And Today's Mystery 2 Stroke Is...?

[Quartermaster]

It is well known that you Carpedians are the cleverest bunch of motorcyclists in the Universe. I have a problem with identification and could do with some help.

 

A mate purchased a cutaway engine and he doesn't know who the manufacturer is. As you  can see, there is a distinctive insignia cast into the RH casing. I'm sure some one out there will recognise it!

Possibly a Victoria?

I don't recognise it but looks like a crown so Monarch ?  or maybe Monark ?

Nm, it's an engine from a  "Rap" crown

Is there a sticker under the wooden plinth ? lol

Brilliant CTD. How on earth did you find that out?

Yes, it says "You'll never guess what engine this is"!

Certifiable Google Ninja Start off with the premise that any old two-stroke engines are likely to still be in circulation in India and hit up those forums with some keywords

Is it a Hodaka combat wombat? :-)

I'd love to think it was Dappers! No coconut this time.

Lots of wonderful old 2 strokes in Holland that I'd never heard of or seen before until they all appeared at a classic bike show we went to when we were on holiday there . I think there are some regulations in the Netherlands which mean that classic bikes can only be ridden to and from shows ( although I might have misunderstood the point).

 

Portugal is a bit the same for odd ball old 2 strokes.

Looks like it was a college project to explain mechanics.

 

Clutch on the crankshaft - terrible design but it did keep it small. Yamaha used that design on early 250 twins, then went racing with them. At 10,000 rpm the crank would eventually break off and launch through the casings!
