| |  Installing A Speedometer
Hey guys,
Wondering if it is possible to install a speedometer into a pit bike.
I have a PitPro 140 XR by the way.
All I want is something shows the speed and maybe the RPM.
Im doubting it is possible though.
Anyone got answers?
Thanks, Mitch.

so your saying that there wouldnt be speedometers out there with the wheel diameters I have?
couldnt you adjust that if it was a computer one with like a LCD screen?

pretty much, some use worm gears and take the speed from the gearbox.. RPM will be taken from the coil.. Cycling computer, works sweet...
bout half way down the first page...

supposably the charge from the motor interacts with pushy speedos and makes it say your going heaps faster than you actually are
