The barrels have to be replated. Long gone are the days of cast iron liners and reboring in high-performance 2-strokes.
Yes, £100 a barrel to replate doesn't sound cheap, but bear in mind that MC16 barrels will be at least 18 years old now, that wear only works out at about £11 a year! Use high quality synthetic 2-stroke oil, and there's no reason why the barrels won't go another 20 years! (Unless your name's Luke! )
Like you say, you could invest in another motor, but who's to say it will be any better than what you already have? Once replated, the barrels are effectively as good as new.
Go to Langcourt direct for cylinder replating. It's the service 95% of the trade use anyway, so cut out the middle-man!
