whirring noise zongshen 250
 

Hello people, I own the ZS250GS and got a noise at the motor like something loose inside. it sound hardest in idle and cold, otherwise i noticed that the camshaft has some signs of wear, because I can not adjust properly the valves, so I thing the anterior owner run the bike w/ out oil.:grr:
wen I bought they have not the noise, (or only a little), and wen I changed the oil, it was full of an sustance brown like wood flour or something.

Well, I am not afraid to open the engine and check, but I thing is bad idea because......Were can I find parts.

The question is, can I replace the engine for other similar in size with some adaptations?

Or can I found engine parts somewhere?

Help me please.

It's based on Yammie. If u had plenty $ to burn, genuine Y... parts may work.
taobao.com + agent seems the most sensible way.

Whirring noise........ could be the turbine starting up....

I hardly try to find motor parts at taobao just in case, but...I don't Know how.
Sorry.

Well, sound like randomly grinding something, but, don't affect the working of the motor. in fact run very good.

any ideas about put an alternative engine?
Is good idea open it to see what's happen?

Is my first bike in 30 years, I bought it cheap ($300.00) with the tank full :tup:. and I spend $200.00 more replacing back shock (used), brake cylinder, spray paint, ignition coil and some durabond.
I really enjoy this project, but I am a little worry about this noise, is not good. I really want to find any relatively easy solution, but I start to loos my illusion at this project. Well, still having some hope.
There some pics.

He means Yamaha. The engine is very similar to the Yamaha XT225, the TT-R230 and the TW200.

When you changed the oil, did you clean the oil filter in the side of the engine? The filter must go back in correctly, or no oil will get to the camshaft.

Yes, the head look oiled, but the sound come mostly from the bottom.

I see some affordable Lifan 200cc motors at EBAY.

Are compatible?

Can I swap w some adapt?

Were can I find specs, measures?

Thanks.

The Lifan motors on eBay are designed to fit a Honda application. You might be able to make one fit, but it will not be simple.

Where do you live?

South Florida.
Do you know any Supplier close?

I believe there was a supplier in Florida, but I think they've closed the shop.

Taobao is a source for parts, as Humanbeing indicated. Use Google Chrome, visit www.taobao.com and allow Chrome to translate automatically. Search for ZS250GS, and see what appears.

I translated from english (well, from Spanish to English first) and to Chinese w google and c/ paste at taobao....and it works. i suppose That the agent in china is other steep, and the delivery time too. But I gona open the motor to see what's wrong, and send you some pics.:thanks:
