Wet plate clutch?

[Huggyd]

I picked up a chinese 125cc atv used. Was going to do an oil chance before the little guy starts riding it. From my understanding these have a wet plate clutch in them. When looking up the type of oil to use I see 15W/40-SE, 4 stroke Oil was recommended. I was wondering when I head to the store does the SE signify its ok to use with a wet plate clutch? does it say something on the bottle that it can be used for a Wet clutch??
Also from what I read there are no oil filters to change on these, does that sound right?

An insight is helpful.

It could have a centripetal filter or not even that. If you only see one drain bolt it's a shared sump and likely so as split sumps are more expensive. Just about any 4t 10w-40 will be fine. I'd buy the cheap stuff like moto master or castrol go and change it every 50 hours. If there's no filter I don't see much reason to use better oil in it.

If it has a wet clutch I would go with a JASO MA2 rated oil.

You can pickup a quart for about $9

EDIT: Javier is correct any oil that says 4t should be fine

ok thank you, so 4t is what I am looking for. I wouldn't expect it to say 'Wet clutch' anywhere on the face of the quart ??

does any of these signify wet clutch: API SL, JASO MA-2, ISO-L-EMA2

Any common diesel 15w-40 oil will be fine. No need to spend double on MA/MA2 oil.

Anything that says jaso ma should be fine. In reality any motor oil without friction modifiers should be good like rotella T oils as they do say jaso ma though they don't seem to hold up to foaming well but I haven't heard of issues either. Most say 4t, motorcycle, powersport, atv or utv or both. Many use oils with friction modifiers and don't have issues but most have healthy clutches and they also don't lug the engine like putting it in highest gear and flooring it as that may make the clutch slip or at least slip a lot more with an inappropriate oil containing FM as opposed to not so those that are easy on their bikes and immediately change the clutch once it feels worn don't seem to have issue using regular car oil.

You'll be fine with any readily available 10w30, 15w40, even 20w50 if used in hot temps.

I mail ordered a 110cc 4-wheeler for my kids about 15+yrs ago. Very basic single speed gas and go. I believe these use a centrifugal clutch that shares the crankcase oil. That little ATV was a blast.
