What is the method or How to improve Royal Enfield Thump?


QI have royal enfield electra twinspark uce
2010 model
I removed & changed the bend-pipe.
I have installed the free flow silencer but there is no original thump.




Ans: About 80 % of Enfield buyers do so because they are in love with the sound. However as exhaust emissions get tighter by the day, so do the noise limitations. In order to achieve both and do so comfortably, the modern Enfield has an engine of unit construction (engine & gearbox in one unit).

Right from the design itself, it is supposed to provide more refinement (meaning less noise and vibration). So if the engine itself produces less noise, how can you get the old thump just by changing the silencer ?

  1. sorry mate but the UCE/AVL engines don't give the thump CI engines used to give. any CI engine even without a heavy crank had that thump in it. CI + short-bottle silencer + heavy crank = dream machine

  3. You can increase the thump by using either a short bottle or a goldstar ( goldie )silencer. In case if you are going for a short bottle silencer, if you want the loudest sound, get an Indore short bottle, or if you are looking for a little mellowed thump then get the Chennai short bottle. You can also try the goldie silencer, it produces a thump with a nice bass note, however I personally would not recommend a goldie, as it's a free flow silencer without any baffles and you would feel an immediate drop of the low end torque, which happens due to lower back pressure of the exhaust gases. I've all the three silencers on my TBTS, and chose the Indore short bottle, which has a thump nearest to that of a CI engine... but nothing can beat the CI dug dug thump ! Hope this helps :-)

  5. @Harpreet Singh Soni : You need to take out the cylinder head and cylinder kit...
    if there is play in the crank then you'll have to take it to the "Kharaadiya" to set it and after that it'll work good...
    Some garaaris will also need to be changed, that your mechanic will tell you.....
