What does 'Pre-unit' mean?

That warrants a dog turd through the letter box, that does.

 

Thus spake Roger Hunt () unto the assembled multitudes:

Given that said incident took place in 1976, that's a bit of a missed
opportunity. Anyways, I've got over it and moved on ;-)

 

Actually, wasn't the Evo engine the first unit Harley lump?

As an aside, technically modern Guzzis have pre-unit engines, as do
most BMWs.

 

Summer of '76 was when I discovered that sweating through leather
is preferable to gravel-rash on the back of hands, fingers, elbow
and various other body parts, and a dislocated thumb.

Good ... moved on to petrol bombs do you mean?

 

1948 DKW-based 125S. If you want an actual Hardley, 1952 K model, ancestor
of the Sprotstre.

And other modern production bikes, such as Enfields, Urals, Chang Jiangs...

 

And yet they managed to keep going backwards. Why on earth did they do
that, I wonder? I suppose it was too modern for the Hurley owners of the
day, moaning and blowing smoke into their beer.

 

Ah. Someone once gave me a book about Harleys and their history. I'll
have to dig it out and actaully read it.

 

Harrumph. Comparing that load of rattly aircooled push-rod heaps to
the modern Guzzi.

 

Where and who was it? I live off Portland Road.

 

Thus spake sweller () unto the assembled multitudes:

I lived in Vale Road, Portslade at the time. I don't recall exactly where
Imola 500 was, and haven't been in that area for *years*, but it was
somewhere on the border between Portslade and Fishersgate I think. Possibly
Church Road or thereabouts? Memory dims a bit after 30 years ;-)
