[2fst4u]

hey mate ive done it before theres a thread on it.

u get 3 wires, green, red and black.

green: goes to ur coil
red: to battery +
black: to battery - or ground.

i found that they dont like single cylinder operation very much.
tacho's a better way to go.

 

[2fst4u]

got any pics or a layout of the wires

any 1 got a small tacho hooked up to there bike if u do how and some pics would be great

mate ive done that too.
same wiring as the shift light.

u can get other tacho's that use inductive pickup which you wrap around ur spark lead aka tiny tach.

do you seriously have time to look at that thing when your racing? you dont see tachos and shift lights on motocross bikes do ya why bother putting one on a mini

wouldnt a pitty engine rev well past 9000rpm tho? rendering that tacho useless?

the bike is going to be registered and i use it to find out what rpm im doing at what speed. im always curious to see what engines rev at too.
im preety much not gunna rev the thing past 8 thou rpm if i dont have to either, cause power will drop off by then.
