Forgot to let you lads know, I uploaded a file on the difference changing sprockets or tyres will make to the speed of the Fazer 1000.
It is an XLSX file which allows you to enter the Sprocket sizes or tyre sizes and and see the difference it makes to the speed in each gear.I found it I think on the FZ1 site on the net a good while ago and modified it to make it easier to follow, hope the original owner does not mind.
Forgot all about it until some one asked a question about sprocket changes on Facebook.It is under useful stuff in the downloads section
