F-Pro Shift Spring
Replace soft stock shift spring for "better than new" shifting.

 A MUST DO for dirt track.
Improves manual and quickshifter shifting.

Brightens up shifting and virtually eliminates missed shifts and damage caused by missed shifts.

The 650 has a pretty good  detent arm  but you can make some  additional improvement with a
Hybrid Ceramic Detent Arm.
Installs under the clutch basket. Take 1-2 hours and a 1/2" impact wrench. Clutch cover gasket not supplied.



 Use arm and spring for best results - but if you are on a budget and only buying one part, buy the spring.

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.
