front silencer and rear silencer are completed rotten! :(

[bernardofeio]

Hello

I’m making a cleaning and painting operation to my R 100 GS and last night while disassembling the rear mud guar I notice that the front silencer and rear silencer are completed rotten!



The front silencer can not be assembled (is broken) and the rear has so many holes that I will not have the courage to assemble it again…

So since I’m very low on money what is my best option? Should I substitute the front silencer with a V tube? (do I loose any power?)

Does any one have used front and/or rear silencers to sell? I need a cheap solution to put the bike rolling…


Thanks in advance

On a paralever GS you have:

1). The two front pipes - downpipes

2). A collector box or (Y piece)

3). Silencer at the rear

In original trim

The Silencer is stainless - I am surprised that it is no good, unless the brackets have broken off or a weld has split - expensive to replace

The Collector box is chrome plated and rusts from the top - expensive to replace - a cheap alternative is a Y piece - £100

The front down pipes are mild steel

Which do you need - all three?

I can make some photos of the rotten stainless steel rear silencer to use as a case study…

The bike was 140 000kms

I had to replace my rear silencer last year. The baffling had blown out (probably caused by having a Y piece fitted). I fitted a Keihan silencer - cost around £350.

The cheapest option if your collector box has rotted is to fit a Y piece, however there is a loss in mid range performance and the bike will run beter with a collector box. A new collector is around the £200 mark. a new pair of stainless downpipes is £163 from Motorworks.

still looking for center box BUT I've had one patched and welded before, still going 10 years later

Collector boxes often come up for sale both here and on eBay. Folk replace perfectly good ones to go down the Y-piece route only to find out later that airheads run best with collector boxes. I think I paid £15 for my last one so it might be worth waiting a bit to see what comes along.
Good luck
