??Tach??Tech Question

[IQmodster]

What tach(s) will work correctly with on an IQR. I have a big block 800 installed. Can I run one off an XC or what? I thought they differed in pulses?

I don't see how it would matter. I have a tach off of a IQr you can have for $40.

Why it matters

I agree with you, but some people are telling me some tachs read different pulses. Anyone else throw in their thoughs?

polaris fugi engines run 2 pulse set-up and the liberty uses a 6 pulse set-up

I just got done putting a 800ves in an iqr. The stock iqr tach works fine on it. If not, make sure the voltage reg works. In my case, the kid had run the sled with no headlights or handwarmers and had burnt up the vr so the tach would not work above about 3000 rpm. Changed out the vr, and now it works fine as do the lights that are now wired in it. And yes, it is a 6 pulse tach.

Thanks

Thanks. I am running hand warmers ect., just no head light. This shouldn't affect the VR, should it? I have another VR I will try. Thanks again.

Running with no headlights will generally burn out the vr as there is no other draw on the system and they can not handle that. What guys will do is add another set of handwarmers wrapped around the steeering post that are always on to put a drain on the system if they choose to not run lights. This will keep the vr alive so the tach and guages will will work, and a helmet light for night riding. Without anything, you will burn out another vr.
