Re: 93 900rr speedo healer help
Dude, if it's a '93 then you have the speedo reading off the front wheel. It doesn't matter what sprockets you're running. What matters is the rolling radius of your front end which should be 17".
Be interested to know what speedo healer you've got for that - I was looking for one of those a little while back, I forget why, but couldn't find one? Any details much appreciated..?
Either way, for callibrating whatever it is you have, if you have or can borrow a gps, or have a friend with a bike and working speedo. You could use the speed reading off the gps/otherbike to get a ballpark figure. Doing this with a gps is straightforward. For the other bike solution get out on a nice clear road, agree a sampe/target speed with your friend, wait for a signal that he/she's at that speed then ride alongside for a couple of seconds while you check your clocks. You could also do this by temporarily fitting a cheap magnetic sensor driven motocross/bicycle speedo, tell it the front wheel's rolling rad and callibrate your clocks by the readings you get off that.
