Sometimes the engine manufacturer does not clean out the engine castings very well and some of the machining particles are left in, which add to the wear particles you find in the first 2 or 3 oil changes.
Thats why I always change the oil at 1/2 the mileage listed in the owners manual for the first 3 oil changes.

I wonder how many scooter owners have seen a scored piston? It only takes one small piece of metal to stuff up not only the bore but also the piston too.

Its too late after the event to say, "it will never happen to me."

On a Honda C50/70/90 my old manual said change the oil every 300 miles! I wonder what the chinese copies of these engines require?

The most common engine fault with C50s used to be people forgetting to change the oil and thrashing the little engine til it seized!

I read somewhere the Chinese copies of these engines require oil changes every day, or at least every 7.5284 miles.

JIALING!.....

Did you ever stick those magnets on your oil plug?

I have finally got a nice small magnet that's gunna do the job and will not interfere with anthing.
One you remove your sump plug, you will find that there is a spring that holds up the oil filter onto the internal crankcase.
At the bottom of the actual sump plug you will find a nice big hole that the spring sits in.
Wash the plug, spring and filter in a drop of petrol and allow to dry while the engine oil is draining.
After its drained put the small magnet into the base of the sump plug followed by the spring. You will find the magnet is drawn onto the spring and sticks to it. This is normal and it stops the magnet from moving about. The spring being a cage, traps the magnet so it cant wander or cause any damage to the internals of the engine.
Last place the filter on top of the spring and put the lot back and tighten it up, then fill engine with oil.
The next time you do an oil change you will find tiny particles of metal sticking to the magnet. These can be removed quite easily on the next oil change.
If you ever find large pieces of metal, then you have advanced warning something is amiss and you may need to strip your engine and find out where that metal is coming from.
It may never happen but that little magnet might just be a life saver or rather an engine saver in this case.
Either way for the pennies a magnet might cost its good insurance to know that you have added protection by way of that magnet.
Hope it helps Razz

at one time a flushing oil was used for an oil change, first the old oil was draind then flushing was poured in and the engine turned for a few strokes then drained, after that normal engine oil was poured in, as flushing oil is thinner it washes the parts of any thing that may have become cloged and the small metal parts easily washed out with it.

Shouldnt need to do this with modern oils. Just change your oil regularly and use a decent brand.

My dealer said never use flushing oil, just run some fresh oil through.

Use Amsoil Synthetic oil. It's the best oil for any engine, and probably too good for a Chinese scoot, but if you want engine longevity it can't be beat.
For you cheapscates, get used french fry oil from McD's or KFC.

I have a oil cooler on mine, I'm still trying to figure out a way to fit this magnet, I'm thinking of jb weilding an earth magnet to the outside of the plug, I'm sure the magnetisim of an earth magnet should be enough to draw some oil down.

also does any one recon it woul be hard to fit a remote oil filter between my hoses for the cooler???

"I have a oil cooler on mine"
your what?
"I'm still trying to figure out a way to fit this magnet"
you could always try what jialing has done, attach it to the inside of the sump plug.
"weilding an earth magnet to the outside of the plug"
suppose that's an idea.
"I'm sure the magnetisim of an earth magnet should be enough to draw some oil down."
gravity seems to do a good enough job for me?

"also does any one recon it woul be hard to fit a remote oil filter between my hoses for the cooler???"
can't see it being a problem

get some pics of your oil cooler up on site
