For the type of automatic motorbike that has problems with heavy traction, or even the engine suddenly becomes heavy, it can be caused by a small part damage in the engine injector area.
The position on this problem is located between the injector and the intake manifold seat or on the Throttle Body.
Fuelpump is a component on an automatic motorbike or injection that is planted in the fuel tank to pump / flow fuel to the injectors, so the way it works is to pump fuel from the tank to the injectors through the injector hose and cause a pressure which eventually sprays. and it is burned in the combustion chamber on the motorbike, so if this is a problem the pressure is not maximal and this is what makes your motorbike feel heavy on the pull.
The main cause of the above is that the dirt stuck on the filter becomes dirty, all you have to do is clean or replace the fullpump rubber, so that the engine can work normally again, because the fuel can be sprayed perfectly.
