Yamaha 750cc Swapped Isetta Seems as Good a Way to Die as Anything

isetta with yamaha swap We love to upgrade our cars for more power. How many of us have sextupled the original power figure of our cars? Such is the case with is 1957 BMW Isetta that’s had a 750cc Yamaha twin swapped in. Quoth the seller:

The guy I got it from thought it needed the protection of a rollcage because the stock engine was only 13 horsepower and would do 50 mph. so with about 80 hp. maybe it was a good idea.

See? Perfectly safe. The seller says this project is close to completion, but based the photos it appears to have the motor dropped in place and the body, paint and interior sorted. Thankfully, the leftover parts from both the Isetta and Yamaha appear to be in well sorted and bagged, rather than just piled in the back seat/truck/nearest bucket. Induction/exhaust? Engine cooling? Shifter? Pedals? Linking the chain drive up? These are but minor details.

Still, the idea of that big V-twin thrumming beneath your seat while you obliterate golf cart tires at every stop light is an attractive one. Not sure it’s the current bid’s $5100 worth of attractive, but attractive nonetheless.
