There are several types of cylinders of Tianhong 90 motorcycle

1. Normal. The original Tianhong 90 motorcycle is an 86-cylinder block, and the sound of Tianhong 90 motorcycle changing the middle cylinder is still the same, indicating that the replaced middle cylinder is also an 86-cylinder block, which perfectly matches the Tianhong 90 motorcycle. After replacing the middle cylinder, the sound and nature of the engine remain stable and there is no abnormality. Therefore, the sound of changing the middle cylinder of Tianhong 90 motorcycle is still normal.

2. The upper left corner of the Japanese cylinder is marked with 85cm, and the upper right corner is HM-C1 or HM-C2 or HM-C3 or HM-B1 or HM-B2 or HM-B3.Domestic products are rarely marked with 85 and most of them are 86, but there are also some marked with 85. The process traces at the left guide wheel hole are also different.

3. The motorcycle cylinders of Tianhong 90 are the same as 85 and 86. Motorcycles, two-wheeled or three-wheeled vehicles driven by gasoline engines and controlled by hand-controlled front wheels, are light, flexible and fast. They are widely used in patrols, passenger and cargo transportation, etc., and are also used as sports equipment.

4. Tianhong 90 was produced by the former Tianjin Honda. It adopts an imported Honda engine with a non-electric start 90CC and a 12V circuit. It is a well-known model in the 1990s. Changing the middle cylinder of Tianhong 90 to 86 will increase fuel consumption, increase the crankshaft and valve load, and reduce the cylinder compression ratio, which has a great impact on power.

5. Tianhong 90 motorcycle cylinders, 85 and 86 are the same.It's just that because the cylinder volume is rounded up after the decimal point and the tail number, if there is no rounding, it is written as 85, and if there is no rounding, it is written as 86. In fact, it is the same. Most manufacturers are marked 85, and there are fewer marked with 86.

6. Tianhong 9o motorcycle cylinder can be replaced with 86. 90 and 86 are the same. It's just that because the number of the decimal point of the cylinder volume is rounded up, the one without rounding is written as 86, and the rounded one is written as 90. In fact, it is the same. Most manufacturers mark 90, and fewer are marked with 86.

Can the Jialing high-pressure package igniter of Tianhong 90 engine be used?

1. Jialing 70 imported high-pressure package igniter and Tianhong 90 are not universal. Jialing 70 imported high-voltage package igniter and Tianhong 90 external meridian are the same, but the voltage stroke of Jialing 70 is shorter than that of Tianhong 90, and the two cannot be used interchangeable.

2. The high-voltage package and igniter of K90 are integrated and cannot be interchanged with TH90. The igniter and high-voltage package must be purchased (Jialing 70 is fine).

3. No. The magnetic motor of Jialing 70 and Tianhong 90 are the same, but the voltage stroke of Jialing 70 is shorter than that of Tianhong 90, so the two cannot be used in common. Motor refers to an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction.

4. Can't be used. Although Jialing 70 and Jialing 90 are both produced by Jialing Group, the difference between them is still very big. 90 The mouth of the 2 pins above: the left is turned off, and the upper row of the mouth of the 4 pins under the ignition power input on the right: the left output to the high-voltage package, and the lower row of the mouth of the 4 needles on the ground on the right: trigger on the left.

5. It depends on whether the original machine has not been opened! Have you changed the middle cylinder? The original cylinder is 85. It doesn't make much sense if it has been replaced! If you haven't changed it, I suggest you that you need Tianhong 90. Come back with a very durable horizontal cylinder engine. Theoretically, it is fine.Generally, it is an engine equipped with Tianhong 90.

Where is the original Tianhong 90 engine five-star

1. The oil filter of the motorcycle is often placed under the cylinder block, and then there are three bolts. In a tightened filter cover, 80% of the motorcycles are in, the engine On the right side, then remove the three bolts, open the cover and take it out. The oil filter is generally used for motorcycle filters, and the replacement cycle is 2000 to 3000.

2. Near the left spark plug. The engine number is uniformly engraved near the left spark plug at the factory, so the Tianhong 90 engine number is near the left spark plug, and the engine number can also be found on the vehicle driving license, which is compiled to prevent engine modification.

3. It is an imported machine. If the five letters "HONDA" on the engine are white and engraved on the engine, it is imported if you don't feel it. On the contrary, if the font is black and deeply engraved, it must be domestic.
