Solo Odyssey 40/2 with stock Solomatic clutch pulley.

So a bike I've always wanted to work on came through the shop the other day, it was a Solo Odyssey 40/2. These German made mopeds are stock "watercooled" that have a static water jacket, case inducted, and resemble a Batavus m48 meets a Peugeot 103 engine. They were designed by the Solo brothers who I like to call the "MORE LIKE YOLO BROTHERS". The Solo motors come in 1 and 2 speed models as well as some variated models. I'm assuming the 2 in 40/2 means it's a 2 speed. The interesting thing about the 2 speed is that the first gear clutch is on the crank and the second gear clutch is in the rear pulley. As far as I know it's the only US model of mopeds to come with a factory stock clutch pulley. I think the best application for this would be on a stock moby, stock 103, or perhaps a batavus m48 for some extra kick.

Here are some cross-sections and a page from the manual with seals and bearings if you need that info.

There are a number of other odd things about this bike. It uses a 10mm round top bing, it has a handlebar lever that controls whether you can pedal backwards or not, and the stock watercooling. P.S. from what I gathered the cylinder/head takes 50/50 antifreeze mixture. Here are a few pics I took of the bike, of course I had to take the clutch pulley completely apart :)

 I really dig the seat.

 The circle indent is the plug to refill the coolant.

 2nd gear cltuch pulley

 1st gear clutch on the crank.

 Bosch ignition.

 This is the cable controlled lever that stops you from back pedaling. The lever is on the throttle control side where most bikes have the choke lever.

 This thing is pretty heavy.

 15 teeth.

 I just tapped the outside with a mallet for a while and it cracked. There is a rubber ring gasket around the whole half so be careful not to mess it up.

 Clutch arms.

 Fairly easy to spread open.

 Clutch pads.

 Not pictured is the same sized shims that go underneath these gears. 

 Dont forget this gasket.

 Tried to pull the front clutch to see the starter clutch and everything but the puller seems super small and we didnt have it. The CEV puller was too big and it was the smallest we had.

 Intake looks pretty small but I like the rubber ring gasket.

 Odd shaped plate.

 Induction.

That's a new one! ps this bike came with a 58 jet in it.
