Lexmoto Hunter 50cc

[Joe_Cawthorne]

I own a lexmoto hunter 50cc motorbike. I recently did an oil change on it and want to change the oil filter too. Looking on the manufacturer website, I can only find an oil strainer. Assuming that this does the same thing, where is it located on the bike?

It may be on the left quite low down on the engine or under the fan cover. It looks like a bolt with a big washer behind the head.

If this bike has a copy of the famous HONDA engine then there is no classic oil filter,

but a centrifugal one located under the clutch cover, either a round case on the right end of the crankshaft,

or under the clutch actuator bearing support plate, secured to the clutch basket with crosshead screws.

Worth finding and cleaning that, all oil passes through the centrifuge and crud accumulates on the outer edges.

Top row, first pic = clutch basket centrifuge (watch out not to damage gasket while removing cover)

second pic = centrifuge on crankshaft (screwdriver pointing at crud)

If you have the "clutch basket" version, the countersunk crosshead screws will be a PITA to crack open

as they have JIS heads, a philips screwdriver will not engage properly until you grind some mm off the tip.

(See allen countersunk screws in 1st pic as replacement)

Also, put one or two pieces of wood under the clutch basket as it moves inward a bit if pressure is applied.

AND if you take the outer clutch cover off take care of the gasket, and look closely at small parts

of the clutch release mechanism, be sure to put them in the same way they came out.

Thanks for all of the useful info. the item that i am looking for is called and oil strainer. it is listed on the manufacturers website for the bike in question. i have included an image of the part. i cannot find it anywhere on the bike.

If you have removed the clutch cover, but the big gasket is still stuck to the cankcase,

the oil screen it is hidden behind the gasket, it is located on the bottom of the crankcase

because it is positioned before the oil pump intake.

Apologies Joe, I wrongly assumed a Lexmoto Hunter was a 50cc scooter.

I have just had a look at that image and have taken my bike apart but there is still no sign of an oil filter/strainer.

Following on from Benni's post are you sure its not tucked away in a slot at the bottom of the sump? This vid might help https://www.youtube.com/watch?v=BLuTESXVXWE I appreciate this is for a different make and model, but a lot of these bikes have engines that are clones/evolution of the old Honda Cub as already said.

Thanks to everybody for the suggestions, I eventually found the part I was looking for. It was hidden behind a gasket.

[Joe_Cawthorne]

The part itself is way smaller that I had originally expected.

Result !

Don´t put everything back together until you have removed the 4 crosshead screws on the clutch basket,

the filtering is happening right behind that part and most of the dirt in the oil is collected there.

The strainer is only for the biggest "foreign objects" and picking up chinese workplace leftovers....8-)

My bike is playing up. No surprise for such a cheap pile of Chinese sh¡te. I was riding along the other day and it suddenly started to loose power. And eventually cut out. I have checked my spark, very clear spark. I have cleaned my carb out, no different. There is definitely fuel going into my carb but there is nothin going into the cylinder. I tried squirting fuel directly into the spark plug hole but even then it won’t start. Please help!!
