Need a digital guage for a single.

[50gary]

Help!  I built a DT250 single cylinder converting it to a nifty little street bike.  Now I need a nifty digital gauge that's compatible with a 2 stroke, single cylinder.  I bought and installed a KOSO knock off and the tach is not working accurately.  Any help is greatly appreciated.

50gary,

i have bought 5 of these for single cylinder two strokes and i find them brilliant, you can set the wheel size for speed, the number of cylinders for revs. etc. it even has a battery voltage meter. i have the tacho connected to the feed signal from the cdi box, which if you dont have it would need to come from the coil feed which i have not tried.
the chinese translated instructions are pretty straightforward to "interpret" but if you have any problem let me know.
