Liking the short silencer. I recall back when I had mine there were 2 lengths (or more?) of silencer and mine had the short one which had a terrible rattle when I got it - turns out the 'baffle' which was basically a short tube with a metal spiral around it was falling apart - so I took it out completely leaving just the hollow can. As such it was quite loud, my parents used to say that at night, they could hear me coming home from halfway up the hill. Here's an old pic. just because; I suspect yours will sound even more fruity given the 450cc engine.
I have both a short and a long silencers for my 450. The long one is quiet but subdues the performance; the short one has a sprightly bark.
Got the wheels back and after loads on honing, got the new brass bushes and swing arm pin installed. Now settling on the idea of a custom rear light mount and even though I don't need indicators, I want to add them just so I can be happier that car divers will see where I intend to go. After multiple comments from the forums, I am now waiting for a glass fibre rear mudguard that I can trim around 4 inches off and have the number plate mount up higher.
I trimmed mine down a few inches (see above pic), not because I wanted to change the look specifically but because, when I got it the mudguard was cracked around the lower mounting holes so, rather than try to repair it I just cut it off at that point. I have to say it did look better with the shorter mudguard though.
