Ok, I just got my oq R6, it had been sitting awhile so the chain is all rusted and I tried to clean it but its alot of rust, I mean alot. So I have been asking around talking and stuff and now I am really lost. I was told about sprocket and chain conversions. I am talk about the 530, 525 and 520. I have heard multiple ups and downs of all of them. I was told the 520 would be like a dirt bike comparision and that it was more for racing on a track and would wear out quickly. So I dont want that but then I hear that would would help alot. Then my boy owns a shop and he is tellin me that the 530 or maybe the 525 would be fine. I plan on going down 1 tooth in front and maybe up 1 or 2 in the rear. I just dont know what conversion to do PLEASE help. THanks
