Insane Vespa but my days of insanity are over, would not get the approval of the Honourable Minister for Finance and Recreation. In the 70's there used to be a Beetle with a mid engine Porsche engine in Vic and about 15 years ago there used to be a Kombi south of Bris, number plate read VWRX, went like the showers.
When I was 16 a mate and I built a mini bike frame around a 350 Jawa engine that another mate had semi totalled. Very bad welding very bad geometry, Harley sprung seat, hard tail, FJ column shift welded to what was left of the spline. I was the scourge of the Tullamarine freeway which was yet to be opened. It used to get serious speed wobbles at about 50 mph which you had to carefully ride through, top speed was unknown. Used to be chased by the road works crew in Land Rovers, they eventually gave up on me and just used to wave.
Did a few Frankensteins in my youth Jag 3.8 into a 32 Plymouth roadster, full house 179 into an FC a mate put a 318 into another FC. Don't expect to be doing any more unless son in laws start a worthwhile project. How about you doing a souped up Vespa apparently in the 60's a few Mods used to blow away a few of the Rockers on their Triumphs. It'll give you something to dream about.
Regards Martin.
