    Default Change of silencer to short bottle at first service - is it fine?

    Hi All,

    I have purchased new Royal Enfield Bullet 350 UCE last week. Have done around 300 km now and will get the first servicing done at 500 km - probably within next 2 weeks.

    I want a louder thump note and have almost decided on short bottle silencer.

    The question is - Shall I go ahead and change the silencer at the time of first service itself, OR shall I want for more time (say till 3 months to complete - at the time of second servicing)?

    Best regards,
    Anand

    Its a brand new bike brother! I would suggest you to wait for some more time!
    If i would have been in your place, i would have thought of doing it in 3rd service..

    Ya exactly....u need to give its own time to settle....wud suggest to run for the next 2k kms in the same. Lot of engineering been done on silencers. speak to 9080999666 seshan about silencers. Refer my name and he will tell u the science behind it

    wait for atleast 6000 kms before changing the silencer. The backpressure from the longer silencer will come handy in running in the engine properly.

    they made a change in Silencer of all new Enfield Bullets because Enfield india want to ensure their bikes are adher to the norms of new emmision norms
    (noise and smoke)

    you know how good our mamul indian traffic police
    and you know it voids the norms

    IMO, the soonest you can do it will be once the warranty period is expired. Do not take the risk of modding anything during the warranty period.

    Like @JD says, give sometime to run.

    Default Thanks Pratheek, pratheekkunder, ramesh, jd666, msn1 and aargee

    Thanks Pratheek, pratheekkunder, ramesh, jd666, msn1 and aargee!

    I will take your advice! I will not change it for next 6 months at least. BY the time I would have covered 5000 km or so.
    Or may be - I will wait for warranty to get over i.e. 1 year. That way running-in will be fine!

    Thanks for all your inputs.

    Best regards,
    Anand

    Default Short bottle silencer for STD 350 CI

    Hi all,

    I have a STD 350 CI 2009 model that has clicked 4500 recently and I have run in properly with the stock long bottle silencer with the "C" type bent pipe.

    I was pondering over the thought of using a short bottle silencer as one of the bulleteers mentioned that this would free up the engine as the long bottle one is very restrictive.

    Here are my queries

    1) If I go for short bottle silencer, do I need to change the bent pipe as well. I would prefer to keep the present bent pipe given a choice.

    2) What brand of short bottle silencer would you recommend. What are the things that I need to look for ( with baffles, freeflow, glaswool type)

    3) Will there be any retuning of the carburator required after the change

    4) How will the change to short bottle silencer effect the torque and top speed

    5) Will there be any drop in the average that I get per liter of petrol

    6) Will this cause any exhaust valve damage in the long run?

    Regards,

    Srikanth
