tachometer with three wires. As a result, the relay regulators will differ.
Spark plug Its function is simple - to create a spark and ignite the mixture inside the cylinder. Until the battery is discharged, the scooter will work, and then the engine can only be started by charging the battery or replacing it with a new one.
With the gearshift mechanism properly adjusted and in neutral, there should be no sound of the clutch rubbing against the gears while the engine is running. Clean the brake pads.
ALFA 110: Problem with starter and light
Let's start repairing the Chinese miracle of technology
The Alpha 72cc moped is one of the most famous representatives among Chinese motorcycles.
This moped is perfect for use both in rural areas and on city roads. A durable iron frame, complete absence of plastic parts, large diameter wheels - simply created for domestic roads, the quality of which is far from European level. If you ride often, the rather high seating position of the ALPHA moped makes it possible to overcome low obstacles. A big advantage when choosing a moped is its low price, which makes the purchase quite affordable. This would be a good choice for a beginner.
There are models with a side trailer. Practical to use in rural areas. A reliable assistant in the household.
Economical, with an engine capacity of 72 cubic meters and air cooling, the Alpha moped is unpretentious. This is an extremely simple transport and servicing it couldn’t be easier! You simply cannot find a simpler engine, and spare parts cheaper than Alfa’s can only be found in a dream.
Anyone can carry out tuning or repairs on an Alpha moped with their own hands.
Before you start disassembling the motor, you should fix it on the center stand and completely remove all the plastic. All power systems should be turned off - tank, carburetor and fuel filter; The oil should also be drained.
The engine should be removed along with the transmission, and the Alpha moped should be repaired on a flat surface.
You can remove the alpha engine according to the following diagram:
- remove the muffler and exhaust pipe;
- remove the camshaft gear cover;
- unscrew all 4 bolts from the cylinder cover;
- remove the top cover and cylinder head;
- We study the degree of wear of the valves, check how dirty the insides of the system parts are.
Is this your first time repairing an Alpha moped yourself? No problem! A moped is not a hadron collider; nothing has changed in 50 years of moped construction. For convenience, draw a diagram of the location of the parts so that later you can complete the assembly without any problems.
A smartphone can help, take photos of each step so that later you can reassemble in the reverse order without confusion.
If it is necessary to replace the valves, or if there are gaps in the fit, then they need to be removed:
- Place the head on a level place. To prevent the valve from being damaged during dismantling, it is better to place a layer of thick rubber or a rag under it;
- we select the socket head, place it on the valve plate and hit it hard with a hammer;
- release the crackers, remove the top plate and valve washer;
- remove the valve and guide bushing. To complete the repair of the Alfa moped engine, after replacing the parts, we begin assembling the engine in the reverse order, putting everything in its place, observing the marks. Don't forget to add fresh oil.
The gearbox of an Alpha moped often fails and requires constant attention. The author of this article got the sprockets stuck in the box while driving in 4th gear 10 years ago. When trying to force a gear change, for some reason the gearbox automatically selected first gear and the moped was driven at a speed of under 100 km/h. just braked without throwing the author of this article over the steering wheel
