As I recall -

We ran over 100 AMA and WERA bikes, we gained between 2% to 3% power.

The least I saw was 1% (JR's super loose built race engine) and the most I ever saw was 4% (on a super tight street  built engine).

The other 98 bikes picked up 2% to 3% power - with most 2% and  2.5%

Lasts 2 and up to 3 oil changes (tapering off in effect).

Helps highway mileage.


Absolutely NO carb parts sold in California.

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.
