make / manufacturer: Yamaha / VW
model name / number: SECA 750
I started building this in 1984 from plans from Mechanics Illustrated. It is street legal. I have a special title identified as a reconstructed vehicle. It's licensed as a motorcycle. I had to have a DMV official inspect it and he stamped a serial number on the frame. I started with a wrecked but running Yamaha SECA 750 with a drive shaft and a pretty cool instrument cluster, I think it was a 1982. Then I bought a NEW remanufactured VW Bug front suspension with shock towers, shocks and hydraulic brakes included. Then I build a custom welded frame to tie the 2 units together out of new rectangular steel. There's a joy stick with the motorcycle grip with electric starter button and clutch lever to shift the transmission connected with a pivoting rod assembly that I custom made as you can see in one of the pictures. I extended the bikes wiring to the bikes instrument cluster/dash board attached to the VW steering column. There's tubular square steel surrounding the upper half of the center bulkhead and channel bar steel encased in fiberglass around the T-Bar top and windshield frame and seat belts in case it ever rolled but it felt very stable when cornering so I probably didn't need it. The body was formed with bulkheads then covered with 1" urethane foam. The foam was then sanded to the final shape and covered with 2-3 layers of fiberglass. I occasionally drove it around for a few years and was concerned about the engine over heating so I put in a cylinder head temperature sensor under one of the spark plugs. The sensor gauge is visible in the pictures below the steering wheel, mounted to the steering column. Then I installed an oil cooler with a fan in front of it in case I was stuck in traffic and air ducts below the chassis to pull air in to the engine compartment to blow through the oil cooler. The rear facing top scoop and louvered side panels on the engine compartment hood pull the hot air out. If those louvered side panels look familiar they are from a Datsun 280Z. It has a Kerker header system. There are head lights in the front but they are not pictured. The turn signals are wired up to the VW steering column. Also it will need a small car battery. I made an emergency brake system with a lever on the floor and cable system to the bikes rear brake.
My first son was born in 1986 so this project got set aside for 24 years. Then I stated to work on it again, of course the carburetors needed to be cleaned out. I had a friend who used to be a bike mechanic remove and disassemble the carbs and clean them out. Then re-install them but it wouldn't stay running unless I sprayed starting fluid in the air intake so the carbs will need to be serviced again. Then in 2019 I realized the front left wheel was locked up when I tried to move it. I don't know if it's the bearing or something in the brake. I now realize I will never finish it so I need to find a good home for it with someone who will enjoy finishing it. I'm asking $2995 or best offer. It probably has $8000 in parts and materials and countless hours of careful labor. I have the title and current registration. Thank you, Tim
