Dear all! I have a 400n, that badly needs all four of the muffler seals replaced - one of the PO's changed those for some asbestos type rolls, but they don't do their job properly anymore, and the bike smokes, where it shouldn't - from the muffler joining points. I was to fabricate some new ones from baked bean tins and RTV, but turns out, the place, my brother works at uses graphite seals of all shapes and sizes and he could get me some. I tried to search for the seal sizes high and low, but could not find anything, neither for the front nor the silencer side. Does anybody has got some at hand, that could give me some measurements - width, height, length? Imperial or metric does not matter, your choice Thank you! Gabriel

Hi szabgab, what is RTV ? Hi Stevie, sorry for the confusion - it is just ordinary heat tolerant silicone

Great info, thanks! It looks like, the seals are 5 ,mm thick, as the downpipe is 40 mm and the silencer 43-44mm dia

Update now I'm awake... I have an old front seal that measures O/D 44mm-I/D 38mm (the 44mm could well be crushed?? but not as much as 45 as I suggested before) but the old silencers I just measured are 43mm pipes so that will be your I/D for the rear. The front one is 20mm long, I believe they are both the same front and rear. 6mm wall thickness (i.e.) 44-38 x 20 long front and 49-43 rear I'm sorry I can't help more, and I stand corrected if theres an expert who knows more.
