इंजन का काम कराने के बाद क्या सावधानी बरतनी चाहिए? | HOW TO BREAK IN YOUR REBUILT MOTORCYCLE ENGINE

Описание: If you spent lots of money and hours of hard work rebuilding the engine in your motorcycle, scooty or scooter the last thing you want to do is ruin all that hard work by failing to properly break in the motor. The steps to follow for breaking in a rebuilt engine once it's running again will vary slightly depending on the type of engine. For example, the steps for a high-performance street bike requiring high RPM for peak performance differ from a more sedate side-by-side that relies on lower RPM torque to get the job done.

Adding Conventional Motor Oil
Fill the motor with a conventional engine oil, not a synthetic. Synthetic and semi-synthetic oils are too slippery and slick, which prevents the new piston rings and cylinder bores from seating properly. During the first few minutes of running, the piston rings and the walls of the cylinders need a small amount of friction so they can wear fractionally, and so their surfaces can conform to one another to form an effective seal. It's this seal that gives an engine good compression, and it's that compression that really adds to the performance of your rebuilt engine.

Static Engine Run to Operating Temperature
The first time you restart the motor after a rebuild should be a static run. Wheel the machine outside or make sure you're in a well-ventilated space. Then, start the engine and bring it up to operating temperature while gently varying the throttle between idle and 50% open. Don't go over 50% throttle at this point. Once the engine has warmed up, give it a thorough inspection for any leaks; listen for any odd noises; and look for any other mechanical issues such as excessive vibrations. Shut off the engine and let it fully cool down.

20-Minute Active Engine Run
An engine break-in happens mostly during the first 20 minutes of running after the rebuild. If you have access to a dyno, strap the vehicle down and vary the load on the engine between idle and 70% throttle. Otherwise, take the vehicle for a short ride to put a load on the engine. Vary the throttle between idle and 70% to push it a little harder than you did in the static test. Find somewhere without any traffic where you can safely run the vehicle while varying your speed to break in the engine.
Assuming everything goes well and there are no mechanical issues, start varying the throttle between 50% to 80% to further increase the load on the engine. Next, run the vehicle as you would in normal operating conditions.
