I'll measure diameter of link pipe and pm it to you tomorrow as too dark in garage now!
It is in top condition, just needs a touch of autosol on it.
Basically it was on my mates sv in the showroom and when they delivered it too us they'd changed it back to the standard thinking we wouldn't notice i'm guessing that was because we're a couple of girls that know nothing about bikes!? Little did they realise I'm a trainee Bike Technician and picked up on it right away. We kicked up a fuss coz the price we paid included the ART can. so it never actually got round to going back on the bike (joys of running a pub!
)but has been safely stored in the box for the last year or two so it should be practically good as new (barring use by previous owner but it was obvious that he loved that bike)
