I am a first time Scooter Owner. I just noticed that my 150cc Lance Scooter has an oil leak. I have 2 questions on the issue. Where can you order Chinese parts? Without knowing where the leak is coming from, is a problem like this on a Chinese Scooter worth having a mechanic fix or will I be paying out of my to fix the issue and instead I should find a way to get it off my hands?

When mine started leaking and replacing the valve cover gasket didn't fix it I immediately started shopping for the next bike and eventually sold it. Oil leaking for no visible reason near my rear wheel is not allowed on my bikes...

Where does it look like it is leaking? Running from the top of the engine down, or lower, or leaking from a hose?

It is dripping off the engine, but I can't tell if that is where it's coming from or if it is dripping on the engine from a hose.

Clean the engine really well, making sure it is dry and clean all over. Then go for a good 10 minute ride with plenty of WOT. Come back and follow the drips up to the origin. Blowing a little baby power off your hand onto the engine can help locate the oil drip paths.

First thing to NOTICE is where are the drips. Left Side FRONT, Left side REAR, Left by the CVT COVER, Rights By the FAN etc..
It could be an easy fix so don't just give up. It could be from the VALVE COVER VENT HOSE(easy fix), It could be the Valve cover Gasket(easy fix), It could be from the TRANNY VENT HOSE(easy fix), It could be from the Tranny Drain Plug(easy fix), It could be from the CAM CHAIN TENSIONER(easy fix), It could be the CRANK OIL SEAL behind the VARIATOR(easy fix), If its the Crank Seal on the FAN side it is a little more work but still(easy fix) etc..
So don't let others scare you that you need a new motor or scoot.

Tracking down the leak is the hardest part. The Znen engines tend to leak along the left side of the cylinder where the timing chain lives. The mating surfaces are small on that side and don't seal well. Oil that escapes there gets blown all around by the fan air so it's hard to tell where the source is. They also tend to drip from the airbox where the little sponge is to absorb crankcase vapors. How you proceed depends on how bad the leak is and where you think it's coming from.
Chinese parts are quite plentiful nowadays. You just need to identify which make and model of scooter you have. GY6 engine and mechanical parts are very generic. Body parts are a little more tricky. The forum has many advertising sponsors that would be happy to work with you. (ScrappyDog is a good place to start) As well as the normal channels of Ebay and Amazon and a myriad of independent internet re-sellers.

The Znen engines on the Lance also seemed to have a tendency to get microfractures in the timing chain area on the side of the head. Take the cooling shrowd off the engine and connect a small air compressor set at no more than 5 psi to the valve cover vent and then spray a mixture of dish soap and water on the engine. Soap bubbles will accumulate where it leaks. I went through three heads on my Lance due to microfractures. |
