I remember the first Kettle I bought, complete clean with an MOT and running £125, second one with a engine tuned to as near as mattered TR750 spec and Allspeed expansion pipes but very tatty cosmetics. £100.
Early 90's and pre E Bay they were just old bikes that nobody wanted.
By the way the first one came with a brand new genuine Suzuki seat still in its wrapping included in the deal -what would that be worth today ?
