suzuki250 Posted September 29, 2015 Report Share Posted September 29, 2015 (edited) I’m looking for a nice exhaust silencer for my Villiers project, I’ve had a look around and all I can find are 4 stroke silencers?

old trials fanatic Posted September 29, 2015 Report Share Posted September 29, 2015 Not difficult to make but if you dont fancy that then just use a WES rear silencer that fits the gap and have a new bracket and inlet tube welded on 1 Quote Link to comment Share on other sites More sharing options...
totalshell Posted October 1, 2015 Report Share Posted October 1, 2015 fabrication time as above. either make one or have someone mod a new wes to fit.. the joys of pre65.. getting the length of the pipe from barral to silencer is critical to performance..

old trials fanatic Posted October 1, 2015 Report Share Posted October 1, 2015 Just measure other peoples. Choose the successful ones preferably. Also the dia affects power delivery. Quote Link to comment Share on other sites More sharing options...
laird387 Posted October 1, 2015 Report Share Posted October 1, 2015 Hi, There was a firmly held impression that the best way to extract controllable bottom end power from a Villiers was to fit a silencer with the same internal capacity as the complete cylinder plus crankcase, the length of the exhaust system was considered to effect the revs at which most power would be available.

charlie prescott Posted October 1, 2015 Report Share Posted October 1, 2015 (edited) Hi Guy's. Deryk. That is why we fitted the old "Peco" silencers and a short front pipe, for the exact reason as you have stated. I believe a copy of that system is available from a supply in China so I am told. Update today 2nd Oct. Not made in China, but made on the Wirral, by Cybox, that used to be the old Peco. They make one off, or batches of exhausts to pattern, so here is your chance. They may still have the old Villiers James pattern? There you go only took me an hour to find out. Regards Charlie.

trialsrfun Posted October 2, 2015 Report Share Posted October 2, 2015 Most of the recently built Villiers powered bikes have a longer front pipe usually looping round the frame down tube then meeting the silencer at the rear of the cylinder with the silencer over the gearbox. The original exhaust fitted to the Greeves Scottish had a long pipe coming over the head before crossing to the right hand side of the bike at the rear of the tank, these bikes were said to perform better with that exhaust because of the long front pipe.

charlie prescott Posted October 4, 2015 Report Share Posted October 4, 2015 Hi Guy's. Nice run of snaps Deryk. and not a siggy in site. Must have been before the pressure was put onto him to win every trial. Have you noticed how low the bars were on that bike? putting more weight over the front wheel. But the power from the motor with the "Short" exhaust system fitted was still enough to lift the front wheel in sections. Regards Charlie.

trialsrfun Posted October 4, 2015 Report Share Posted October 4, 2015 And not one of them fitted with a Peco exhaust, the Greeves front pipe being longer. Villiers Services have 1 3/4" front pipes for both the round iron cylinder and the alloy square type. Quote Link to comment Share on other sites More sharing options...
