"Has been modified with the cam and pipes. It is a real performer. It has not been started in 2 years"This is based upon the ebay principles of a 'full and acurate description' so as to avoid any unpleasantness at a later date.
The first part tells a little of the state of the camshaft, i.e. it is no longer to Honda specs - it's knackered.
Going on to the pipes, these likewise are in a state that is likley to render the vehicle unsuitable as a form of transport, i.e. rusted out and bashed to hell.
It's a real performer - trickey this part, I can only conclude this is an affirmation that the machine realy exists unlike those purchased from some less reputable traders based in the african sub continent. The word 'performer' indicates that not all moving parts are totaly siezed, perhaps you can still turn the bars a little with aid of some stout chums.
'Has not been started in 2 years' - the bramble growing through the back wheel had fruit last summer so must now be a minimum of 2 years old.
As you probably noted this is quite a specialised language which has been nurtured and devloped by estate agents over many decades. I believe you can do a diploma course in 'talking bolox' these days.
Having had a Grammar School Education I learned one thing which helps - et caviat emptor (which I probably spelt wrong) which for those of you who who were less fortunate educationally means 'buyer beware'
