Part 7 - Silencing the Noise

Silencer with rivets drilled out.
According to two of my neighbours, my TS250 is too noisy. To be honest they are probably right as there is clearly no baffle material left in the after market silencer. The silencer is riveted together at each end and is clearly not designed to be serviced which is a shame. On the other hand, it has never stopped me before.

Firstly after removing the can from the bike, I removed the end plate and drilled the rivets holding the end cap in place. On this particular can there had been some damage on the endplate on the engine end of the silencer. It made sense therefore to remove this end and make the repair at the same time. Given a free choice, I would have taken off the other end as it allows the packing material to be packed tighter at the engine end where the baffle material gets the most abuse.

Once the endplate was off, I proceeded to remove what was left of the old baffle material. This was in a very poor state and it took a lot of effort with old hook ended brazing rods to get it all out.

Once cleaned out, a bag of 2 stroke baffle material from eBay was packed tightly into the silencer and the end cap was riveted back on.

Adding new baffle material.

It doesn't look it, but it is very tightly packed.


Pop in the new pop rivets and all is good.
Easy really. The bike now sounds great. To be honest it is still noisy, but who cares, it sounds great.

The exhaust used almost all of this bag of baffle material. Less than £5 from eBay.
