Silencer modification
« on: May 08, 2011, 01:16:53 PM »
        I searched through hundreds of threads but couldn't find this subject so if it's already been discussed sorry about that.

I'm sure others on here don't care for the way the silencer sticks out almost to the rear fender :) and it's straight instead of following the lines like a 250 but is there a way to make it so the silencer just barely sticks out past the side plate?

I don't know if moving the bracket on the silencer or cutting part of the pipe on the silencer so it's a lot shorter but doesn't hurt the performance of the silencer I think it would look a ton better more up to date or maybe fmf or pro circuit could modify the silencers so they barely stick out.

          Ok good news I found a solid welder that is going to cut my 304 silencer off so that it sticks out about 1/2" past the number plate and he's putting thicker metal on the inside so I can have allen heads (countersunk) so I can repack the silencer and the allen screws will sit flush it should make the back of the bike look a little better more modern and less prone to destruction in the case of a crash, I will get pics up when it's all done.

        I was wondering about the performance aspect of cutting one down and I found a welder that is cutting it down and welding metal on the inside of the silencer so he can drill and tap it with the same type allen head bolts that are used on the back end of the silencer so I can use it over and over again repacking at will so it should be done tomorrow I'll post pics if it happens.

      My silencer just came back from the welder and he put screws in the front so I can repack it when the time comes, he repacked this one with the packing I brought over to him and this silencer sticks out about 2" past the number plate it's going to look good on there.

looks similar to my spes, except i didnt have anything welded to it.  just used rivets for the end cap.  you may be suprised as this silencer may work a little better for some applications.

Sniper,
The silencer looks nice! A general rule, the shorter yields more bottom, the longer yields more up top (with added heat).

        Thanks guys and I was fortunate to see a welder for hire sign in front of this guys house and he's one of those guys that has to do it right so he really put a lot into doing it right for a grand total of $30 which is awesome for a silencer that will look better due to it's length and will be harder to damage if it flips over backwards then you have the performance that was mentioned and I'm ready to roll.

Thanks :) I can't wait to get her mounted and take it for a spin not to mention a few pics.

Roost daddy I wanted screws in both ends so I could repack it anytime it needed it and hopefully I can get years of use out of it due to that.

       It does look a lot like a works silencer :) I'm sure glad the welder knew what he was doing because the night before I kept having nightmares of booger welds and the wrong length lol.

       I might break out the dewalt cordless and give it a nice even polished look :)

         I haven't put it on yet but will in the next day or two and give you the most honest review of how it sounds that I can along with pics. I have to take my cycle endorsement test so I have the forest approved silencer on it for now until the test is done just in case it's loud.
