It was a 1979 GS750. The bike was working great before I disassembled it.

I re-wired everything using my own custom wiring harness. I didn't wire up any lights except the Enging Oil pressure, Gear indicators, and backlights for the dash. The Spedo is not connected right now. I would run the spedo cable off the rear axle and calibrate the gear ratio so I'd have a correct MPH reading. Normally, this is run off the GS750's front wheel. I'm not going to bother with the Spedo, but I will install the TACH cable. I'm just looking for a longer one. The original TACH cable on the GS750 is only 30 inches or so and I need about 90 inches.

I would design/build something completely different for driving on the roads -- this is intended strictly for racing.

I'm assuming the bike you used had 34K on it? What year was it? Being you have all the wiring for a taillight and turnsignals and a headlight, why don't you buy a set of 12" or 13" lawnmower or other wheel that would work and mount DOT legal tires on them and get it regestered with a hombuilt registration, you would need at least a lap seatbelt if you did. A Carlisal Turf saver lawn mower tire might be Dot legal. The dash is cool with the shift indicator but your Speedometer is not accurate, that will need to be recalibrated or the speedo drive gear in the trans like on a car ( older ) is and you just change the speedo drive gear and it ajust's the speedometer, right now it's going to read way faster than actual unless, you get a larger rear sprocket to match the original rear tire speed ( when on the bike ), and match the final drive ratio of the original bike. That may be the only way to go because they may not make speedo drive gears for your application, you could also just have someone drive a car w/ accurate speedo next to you, and then get the cart going so the speedo reads like 55 and then stop and ask them what the reading on there speedo was and use that number to go by and you will be able to add or subtract depending on the Mph the car went and the reading of your speedometer.
