If the bike is using 12v as the power supply (battery) why not add a power resistor to drop the power to the tach? (will have to work out the correct ohm rating for 9.6v though)
"KARTECH ENGINE TACHOMETER"
: 2 Cycle or 4 Cycle
: Maximum RPM
: Running Time
: Dual RPM

same tach i use
but i got mine second hand, so im a bit sketchy on all its features and how to use them.
ive got it set up on my bike, so it reads the revs but im not sure about the rest of it.
can you pm me with some detailed instructions please???
