That is a great weapon, and the terrain looks magnificent. Your bike is a credit to you.
The silencer modification is interesting. About 30 years ago, there was a fad here to add a VW Beetle tail pipe as an extra silencer and, it was said, to improve torque slightly, with the extra length of the exhaust. I had one on my XR 250 - the best trail bike I ever had, but it did not sound like the Triumph with its Supertrapp - so you may begin a new trend. A Scorpion may fit, though, and save much weight.
Yea, it's not the adventure bike I had planned, but I was running in some pretty rutty stuff that day. I dragged the bottom over a sand rut and it pulled the silencer back…causing quite a ruckus…sounded like a dragster for a moment. Once it cooled off, I just lined it back up and the spring pulled it back into place. But it was rather exciting when it first happened. I'm going to have a look and see if I can extend the skid plate back just beyond the front of the silencer...
A high level exhaust and panniers don't usually go together, and ruts can be a real pain, as you will know only well. Your suggested solution may well work, though: good luck with it. Quarter inch alloy plate, perhaps, be strong enough to protect the silencer?
I'm really thinking only .125 aluminum…it just has to extend beyond the front of the silencer so that it doesn't catch anything it might get dragged over by accident. Again, just mainly wanna stick to fire roads…nothing black diamond….
That should be easier to fabricate an extension plate with: one eight alloy in American or British measurements? I have not come across 'black diamond' before but suspect it means enduro- type going, needing long travel suspension and knobblies.
