Whoever bought an automobile will know the word run-in or break-in. Let’s see what this term really intended for.
In simple terms that’s the period where you need to take utmost care of the Bike’s engine, and the dealer might give advice on not to rev hard, and stay with in specific rpm limit till you reach the manufacturer specified run in miles as per the manual.
Run in Period – What is it?
How long I need to wait?: Most manufactures mentioned 2000 or 1500 kilometers as the run in period, but if it comes to servicing they mention either days or kilometers whichever is earlier.
Do all the bikes engines break in exactly at the particular kilometers mentioned in the manual?: Do you think all GS150R/dazzler engine settles exactly at the time you cross 1500 kilometers on odometer, that can’t be true as it’s not a time bomb blast at exact kilometers. The kilometers mentioned in your bike manual is applicable under idle riding conditions, which means your bike engine and other core parts settling time depends on how you handle/maintain it and the environment it passes thru.
My friends FZ 16 breaks in at 1300 kilometers that doesn’t means yours also does it at the same kilometers it depends up on the above said criteria who knows it may take 3000 kilometers for your FZ. To say that in simple words run in period is the time where you are writing your bike’s fate for rest of its days.
Why Run in or Break in required?: It’s a new bike all internal core components such as cylinder, piston are brand new the bike may have run just 3-4 kilometers before it reaches you hence engine need to settle down making things inside it smoother.
They set everything and do all sort of QC checks then why do I need to run-in again? All moving parts of the engine are manufactured in such a way to fit precisely with one another while it was running, but in real time (practical term) this can be done after you run-in the bike for certain kilometers, during the run in period this moving parts rub against each other and get polished and they get synchronized perfectly to play the beautiful engine. During this period lubricant plays a vital role by setting the thin coat of lubrication on all engine parts.
So one should handle the bike in a soft way, if you rev it hard to reach the red line in the run in period it makes more metal to metal contact resulting more wear and tear thus it spoils the engine performance over quick period of time. So proper break in provides longer engine life.
Hey wait I read it some where on net on how to break in / run in can be done in overnight or within a day. Is that true? Yes, that is. But not for all. On those sites they advise to rev hard and harsh on all the gears so as the engine will break in with in hours.
That is applicable only for race bikes; a race bike can’t wait for 1500 kilometers to win a race because those bikes have to run faster but those super bikes engines have shorter life span and in the race biker’s world there is no word called mileage
How to do a Proper Break-In
The following are the key points to break in.
- Never stress the engine by any mean.
- Refer your bike manual and play with in the specific rpm limit
- Do not ride on constant speed for a long time (that doesn’t mean your bike should make vroom vroom vroom noise) Vary speed means instead of sticking to 45 kmph try to vary between 40 to 50 kmph.’
- If possible try to avoid steep / hilly terrains (our Indian roads are terrains in most places)
- Give regular breaks during long drives.
- Accelerate and de-accelerate in a slow and smooth way
- Try to avoid heavy pillion rider because that will stress the engine.
Do’s and Don’ts of Engine Oil
- During break in period engine oil changing duration is shorter, (in other word engine oil life is shorter so as to ensure engine life longer) so check the level, quality and quantity of engine oil regularly.
- Use only mineral or semi synthetic oil during the run in period, the reason being is the engine moving parts need to rub and get polished with each other, synthetic oil has high lubricating properties thus it will result in uneven polishing of engine parts.
- Careful in Engine oil changing intervals during run in period
- First oil change in 200 kilometers, Second oil change during first service or 750 to 850 kilometers which ever comes earlier. Third time oil change at 1500 kilometers.
- This frequent oil change will ensure most of the scrapped metal particles get removed along with the oil.
- Oil filter change will do well, but it’s not mandatory.
