1983 Suzuki GS850 Cafe Racer Project

I like it too, the best use of an L tank and the seat looks very nice and looks comfortable too. The L forks won't slow anything down if you used the same triple clamps which it looks like you did. The wrinkle finish is a nice touch, is it paint or powdercoat? One thing to think about with shock length, the driveshaft is happiest at a certain angle, hard to tell from here, but it looks like the swingarm is already angled down further that it was originally?

That looks about like stock rear end geometry for an 850. Being on the center stand with no exhaust, it looks a little unusual.

...I suggest dumping those L forks because they slow down flick-ability.

The difference, if any at all, is so tiny, 95% of riders will never notice the difference, especially on an 850 or 1100 shaft drive. Those bikes are FAR from "flickable", in any case...

A little teaser.

Can anyone help me out?

I am looking for a positive connection for the RPM to complete the connection of my digital gauge. Does anyone know?

Depends on the unit you have, but I have my Trail Tech Vapor tach lead connected to the '-' side of one of the coils. You can also try the '+' side, it seems to give a weaker, but less noisy signal.

Where did you get your seat from, and how did you mount it?

Really liking your build, and I'm impressed with the quality of your work!

On my gs550, I added a chi-bay electronic tach/speedo unit.


To get the tach to work, I took the (-) side of the coil and tapped to the tach signal wire on the gauge. where the wire for the (-) coil and tach signal wire connected, I tee'd a 10k ohm 1/4 resistor to a 12v wire and everything started working.

I have a ChiBay unit, and can't get it to work in any way shape or form. I can get it to somewhat work by wrapping the signal wire around one of the spark plug wires.

Thanks. I got the seat off of EBay. I have not mounted it yet, however I have two options, two bolts directly through the electronics pan and into the seat where the brackets bolt to the seat pan, or weld nuts onto the seat brackets and go trough the side of the sub-frame to the brackets.

I'll let you know how I did after I do it.

Can you post some pics or a diagram? This seems to be very interesting, thanks.

schematic is half way down the page on the above link. only difference was i connected to ONLY one of my coils.

Soon Steve, soon.

Thanks for the link frankenwabbit

Found a good signal and here it is:

oh...btw...if you don't have a fuel sender in your gas tank and want that fuel level gauge to stop blinking...just connect the fuel sensor wire on the gauge to ground....if that doesn't work...you connect the fuel sensor wire to a resistor (forgot the value) and then to ground. Something like that.

This bike is looking great! Can't wait to see the result!
