[Gearbox]

I wouldnt take ownership of the bike until after the belts have been fitted , nine year old belts that have stayed stationary for long periods are ripe to fail.

Otherwise if it looks well looked-after then go with your/your friends gut feeling especially how the guy talks about his bike.

These bikes tend to be well loved and the problems they have can generally afflict any make/model in some way so dont be put off by all the forum doom-sayers...
