Hi all, i have picked up an 88/89 gpz 500s , have not ridden for 20 years, so until i pass test am working on bike to get to good standard, done plugs filters oil, now want to put new brake shoes in back and change chain and front and rear sprockets at same time, i heard reducing the teeth on front sprocket and increasing teeth on rear will increase acceleration, donĀ“t need high top speed, just be able to leave sports cars at lights, any advice will be appreciated, Peter
