Just a quick question. I currently have a 190/50 tyre on ther rear but am changing back to stock now that it finally needs changing. Whilst the wheel is out i am putting a 43 tooth rear sprocket on.
I have seen calculations on here about how much it will put the speedo out, but to be honest maths aren't my strong point.
In simple (idiot) terms how far will the speed be out, and is it worth investing in a speedo healer, or is it such a small difference it isn't worth bothering about.
