I think they were 250's too :wink: .

Have you changed your coolant? Does it have a theromstat? Is the cap's spring pressure appropiate? And signs of running too lean? Are the hoses OK?

We here at Chinariders are a little leery or watercooled Chinese engines... We prefer it when the Chinese keep it simple, like air. They have not screwed up air. :lol:

I dont have the information to go ahead and disassemble everything but what do you mean by runnin lean? Im working on it right now im going to try to clean the carburator

So can someone help me with the engine diagram? And were to buy parts?

So no, do you guys have specs or diagrams about the engine?

There are not many of the liquid cooled ones around. Running lean means that the air/fuel ratio is not correct. Too much air not enough fuel. A carb clean may help that.

I would confirm that the coolant level is correct and that the thermostat is opening. Maybe the waterpump is not working.

I checked last night and the card is dirty and it doesnt keep steady rpms, and for the radiator i was told that the coolant hose is not tight correctly, is this engine based on a cg 200 honda engine?

I've never seen a liquid cooled cg engine, but it could be. If you manage to get ahold of an air cooled CG200, it would be a much better choice.

I see similarities to the air cooled versions. If it runs and you can correct the issues it should be worth keeping that engine.

I would check all the hose connections and clean out the carb. Also making sure the carb to intake manifold connection is good.

Well i did some research and is based on a honda cg engine, today i cleaned the carb and we took it offroading and it did good but the pipe got red after awhile i dont know how to adjust the carb, and for the radiator it spilled antifreeze when i was riding it so i stoped and the fan didnt turn on, i fixed the fan but lets see if the temperature thing works and turns the fan on, any idea what kind of oil it uses?

How much turn does the air and jet screws in the carb have to be?

I would set the screws at about 1 1/2 turns out and then adjust from there.

Maybe you need to install larger jets in the carb.

Oil. 15w40 diesel oil works well and is cheap. Shell Delo etc. Walmart carries it.

Alright ill set the screws 1½ open and how can i change the jets if there already preset? Is there a place where i can view service repair manuals?

15w 40 !? I thought it was 10w 30 for gasoline engines

Can you wire the fan on a manual switch so you just turn it on and leave it on?

Yes im planning to do that but i want to see if it turns on by itself now, i just blew a fuse, any idea what kind of fuse it uses? It had a 15A but it was broken then replaced it with a 10A then there was a faulty wire wich blew my fuse, i dont know what kind of fuse i should put
