Sprocket change for an old foccer

[ade the blade]

don`t want to be a damp sqiub about this, but i`ve always been a bit wary of changing sprockets (especially a smaller front sprocket ) as i have seen some very badly chewed up swing arms over time. happens pretty quickly too. just be careful and check regularly for any abnormally fast wear. Mr Yamaha put those sprockets on for a reason as does all other manufacturers. just my ramblings. ...feel free to tell me to rotate if you wish. cheers Ade
