Speedo and Tach 650RJ

I talked to the PO and got the speedo and tach but he didn't have the other indicator lights. I do have the plastic housing for them though. Since I have a 750 motor, how do I get them to work? Also the rubber seals on the gauge housing were really bad, literally crumbled when I touched it. There anyway I can seal them without buying replacements?

 

the tach is electronic correct? black (ground) and blue (hot) wires are for light bulb
brown and red (orange) are for tach connection brown is hot brown wire from key, red (orange goes to orange wire on coil

750 motor with 650 harness just to help me?

 

@XJ550H The PO put a 750 motor in but I believe it still has the 650 harness and everything else. Also the tach is mechanical. It has a slot in the back for a cable. Forgot to take a photo of that.

 

the tach will not work for you 750 has electronic tach

 

Ok thanks, I wasn't sure if I could make it work. I saw some stuff on converting them to electronic somehow. Any recommendations on what kind of tach I should get or just leave it off?

 

All you should need is a stock electronic tach to install in the housing and of course the wiring harness to hook it up. I may be wrong here but that's my initial thought

 

The only stock electronic tach that will fit/look right is from a "late" (red paint) XJ650RJC Canadian model (those had the YICS engines, so no mechanical tacho) or a Euroland XJ650 (I believe 1982-later) as those also had the YICS engines. Also, the XJ900N ("naked") 1985-86 model, but those only were available in the Oceania market (Australia, New Zealand, etc.).

 

I'm in the process of finishing up my build with one of the eBay/Amazon gauges. Check my build and see if you like it. I just need to configure the speedo sensor after I get her running.

It's a different look than stock if you're into that.

 

@chacal thanks for the info, not sure if I need a tach right at the moment. I have a few other things I want to do like turn signals and ss brake lines.

@Taylo105 I do love your build, but yours is a bit more fitting for that type of gauge. I love the stock look and think I might even put the OG handlebars back on. I also don't have the oil lights and stuff so if I could find a gauge set that has that built in then I'd be happy with that.
