Running-in

Do you know if there is a baffle inside the exhaust and later how can I remove it?

If you allow me, I would remind you that CG clone, same one like on Foisix's bike, does not have real, removable, filter element, but oil spinner, aka. centrifugal oil filter. In order to reach this filter and open it (by unscrewing 3 bolts) and wipe all the sh&#, you must remove right side crankcase cover. In front of the oil pump, probably there is some sort of the net, so if you remove crankcase cover, you should see if there is something on it.

Foisix, do not look for Hi-Tec oil - this engine was developed at a time when there was nothing else, but a dino oils. Today, any decent semi-synthetic oil without anti friction aditives will do the job.

And, if you can, find magnetic drain plug.

So I don't have to change any filter?

**humanbeing** · 04-11-2015, 06:40 AM

It's based from CG125 ie. designed for developing country that needs cleaning ONLY

Ok I'll try, no pb for the moment the bike runs well , no vibration , good sound. 80 more km and I'll change oil.

Yes - no filters to change.

In order not to torture you my with my awful English, here's video guide to you to do the entire procedure:

BTW, there are "bolt/on" oil cooler kits for CG clones. Good thing, if you use bike in a hot climate.

By the sound of things and by watching the video you just have a very small finger type filter !! That you need to wash , never a good design engine are not incoperated with a better design filter TIC

Maybe it could be a good idea if when you change the oil you then flush the engine with a flushing agent before you fill up the engine with new oil , this way you can make sure all the fine metal deposit are total removed from your engine .

This "thimble" is a mere protection for oil pump, in order to prevent that some larger particles can not be sucked in. Main job is on centrifugal filter, although, today's oils have additives which dissolve preety good carbon deposits and resins that can occur over time inside the crankcase.

Also, it is possible to fit some oil filter, using engine head cover with oil inlet/outlet, the same which has been used to fit oil cooler.

And Foisix, it can be useful for engine hygiene to bring end of the engine breather hose somewhere under the seat (no dust there). I used a filter from my bike's SAI system, and put it on the end of that hose.

Ok , thanks a lot for all your advices , I'll send you pictures when I get to change oil... Another question, the gear box is a bit rough is it normal, because it's brand new?

**Zorge** · 04-13-2015, 06:33 AM

Rough in sense not smoooth shifting with a loud "clank" sound or it is noisy in any gear?

Yes, after some time, gearbox will become smoother, but picking adequate oil is also important. But I do not want to confuse you even more - you'll figure it out by yourself.

Also, you should check clutch cable - sometimes they are too loose and this clutch lever on the crankcase cover can not be pulled enough, so friction discs and plates are not disconnected completely, and as a results you'll hear that rough sound while shifting gears.

As regards this humming sound from the gearbox, there is no help. All gears are straight cut, so noise is their side-effect.

Oh my, this English drained me...
