Hope I haven’t missed a post, but through searching all I could find are digital inductive tachs being installed. Recently saw a picture from a TAT page on FB with an XT225 with factory looking speedometer AND tachometer(believe it’s from a DT125/175) but the guy posting didn’t get any information or the riders name. I’m just wondering how difficult the install would be to have a gear driven, factory looking tach.

If you did find an analog tachometer driven through a cable. Where would you tap into the engine for the cable? And how would this be calibrated? I think an electronic tachometer with an analog dial would be much easier to locate and install. You can derive a signal from the primary of your ignition coil. I'd guess the pulses per second would be a factor of 2 and a time base conversion to get engine RPM. That would all be in the tachometer's internals. Just a thought. Good luck!

Right, I understand all that and that is my question. DTs have a hole right near the oil pump on the front of the engine where the mech drive for the tach comes off. I was hoping to find this person as a member here to fill in the blanks. I’d post the photo, but I’m not sure how to from my phone.

On the XT225, I'm not aware of any holes (or gearing) in the engine case for a tachometer.

This is the picture but it doesn't really answer any questions. Maybe someone will recognize the bike🤷🏻‍♂️

Actually the picture answered everything.I was going to tell you that the XT350 has a mechanical tach and to look there for possibilities as the front wheel is easily put on the 225 because it is the same except for a larger brake rotor.The minute I saw the picture it is clear that is a 350.I would still advise you to pursue the possibility of adapting a tachometer from a 350.

So I was confusing the tach cable with the speedometer cable. The wheel isn't the problem it's the engine and to be honest I've never missed having a tachometer on this bike.The only purpose I can imagine is knowing you are in sixth and not trying to shift into a seventh gear that doesn't exist.I do know people have put on the digital tachs and the only complaint is slightly slow response time.

Those little tach/hour meters are cheap but I've heard about response time issues for years. They seem somewhat crappy. At one time I was considering this.

The size seems good for our bikes. I like all the options and a stepper motor ought to give better response (no guarantee). But not waterproof is a downside and will require some sealing.

Unfortunately, I've never pursued it any further.

I was playing with the options for a different Speedhut 2 5/8" tach and came up with this today:


Not bad!

Car related tach's generally aren't set up to work with a single cylinder engine.
