does it not go to the coil - ?

[superang]

well i hooked It up TO THE ORANGE WIRE AND I STILL GOT NO READING AT ALL... I CHECKED ALL THE WIRES AND I TRYED CHANGING A FEW THINGS BUT I STILL GOT NOTHING.... I DONT KNOW WHAT THE PROBLEM IS?

what kind of tach is this? tachs are cylinder specific, if it's for a car you probably won't get it to work.

[BLUE STREAK]

could it be you don't have any power at your ignition source I would wire it in to the head lights and just run with the lights on all the time.

 

I am assuming this is a motorcycle tack because if it is an automotive one it wont rev high enuf.

[DIRTMAN350]

Make sure that you have it set on the right cylinder setting. It may be possible that it won't read rpm's due to not haveing a true 12 volts. just my opinion.

[superang]

what kind of tach would i be looking for to make it work?

and where would i find one?

[BLUE STREAK]

I did a 1 hour search on Google and I could not find any thing for 2-stroke's.

 

the only things for us mixed gas guys is for Marine boat stuff

 

But if you do find out make shure to post up with details.

[macgillivary]

i thought about a tach a while ago but it seems the only one that works is a really espensive computerized shit

 

what woudl happen if you stole one from an rz or something? that might work but you would need a battery probably

[rzcolobanshee]

No need for a battery because the rz tach is mechanical. You would either need the top half of an rz case or you could modify the banshee case to put the tach drive gears in.

[PUSH THE THROTTLE]

Get yourself a tiny tach like $50 from Dennis Kirk or elsewhere. all you do is mount it and wrap the tach wire around a spark plug wire. I used to run one with no problems. Make sure you get the twin cylinder 2 stroke version.

[rrr]

I would check scooter tacks. They are made for two stroke but single cylinder. Not sure if it will work but it's worth checking.They are cheap and some of them rev up to 15 000 rpm.
