1989 3CV Streetfighter Project

Hey Fred. I'm terrible at wiring. Any and all details are appreciated.
Awesome build Fred.

The best advise that I have for wiring is to get one of these 4 page diagrams.

This one for your 86

They are much easier to read than the single page diagrams in the Haynes manual.

The bikes are loaded and ready for the Vintage Yamaha Rally.
I will be making a stop in Arkansas to Visit Craig Ovadia. An additional bike will be added to the trailer. I purchased this and Craig picked it up for me.
The little Honda has sentimental value. I had a 1986 Interceptor 500 as my very 1st street bike when I was 19. I bought it at the same dealership that Pat Conlon bought his 84 FJ1100 2 years earlier.

I have not had the chance to do much on the Streetfighter since September. It was a Great hit at the Vintage Yamaha Rally. Even in it's non-running state.

The high mount exhaust has not given the look that I had envisioned. I have decided to do a low, stubby exhaust instead. The photos are just a mock up using the current mufflers and a set of KO mufflers that will probably be used.

The low setup looks better by a lot...much neater.
I actually prefer the look of the low black silencers to the ko ones

Same here. Black one. Awesome job Fred.  The first thing I thought looking at the picture of the bike was the exhaust has to go. Scroll down and you already fixed it.

Add another vote, for the low black mufflers!

I like the black mufflers too .... BUT either choice would still really show off the single sided swing arm conversion in the future .....!

And the wire harness build has begun. Looks like the Really inexpensive all encompassing Speedometer/Tachometer unit will not work.

I have found a TFT style unit that I will attempt to install.

Hey Fred I really like the one at the bottom do you have a link

I have decided not to go the cheap/inexpensive route on the Streetfighter 1200 instrumentation. I am going with the High Quality Koso RX4 TFT Meter.
As my friend Roger likes to say, "If you buy quality parts, you only Cry Once."

Since the modern Multifunction Display will have gear selection indication. I figured it would be prudent to remove the Neutral switch and add a gear position switch.

Fred, does the indicator in the dash work off a discrete signal per gear - i.e. this pin grounded = 1st, next pin grounded = 2nd, etc?  Or does it go off different resistances per gear? 

I think Randy's setup is the first, while most factory bikes are the second.  I haven't thought all the way through how to get Randy's switch to act like the second way - seems you would have to run 5 volt or 12 volt power through it BUT the shift drum would be grounded to the engine cases? 

I bought the gear position setup from RPM when it came back in stock, but trying to figure out how to make it work with my electronics - - hopefully your setup is straight forward.  I'm thinking mine will require some type of analog to digital converter, or a bank of miniaturized relays and various resistors?

I will let you know when I get the bike powered up.

Some more progress and yet another instrument change... since I decided to go with a quality Guage package. I am finding that many others have the same idea and the Koso TFT Multifunction Meter's are very popular and are out of stock through most distributors.
Robert at RPM has come through and I have a Koso MS-01 on order. It is much more like the simple round design of the cheap Chinese version that I started with..

The wire harness is coming together nicely. I have the original wire harness plus a 2nd wire harness that I am hacking apart so that ALL of the wires stay the exact color code.
