I also tightened the chain (yet again... another cotter pin, only like another 200km's since the last one!!! yep, gunna invest in one of those "R" clips

ANYWAY.... going from the "scale" on the adjusting bolts or whatever you wunna reference: How far back can I take the rear tyre before i MUST buy a new chain/sprocket set?
Cuz atm, I feel like I'm riding a dragster around!! Okay, not that bad, but damn I got a longer wheelbase now (owner before me had a 190 rear tyre, so he cut the chain guard to fit it, and this is the first time that the tyre is noticable PAST that cut!)
any reccommendations?
