Hi everyone.  Silencer had been dismantled before I ever saw it.  Baffles fit on the long rod attaching to the cone, that is ok.  But the 'Primary' baffle {if that is what it is) was just loose in the silencer.  How is it secured?  Am I missing a part?  I have been reading through all of the blogs and every unit seems to be different.  No pyramid spacer that I can find, although I have boxes of nuts and bolts it could be in.  What does it do?  Do I need it?  Everything needs the oily gunge removing, working on that.  Thanks.

Here's my D3's.

The rod which the secondary baffles fit over is welded to the 'cheesegrater', which is attached via a bolt through the silencer body, near the exhaust mount. I can't tell if your rod should be attached to the tube or not, but don't see how it would work otherwise. Also, it looks to me that the front end of the tube sits just behind the exhaust pipe and is held by the tight fit.

To clean the «censored» off, I  used a paint stripper blower in the open air, be careful with the silencer body though, or you will blue it.Baffles.JPG

I didn't realise (C) rud was a swear word, I'll try 'oily excrement' next.

Ha ha.  I have said a lot worse trying to build this thing! I saw your post and wondered if they were similar styles. But now you have mentioned that the rod should be welded to the tube baffle it becomes a bit clearer, and quite obvious now I think about it.  I should have placed the circlip at the other end of the pipe for the photo, I took it off there, guess it tightens the pipes together.  Any idea about needing the Pyramid Spacer?  I can easily buy one anyway.  Thanks.

as you now know the rod should be welded inside the silencer which then holds the baffles and the end cap on

But you also have the wrong silencer, that one is off a D3
I have a D1 mongraal bike with mostly a D10 4speed engine I started off with a D3 silencer but it had a bad dead zone above 3000 rpm I fiddled about with the carb jetting for a while and then thought I would try a D7/D10 silencer
which cured the problem completely
the Exhaust on a 2 stroke make a big difference
D7/D10 type below

Are you sure, Mike? This is off my 1956 D3, original as far as I am aware - but after 60 odd years who knows?

Doesn't show the fishtail end, but does show the effect of over enthusiastic heat gun exposure...whistle

This is the photo I posted a while ago.  Now got the 'pyramid spacer' and 'sealing ring'.  But where exactly do they fit?  Confused.

Yeah, it seems to be a mish-mash of D3 silencer with a D10 end cone.  They must fit together somehow.

It doesn't look like a D3 casing to me, neither does the main baffle. The rod would be welded to the end of the baffle on a D3, then the rear baffles fitted to that (inside the casing). The sealing ring between the casing and the fishtail, then the cone nut holding the fishtail to the pipe - which means the main baffle has to be fixed somewhere. On my D3 is is via a bolt through the casing and baffle near the mounting bracket.
