Motorcycle engine fever is serious
Modified cooling system, there are oil and water cooling, hands-on ability is not strong, then do not recommend this step.
Carburetor mixing ratio is too thin, the engine will overheat, see the spark plug has not been ablated.
First check the next is forced air-cooled or natural air-cooled, (pedal is mandatory, the general ride is natural) forced air-cooled look at the fan is not broken, (bad replacement like)
The engine burns up, and if it overheats it will damage the engine.
