So a couple of months ago i put a 16 tooth front sprocket on my FZ1s so i took a satnav on the tank pad to check out the speed correction.
I found the bike to be over reading as expected , the speedo read 44 to satnav 40 ,speedo 55 to satnav 50 and so on, so there is a 10% over read, easy to calculate when riding.
I got the speedo to read 142 and the satnav recorded 128 max speed of trip.(on a closed airfield of course) :\
On my Hilux pickup the sat nav reads slightly less than the speedo for cross reference,50 on the speedo and 48 on the sat nav so that 4% is my safety factor on riding at speed limits.
SO as written about the sprocket change making a 5.4% over read and the inbuilt 5% over read on the bike speedo i know where i am.
And as for the 16 tooth mod well, i takes away the need to change down to over take ( in most cases anyway) and makes for a smoother ride.
I have recorder 130 miles on the milo and the fuel is flashing ,so have to check what is left in the tank as i want 150 miles to the tank or if not then the 17tooth is going back on.
Four of us are riding to Mugello end of May, going through Switzerland , my mates gsxr 750 needs to stop at 150 miles so should be ok.

don't forget you your m.p.g. should show a 5.5% increase if you're still getting the same m.p.g.

I am expecting it to do 5.5% less mpg, but the throttle control is all to shit,,i cannot turn it steady, it wants me to turn it fast all the way :evil

and when your tyres wear out it will reduce by 4%
