Been thinking about a new chain and sprockets this spring. I'd like to go -1 front, +2 rear, or even stock rear. Also thinking of a 520 conversion at the same time. Couple guys on Gixxer.com are warning me that my old 92 750 will chew up a 520 in weeks. Any input here? I tend to trust the locals, more than the blowhards at Gixxer.com.
