350 is fab little bike- little being the word, feels small on me & I’m 5’11”. Every time I ride mine I think why bother with more cc’s this does what you want. My Brother had one back in the day, zero mechanical sympathy, rev the bollocks off it from cold, never looked at oil and used and abused it . I bought mine a few years back and was truly impressed by how good it was- must have been great back in the Seventies.
Electric fuel tap, electronic ignition, cam belt and a red charging light(?) are all quirky for a bike of this age.
