Honda vfr500 - VF500f, 84-86

A VF500f is like a refined VFR750. Smoother, better handling and a joy to ride. 

It's relatively mild state of tune just begs for a bit of "tuning". One of the smoothest bikes around when at full tilt.

The Carb Recal Kit perks up the low-end and midrange power and improves response for quicker warmup and more response. Better all around. Fills in the holes in the powerband and makes the miniceptor VFR even more fun!

This Factory Pro Carb Recal Kit, when properly tuned, adds more low-end / midrange and if the proper main jet is selected, more top-end power. Works with stock and aftermarket exhaust systems as there is a selection of main jets supplied, along with suggested settings for initial installation.
Easy to install and tune - no slide drilling!

The extension of the laboratory for engines of the Swiss Federal Institute of Technology was completed in about 1935. Its architect was Rudolf Otto Salvisberg (1882-1940). He had a successful career in Berlin but returned to Switzerland after the advent of the Nazis. His architectural style was somewhat similar to that of Erich Mendelsohn. The staircase of the laboratory is in normal use but well preserved.
