spiderbox GY6 150 cc smoke comes out of hose
 

smoke comes out of hose coming out of valve cover; what is wrong ??

Nothing!!! That's normal

thanks; thats a relief !!

It's your crankcase ventilation-The engine has to breath!!! It should only smoke after running real hard and not at start-up. Lots and lots of thick smoke can be a sign of engine problems -- Also if it drips oil too much you can elevate the hose so the oil runs back into the valve cover.
