The recommended break-in time is typically 1,000 miles (1,600 kilometers), within which there is another critical time point: 500 miles (800 kilometers). Be careful with your engine during this time.
First, depending on the manufacturer, there will be a requirement for the maximum speed the engine can operate at. Kawasaki requires a maximum speed of no more than 4,000 RPM within 800 km. Yamaha's requirements are relatively relaxed, with a maximum speed of no more than 8,000 RPM within 800 km. Between 800km and 1600km, kawasaki's requirement is no more than 10000rpm and yamaha's is no more than 11000 RPM.
Although the Japanese manufacturers have such requirements, but there is no rigid limit on the maximum speed. If you want to drive the car to the red zone at 0 km, you can still do it. BMW has more stringent requirements in this regard. For example, a new BMW S1000RR needs to unlock the RPM twice in its life to use the full RPM (red zone RPM).
Over 800 km, solve the 6000 RPM limit; over 1600 km, solve the 9000 RPM limit. The restriction is mandatory and must be lifted at a designated BMW dealership. If the speed limit is not lifted, the car will automatically run out of fuel when it reaches the speed limit and will not be able to perform at its best. (it can be seen that modern motorcycles need to be run in.)
Secondly, I believe that many people can insist (or endure) not to exceed the speed limit, but this is not the main requirements of run-in. During the run-in, one of the most misunderstood problems is that you need to use your engine gently and keep the speed as steady as possible. It is also wrong to keep the speed stable all the time, which is not good for the running in between the piston ring and cylinder wall.
The correct run-in method is: try to use the available speed. If the RPM limit is 6000 RPM, try using a range of 3000 RPM to 6000 RPM, shift gears frequently, and drive at an unsteady speed. Ride on a hilly road or a national highway where traffic is easier but you need to speed up or slow down.
1. Preheat the car (the engine reaches the specified working temperature) before riding.
2. Avoid sharp acceleration and braking except in emergencies.
3. Don't pull the gear, slow down the gear in advance, keep the engine in a comfortable running state.
This faction insists on relatively violent methods, such as horse power and track running. (note that violent run-in is not the same as unbrainy run-in)
With this method, if you can find a professional horsepower engineer or a race track to use, the running time will be greatly reduced. The new engine can be completely polished in 20 minutes on a horsepower engine in one race day.
In view of the domestic horsepower machine few and few, the track is not the ordinary car friends can easily access, here to introduce a relatively simple violent run-in method.
1. Check the vehicle to make sure the oil is in good condition. Start the car and wait for the engine to reach its normal operating temperature.
2. Look for a highway that has good traffic and allows you to drive gas faster (at least at a low speed). Then start from low RPM (the first third of the vehicle RPM, if your engine red zone is 15000 RPM, low RPM
It's 5000 RPM, or a little bit lower) pull it down to the medium RPM (15,000 RPM in the red zone of the engine, 7,500 RPM in the medium RPM), then slow it down, or shift it up to bring it down, and repeat.
After 20 kilometers of driving like this, pull over, turn off the engine and give the car a rest for 20 minutes.
4. After the break, repeat step 2. This time the maximum operating speed will be up by 1000 RPM. (if the previous maximum was 7500, this time it will be 8500). Also, after a 20km ride, stop, turn off the engine and rest for 20 minutes.
5. Repeat repeatedly. After each rest, the maximum speed can be added up to 1000 RPM until the speed reaches the red zone.
Both methods have plenty of success, and you should be able to grind a new engine with either method, as long as it's not brainless roughing. Which way to choose depends on personal preference.
Talk about oil change (oil filter), generally speaking, after the first 800 km, should be immediately changed oil. This time you can use the standard mineral oil. Mineral oils are not only cheaper, they also help the engine blend in better at this stage. (full synthetic oil is too thin to effectively help the engine blend in at this stage)
After 1, 600 kilometers, you can start using a fully synthetic oil. Some people like to blow synthetic oil into the air, thinking that it will increase power, protect the engine, and make the engine work more smoothly. Most of the benefits are psychological.
(1) help the engine better cope with different weather conditions and temperature changes;
(2) the service life of fully synthetic oils is longer than that of ordinary mineral oils. You can continue to use the manufacturer's common mineral oil, remember to change it often.
Another myth about oil is that you should change the oil after the first 50 kilometers and then change it again after 300 kilometers. This is good and harmless, and the oil must be fresh and good. But no one knows for sure how much of a benefit it would bring, or whether it would be worth the time and money spent.
My personal opinion is that 800km and 1600km oil replacement is enough. (of course, if you're riding in a crashy way, it's ok to change the oil a little earlier, 500km or 1200km.)
Matters needing attention for motorcycle running
1. After getting the new car, first check whether the key parts are loose. Then add gasoline and oil, gasoline label should be high and low. Oil is the best place to buy a car to choose the car special oil, and had better always use the same brand of oil, because different oil mix easy to produce precipitation, oil should be added enough, can not add more can not add less.
2.We can start the car on the road after all the preparations have been done. Try to change gears as much as possible during the ride. The goal is to get the gears in each gear to fit. Do not exceed the speed of each gear, and do not have too much weight, try to drive on a relatively smooth road.
3. The run-in mileage of the motorcycle is about 1500 kilometers. The time for oil change is usually 300 kilometers, 500 kilometers and 1,000 kilometers.
4, the bike to 500 or 600 kilometers can start to climb some steep slope or load some heavy weight, this gradually stimulate the potential of starting motivation, occasionally appropriate with 5 speed run.
5. At the 1500km, you can go to the after-sales service to replace the air filter and oil filter. At this time, it is better to clean the debris inside the engine.
6. After 1500 kilometers, the car has basically finished running in, and we can start to ride normally. At this time is generally 3000 km oil replacement, 1500 km or 2000 km replacement of an air filter or oil filter.
