Lao Zheng then turned to the side and said to Chen Guo: "Little brother, these two are my friends, and they are also enthusiasts of internal combustion engines like me. I heard from me that you have two motorcycles here, so I came with me to have a long experience."

Lao Zheng’s two friends who were about the same age as him smiled and nodded to Chen Guo.

Chen Guo knew in his heart that these two should really be Lao Zheng’s friends, and he dared not say whether they were internal combustion engine enthusiasts, but ninety percent of them came to give Lao Zheng courage.

However, if you see through it and don’t say it out loud, Chen Guo pretended that he couldn’t understand it and greeted the two of them politely.

After a few simple greetings between the two sides, Lao Zheng asked Chen Guo impatiently: "My friend Chen, your two motorcycles..."

Before Lao Zheng finished speaking, Chen Guo smiled and nodded: "Everyone is in the yard, please come with me."

As soon as they entered the yard, Lao Zheng and his two friends were attracted by the two motorcycles, one red and one basket parked in the yard. The three of them didn't even bother to greet Chen Guo, and walked a few steps to the two motorcycles, looking at the two cars with their eyes lit up, but the next second, they looked at the water on the ground and then the water marks on the car, and the three of them were stunned for a moment.

"Little brother, you just use this car wash?"

Lao Zheng's face was not very good-looking, and it could be clearly seen that he was holding back his anger.

"What should I use to wash my car without water?" Chen Guo asked strangely: "I wash my car directly with clean water."

“…”

Lao Zheng was so excited that he couldn't speak.

The reactions of his two friends were not much better than those of Lao Zheng. It can be seen that they were trying their best to control their emotions. If they hadn't been forcing themselves to control their emotions, the three of them would have been cursing.

No matter how many Chen Guo came to the red Suzuki King GS125, please press the ignition button. The engine was easily knocked with the brisk sound of the starting motor.

Chen Guo took a step back and said with a smile: "Three, you guys, look at the car first."

As soon as the engine rang, Lao Zheng and the other two hurriedly threw Chen Guo's car with water aside, and immediately surrounded him and commented on this Suzuki King GS125...

"This car is the best!"

"This paint water is really good, it's hard to imagine how this car was preserved so well."

"It's not just paint water. When you listen to the sound of the engine, it is obvious that the internal parts of the engine are in very good condition. I bet that the overall condition of the engine is definitely not bad..."

…………

After more than ten minutes, Lao Zhengcai came to Chen Guo with a red face: "Little Friend Chen, can I try this car?"

Chen Guo frowned and said, "It's okay to try it, but Brother Zheng, should we do the work first?"

What's up?

Of course, it is the matter of installing a cruise control system on the gw250.

Looking at the Suzuki King GS125 in front of him, Lao Zheng was really envious and his hands were itchy: "Little brother, let's discuss it first..."

"Brother Zheng, I'm really sorry. It's not that I don't give you face, but that we have to do things first and then," Chen Guo's attitude was very firm: "If you help me do a cruise control well, I will sell you my motorcycle, otherwise our business will not be able to do it today... I said that I am not short of money."

Lao Zheng and his friends were speechless.

That's right. The reason why Chen Guo was willing to give this motorcycle to himself was because he could install a cruise control system on his motorcycle. If he couldn't do this, he would definitely not be willing to give this car to himself.

Since that's the case, Lao Zheng no longer hesitated and nodded, "Since you said that, let's do things first... Brother, can you find a place for us as a temporary studio?"

Chen Guo thought for a while and asked, "Can the living room be okay?"

"Okay," Lao Zheng responded, then turned to his two friends and said, "Old Wang, Lao Li, do a favor, remove the ecu and the throttle, and what we bring."

……………………

When Lao Zheng opened the black equipment box he brought, Chen Guo found that the two equipment boxes were filled with them. While picking things out, Lao Zheng introduced the uses of each equipment to Chen Geng: "This is a three-dimensional laser scanner, used to measure the three-dimensional dimensions of parts; this is a 3D printer, and some parts may be difficult to find, so we print them ourselves. Of course, it is limited to some things with low strength requirements; this is..."

This little thing is a 3D printer?

Chen Guo's heart moved and asked Lao Zheng inadvertently: "Brother Zheng, is your 3D printer expensive?"

Lao Zheng didn't care, and smiled and said, "This is an ordinary 3D printer. How expensive can it be? Well... it costs more than 1,000 yuan per unit."

What?

Chen Guo was shocked in an instant!

One thing is certain. Since Lao Zheng dares to use it to print parts on site, it means that the printing accuracy of this 3D printer will definitely not be bad. But a machine with such high accuracy only costs more than 1,000 yuan?

Chen Guo decided that when Lao Zheng and the others left, he must check the accuracy and price of this 3D printer immediately. Of course, the most important thing is the price of consumables.

In order to avoid revealing the stuff, Chen Guo did not ask much. However, Lao Zheng, after introducing his equipment to Chen Guo, said to Chen Guo: "Brother Chen, I have two ideas for this modification. The first idea is to convert the current pull-line throttle into an electronic throttle, and the electronic throttle is directly connected to the ecu, and then modify the throttle, and the throttle is directly controlled by the ecu; as for the second method, it is to retain the existing pull-line throttle, but this method is more troublesome and needs to be corrected..."

Is it easier to convert it to an electronic throttle?

Too!

With a 3D printer, isn’t it easier to modify the electronic throttle than keeping the pull-up throttle? Before Lao Zheng finished speaking, Chen Guo immediately said: “Just use the first method.”

"good."

Lao Wang and Lao Li were very fast. The three of them obviously had good mechanical attainments. They had taken down the gw250's ecu and throttle, and completed the measurement of the three-digit size and the 3D modeling work of the corresponding parts of the car body. Looking at Lao Wang and Lao Li who were discussing the modification plan of the throttle, Chen Guo was shocked: Is this three-dimensional laser scanner working efficiency so high?
