Hello Michael
                I have both exhaust pipes and nuts which I think are right for your Douglas.

If you email me I should be able to send some photos and measurements.

Regards
         Richard

glyn, it looks like you have a mid-late 50s Douglas vespa engine.  the serial is in the part that attaches to the swingarm.  The serial can be deciphered to give you the month and year of production, which will tell you which model it belongs to. happy to help once you find it.
cheers
Marc

Hi Michael thanks for your reply but I assume that the breather is clear because of the oil out the primary drive side regards Bruce

Hi Bruce,

I had bought a S6 last year and had a lot of work to find the reason for (heavy!) oil leaking.
Im the 3rd owner after the restauration and I could imagine these oil troubles are the reason the pre owners were not happy for the bike?

In the end (after weeks) I find a the mistake, the breather channel inside the 2 crankcases was blocked by a gasket with NO hole in it for the air passing through!
So the breather could not work.
Very simple but big effect!
I hope on your S6 is this okay.
I have still small leakage from the oil indicator.

Hi Eddie thanks for the info which I took notice of in the maintenance manual and made sure the flywheel side nuts were tight before I put the timing cover on pretty sure there are no cracks in timing cover but I'll have an extra careful look next time I take it off regards Bruce

Hi Bruce,
              It would be a good idea to check out the timing cover for cracks. They are prone to cracking, especially if the correct procedure for tightening the crankcase studs is not adhered to. The crankcase studs should be tightened left hand side first ( that makes sure the crankcase halves and the primary chaincase are securely clamped together). The timing cover nuts should then be nipped up just enough to produce an oil tight joint. If the timing cover nuts are tightened first, the timing cover could be taking the stress of keeping the crankcases together because the heads of the through studs are not snugged up to the timing side half of the crankcase - this also allows the timing gear outrigger plate to wriggle and eventually break off the cast alloy oil feed pillar inside the timing chest.
  Hope this is of some help,
  Regards,
               Eddie.

Thanks Bert I've only done 40 k's on the bike since I put the engine back together so I'll just have to see how it goes How well does the breather have to seal on the timing case regards BRUCE
