motosolex Posted April 26, 2014 Report Share Posted April 26, 2014 Hi, While sniffing around on the web, saw were a bloke re packed his stock TY175 silencer, in the spark arrestor as in the photo. Any ideas on this and whether it will reduce the noise footprint for us living in urban areas. Thanks Quote Link to comment Share on other sites More sharing options...
feetupfun Posted April 26, 2014 Report Share Posted April 26, 2014 The standard end muffler/spark arrestor on the competition model TY175s (prefix 525) is noisy no matter how well it is repacked. The WES end muffler is much quieter and lighter. A super quiet alternative is the end muffler from the Yamaha JC and JE models of the TY175, which combined with a rubber snorkel in the top of the airbox, made it an amazingly quiet bike, and meet the strict road registration noise level requirements of the time. The Ty175JC model (prefix 1N4) was sold in Australia and a similar model the TY175JE was sold in some European countries, and their mufflers are sometimes advertised for sale. The WES muffler is not quite as quiet as the JC/JE muffler. The JC/JE muffler is bigger and heavier than the muffler from the prefix 525 bikes.

feetupfun Posted April 26, 2014 Report Share Posted April 26, 2014 the TY175 JC/JE muffler also works well on the TY250, but needs the inlet tube shortened to fit the TY250 Quote Link to comment Share on other sites More sharing options...
