BIKE

  • ENFIELD CLASSIC 350 2013 Model
  • ODOMETER: 14000
  • One and half year old
  • Oil changed one and half month before general servicing.

There is a particular sound from the engine while riding it in traffic.

Something like "cut-cut" or "tick-tick" you can say.

1st problem : In heavy traffic situations the engine gets hotter, and the sound appears in engine.

2nd problem : At the same time if I stop at signal and the headlights are ON the engine automatically turns off.

I showed it to 3 mechanics in Pune
The first time I encountered the issue I took it to Bullet Guru in Pimple Saudagar - He told me that the connecting rod or the piston might be the source of the sound and that he'd have to open the engine. I didn't proceed.

The next day I went for a ride and drove around 60kms with little traffic and there was no sound.

2nd mechanic in Wakad, Rajesh Automobile he asked me to change the silencer and that there was a problem with the engine

3RD - Kunal Bike Works in Viman Nagar who diagnosed it as a "problem with auto tension system in the engine or with piston"

What could be the issue?

There are several places you can get a ticking sound.

Chassis

  1. Engine RPM Cable - The cable can kink or begin to backout of the cover and a ticking noise associated with engine speed may be heard.

  2. Speedometer/Speedometer Cable - Kinks, lack of lubrication or cable slowly backing out of the speedometer housing due to ongoing single cyclander vibration can create a ticking noise associated with kph/mph (aka how fast you are going)

  3. Drum Brakes - If it is a 'cut-cut' sound and not a 'tick-tick' sound, there is a possibility of a warped drum, it's very, very rare but I've seen it once or twice. The brake shoes would rub the drum once a rotation (perhaps) and create the 'cut-cut' sound.

  4. Wheel Bearings - (low probability) Wheel bearings could be going bad. You may hear ticking. You can test play in the bearings by putting the bike on a stand grabbing the front wheel. Push and pull the wheel laterally to the forks. If there is play in the axle, replace the bearings.

Engine

  1. Valve Gap - you pushrods and behind an access plate at the base of the cylinder you can find an adjustment for the pushrod. It's a simple locknut on a shaft. Simple to adjust. No parts necessary. It's a component of standard maintenance. It will make a ticking sound comping from the head or the small cover I described. It will be in time with your RPM's.

  2. Primary Chain Adjustment - you have a transimssion that is driven off the crankshaft by a primary chain. Similar to HD and old Triumphs. This chain is hidden by a cover on the left side of the motor. There is a cam to adjust the tension of the chain. Easy to resolve. A component of normal maintenance. Will make a slapping sound, perhaps a 'cut-cut' sound, it will be coming from the bottom left side of the motor. Due to the way the chain would 'slap' up and down based upon force, RPM, etc it may not seem in time with the motor or the road, at times. Depending on the RPM and what not.

This is a common Problem in Enfield as Ducati kIller said.

The Above is the primary reason for the sound, they expand in heat and start to make that noise.
