I only bought the bike a couple weeks back and I thought at the time " chains a bit slack, must tension that up a bit" never did do it, and reading your write up I can see now it's just how it should be. I'm starting to think the bike must have been owned by a foccer, before the feller I bought it off, all the signs are there, sensible mods and upgrades, exup in GWO, been well looked after and maintained.
