Royal Enfield Classic Fault Codes
Royal Enfield Classic motorcycles have engines, which are made up of many different parts. These parts must work together in order for the engine to function. A problem with one of the parts can make the engine not run. There are many different parts that make up an engine. The following royal enfield classic faults are the list of some of the parts of a motorcycle engine.
One of the most common issues with Royal Enfield Classic motorcycle electrical systems is a clogged battery terminal. This can cause your ride to start having issues with the electrical components. Discolored terminals are often caused by a build-up of corrosion. This will prevent electrons from flowing properly, which reduces your ride’s electrical performance.
Royal Enfield Classic Faults :
Another drawback that may occur along with your bike engine could be a blown gasket. this will cause your engine to overheat and presumably crack the cylinder heads. during this case, it's best to require your Royal Enfield Classic bike to an expert mechanic to possess it verified. Another common drawback is with the carburettor. The carburettor is that the a part of your bike that mixes air and fuel to make the combustion required to power the engine.
We have listed below a few basic checks in case your motorcycle is not functioning. If in case the problem is not rectified after these checks, it is necessary to get the motorcycle checked by a Royal Enfield Authorised Dealer / Service Center to rectify the problem and to ensure trouble free performance.
Common Royal-Enfield Problems :
Symptom | Observations | Check for / Remedy |
---|---|---|
Engine does not start |
1. Ignition/Engine stop switch is in OFF position 2. Very low / No fuel in the fuel tank. 3. Lights / horn very dim 4. Electricals not working 5. Engine Cranking but not starting |
Switch ON Ignition / Engine stop switch Turn fuel tap to reserve position / Fill Fuel Weak/Discharged battery. Replace Battery 1. Battery completely dead. Replace battery 2. Fuse Blown. Replace appropriate fuse. Note: If fuse blows again, contact Authorised Service Center. Spark plug Cap/wire disconnected. Reconnect. |
Engine Starts BUT shuts off immediatley | Engine shuts off as soon as throttle is closed. | Idling RPM setting in Carburetor is disturbed. Reset the
Idling RPM screw in Carburetor. Carburetor Flooded. Shut off fuel tap, gently tap Carburetor bottom and reopen fuel tap. Check if flooding has stopped |
Engine Misfires & Runs Erratically / Stops | 1. Typically happens after a Refill / Adulterated /
Water in Fuel 2. Motorcycle driven in Low gear / High RPM / Crowded places for long time. |
Drain out entire fuel and Refill with fresh fuel from a reputed
filling station. Excessive Engine temperature. Switch OFF Engine and allow to cool down. |
Poor Pickup | Engine RPM raises improportinately to motorcycle speed Rear Chain excessively loose causing chain to slip on Sprocket. |
Clutch is Slipping. Check for sticky clutch/ clutch not having
any free play. Adjust Rear chain to correct tension. |
