adding a tachometer

 I am wondering if anyone has added a tachometer to a 1997 Yamaha
Virago 535. If not how hard is it to add one anyways. I've heard
positive and negative sides of the coil??

There are plenty of aftermarket electronic tachs you can fit, usually
sold for racers or custom bikes. Yes, very easy to fit. They look pretty
crap, mind.

Oh, and you might have illumination in it which would have to be plumbed
into the lighting circuit.

You can normally run a tach off the negative primary
lead from an ignition coil.

The trick is figuring out how many revolutions per spark
on your bike and buying a tach that's set up accordingly.
I like tachs designed for HDs because they're dirt cheap
and there are a zillion of them out there.

My older BMW airhead generates one spark per engine
revolution, so I run a cheapo eBay tach designed for
an HD "dual fire" ignition. If the coil were generating one
spark for every two revolutions, I'd go for a tach designed
for the HD "single fire" system.

If you wanted to wuss out, you could go for a slightly
more expensive tach that's designed specifically for
your bike, then follow the manufacturers instructions to
install it. Takes all the fun out of it though.

 
i was going to go for a 39.95 tach from jc whitney. its chrome and
goes up to 12k.

If I'm reading it right, that's a mechanical rather than an
electronic tach. For a '97, I'm pretty sure you want electronic.
That looks like the wrong stuff.

Also, does the engine really go to 12k ? Kind of a waste if
the tach goes to 12k and the engine's toast at 8 or 9k.
Better to buy one that matches the engine's top RPM
plus a very tiny bit extra.
