Hi,
I read some advise on engine break-in, but it seems quite complicated!
Would I notice it if my engine had a good break-in period, or if I start cruising right after I mount it?
I don't think I have the proper know-how, or knowledge to break in an engine. And the scooter store around the corner does not want to do the maintenance on my BMS 260cc scooter, because it's a Chinese one.
That means I also need to figure out where to drop the dirty oil!
In other words, would it differ that much, if I just don't do a proper breakin?

There is nothing too complicated about the break in period of your scooter. For the first few hundred miles you don't want to do any fast hard acceleration, no wide open throttle driving. You also don't want to drone on and on at the same speed forever either. Vary your throttle settings from time to time. This gives the engine parts a chance to gradually wear into each other and allows the piston rings a good chance to wear in and seat properly. If an engine is not broken in properly it will never develop it's full potential regarding power and fuel economy. It will also end up using more oil than it should. If you just got the scooter, change the engine oil and the transmission gear oil now. Change the engine oil at 300 and 600 miles. At 1000 miles change the engine and transmission oils to full synthetics and your break in is done. Some people say less miles and some say more for the break in but this is about average. The further you get into the break in period you can start increasing your speed some, just not right off the bat. Working on these things is pretty easy, even for beginners. There are the forums to help you along as you need it and here is a pretty good reference lilnk that answers a lot of questions. www.chinesescooterreference.com/scooter_intro.htm |

The problem is the conflicting opinions on break in online.
I've grown to understand break in period like you describe, but there are others who swear by fast acceleration, low rpm's in the beginning, and regularly rev the engine in high rpm's without load...
then there are those that swear by low acceleration in the beginning and gradually working your way up
If both conflicting opinions could work, wouldn't it make sense that perhaps not caring about break in at all, and just drive the bike around like you would normally is just as good?
(Basically acting like there's no such thing as a break in period).

There is much controversy about break in methods. I subscribe to the Motoman method. Run it hard from the get-go but don't flog it. www.mototuneusa.com/break_in_secrets.htmMy longest lived best running bikes and scooters were broken in with this method. |

I broke in my 150cc as I described above. By the end of the break in period I noticed an increase in top speed and acceleration. All I know is it worked for me. I haven't tried the "hard" break in method, and unless by some miracle I suddenly have a bunch of extra money laying around, I won't.
Whichever method you use, keep changing the oil regularly for the first 1000 miles.

Aluminum engines do better with a fast and hard brake in. You really don't need to slowly brake it in anymore.

I have a 150 gy6 and as soon as I got it out of the shipping crate put it together, looked it over, put gas in it and rode it hard changed the oil at 10 miles 50,100,300,500,1000. I take off hard and hold it wide open for long periods. I have not had any problems with the engine or trans so far. But I am hard on every thing so just ride it like you plan on riding it most important is change the oil I had lots of metal shaving in my oil at first and these engines don't really have a filter.

The problem with a CVT is that when opening the throttle, the RPM's can rev up too high!
The user manual clearly states not to rev up the engine too high in the break-in period.
With a manual transmission one can shift the gears and keep RPM's low while keeping a high torque on the engine.
