How can I know the motorcycle oil pump?

My motorcycle is a silver only 100, four stroke car, recently a little burning instability. I wonder if it's the oil pump. Who knows how to know the oil pump?

Answer:

Open the cylinder cover, ignition, see oil poured on the cylinder top, slightly accelerated a little oil on the Bay on. (be careful not to gush to the outside, this is exactly the effect) of oil pump is good. The oil pump in the wave at the bottom of the box, after the oil filter cylinder to pressure on the top of the net, if the oil plug, first check whether the oil is too dirty, if there is not enough, two are normal, it is necessary to replace the oil pump.
The cylinder head four nuts is a yellow pad with a copper pad, is generally the lower right corner, it is the oil check screw, take it off, start the engine soon after oil runs out, if there is no oil outflow or outflow rarely, that oil pump may be a fault or is the blockage of the oil pump, but the general problems can cause the camshaft, rocker arm, cylinder wear, plug, ring, will not affect the ignition instability, if it is bad to can affect the ignition instability point, the parts would wear a different sound. If the ignition is unstable, it is better to find the reasons for the carburetor, the sealing of the valve, the valve clearance, and the spark plug.
1. remove the valve cover on the head of the cylinder and start the machine. No oil runs out in 10 seconds. That is the problem of the oil pump. Otherwise, it is normal2., you open the valve cover, and then start the car to observe, a little bit of oil, to see if there is no oil splash from inside, if not, that is, the oil pump work is not good.
