Rear rack and exhaust

Tjis week i’ve only done some small things due to busy working. I picked up this rear rack from a parts fair and I thought it would suit the scoot well with the double single seats and all.

I also added an exhaust. This one came as a spare when I bought my other Lambretta. It is in good state and also came with a exhaust manifold. I had bought another manifold that I’ve already fitted but it was angled way to much and thus didn’t fit the bike. Lucky me I had another original one to spare.

Exhaust nuts

Now it was time to add the cowling. I quickly realized it couldn’t go on without me removing the exhaust manifold.

Since I had to unscrew it to get the cowling on I thought I might as well try the trick I read about in a Lambretta forum thread about using the chain guide locking washer.

I found my old locking washer, I hadn’t discarded it to the bin yet.
Cut it in two pieces and widened the hole so it could be added through the studs.
Said and done, added it first, then a spring washer and finally the nut, of course with the cowling rattling loosely close by making it almost impossible to reach the hidden nut.
Then with a screwdriver I turned one of the lips up and the exhaust nuts will hopefully stay in place. This is probably something I will have to do to my other bike. When its parked I can see a tiny drop of oil/gasoline on the garage floor. Hadn’t cared so much about it since it was such a little amount.

Engine removal

Today I took the engine out of the frame so I can more easily work on it. It looks like it’s definitely been stored in a barn sometime under it’s life since I found hay on it!

The engine also showed a crack on a stud for the crankcase cover. I saw the same on the rear brake hub, I figure some former owner must have dropped the bike while trying to change rear tire, or it was that now famous repainter.

Hopefully I can weld the aluminum case so I can rebuild the metal around the thread and if the hub is nice and strong otherwise I can still use it. Since Spanish ones are dead hard to find and Indians are mostly ok I prefer to keep my original.

The whole point of this resto is to not unnecessary throwaway stuff that actually does still work fine.

Exhaust and manifold

The exhaust is in a really bad shape. It has surface dirt and rust on it.
The battery has been leaking sometime in the past, a couple of decades ago, and it has left white marks on the engine mounts, exhaust, kick, battery tray and other things in it’s way.

The complete removed exhaust, I dont know if it is possible to clean out and reuse. There is no fracture or part missing, just dirt and rust.
