As a well-known motorcycle throttle cable suppliers, Huafeng is an expert in the industry, here to provide you with solutions for maintaining and inspecting the throttle of motorcycles. However, before we do it, we need to make prerequisites and preparations. The inspection and maintenance of the throttle requires us to turn the throttle handle to check whether the return is good. If it is stuck or cannot return, it should be maintained.

First, remove the mirror. Remove the oiler seat, remove the throttle cable and the oiler. Secondly, add a little lubricating oil to the throttle cable, and apply a little lubricating grease to the oiler. Finally, install them in reverse order. Pay attention to this step, the throttle cable should be cleaned and lubricated once every 2000km.

In addition, if the requirements are not met after adjustment, the adjustment solenoid valve on the top of the carburetor must be adjusted or replace a custom motorcycle throttle cable. When adjusting, first pull out the dust cover, turn the adjustment solenoid valve until the free stroke of the throttle knob is 2～6mm, then pull down the dust cover to cover the adjustment solenoid valve.

For two-stroke engines, after adjusting the free stroke of the throttle handle, check whether the mark on the oil pump control lever is consistent with the mark on the oil pump body when the throttle is fully opened (the error is within 1mm). normal). If the marks do not match, loosen the lock nut on the oil pump control cable, adjust the adjustment nut until the marks match, and then tighten the lock nut.

If you need to disassemble the oil supply system, don't forget to release the pressure first. The method is to open the fuel tank cap, release the pressure in the fuel tank, remove the fuel pump connector, start the engine, and let the engine run at idle speed until the engine stops naturally. If you can't start the engine, disconnect the injector harness connector, connect one end to the ground (earth), and use a jumper wire at the other end to contact the positive electrode of the battery for a long time. Yes. 10 seconds to release the system If the above two pressure relief methods can not be achieved, you can also use the method of removing the oil pipe to release the oil pressure in the oil supply system. If you use this method to relieve the pressure, you need to find a clean cloth to cover the removal part and absorb the gasoline, so that the pressure will not spray the fuel anywhere.

In addition, when checking the fuel supply system, turn off the electric door lock switch and remove the battery negative wire to prevent accidental sparks from igniting the gasoline.

When removing the electric fuel pump from the fuel tank, do not energize the fuel pump. Fuel pumps cannot be tested under dry load or underwater. Do not connect the positive and negative poles reversely. Otherwise, the service will be shorter. Life.

When removing the oil pipe, make sure that no foreign matter enters the oil supply system, contaminates or blocks the oil supply system. The oil pipe joints of the refueling system are specially designed and require special care when disassembling. The used O-rings, gaskets, pipe clamps, gaskets, etc. are all disposable accessories and must be replaced with new ones to ensure that the oil supply system is sealed and does not leak oil.
