  1. I posted on riquimbilly and figured I would share with you also

    > I am building a Lotus 7 type sports-car from scratch and grabbing at anything to keep from addressing the wiring mess Therefor I resurrected my Monarch bike with fresh cables and a change from 5-1/2 to 6-1/2 hp. Harbor Freight Tool Chinese engine. It drives through a bike hub Sturmey-Archer 3-speed tranny as a jackshaft. It has a Lambretta scooter carb and straight pipe formerly part of a trampoline. There is a Hodaka Ace 90 chrome fuel tank on it. The seat is 2" wide from an exercise machine. It is pretty rough riding with a rigid fork and no seat springs. Today I decided to use a spring fork I designed some time ago. It is a Schwinn blade fork backward with links pivoting to a 2nd fork on which a couple large valve springs cushion it's upward travel through a 1/4" thick 2-hole plate fastened to the rear and allowing the movement in the front hole. I used 4 shoulder bolts for pivots. It has gobs of power and quite restful to cruise on and tops out about 50 mph. Best of all, it starts well and idles nicely when the tranny free-wheels on coast. If it crators, I can psh it in freewheel without removing a belt. Final drive is #41 chain.

    Post a pic of that new fork and the Lotus Super Seven. A 1000 lbs super seven moves along pretty good with a Miata engine.

    I actually enjoy rewiring from scratch. Take lots of time planning and making scale wiring diagrams and find an accessible place to work.

    I see you have a Saab Sonett, here's photos of how I made a wooden box to contain most of the electrical components for a Sonett.

    That's really impressive to build a Super 7 the way you did. I like it a lot.

    Yeah, It's a 1974 with rusted out floorboards, broken front clip ears, master clutch cylinder problems, and seized calipers, I swapped a 1983 Honda Magna 1100 with worn timing chain tensioners for it and found it was seized after sitting 3 yrs. Soaked the bores with Marvel Mystery Oil and bumped the starter weekly for 6 wks, and it finally came loos with a stuck valve, which I tapped free with a mallet. Ran fine and drov e it synchronizing the gears and not having brakes, but managed around the block once. Has sat now another 3 yrs. Who knows? I wonder what the "engineers" were smoking when they put the fuel tank against the seat and the battery behind that for a detonator? They deserve to be out of business.
