Custom Triumph Fuel Injection Tuning

The "900" Triumphs are wonderful, modern renditions of the early "unit" and "pre-unit" "Bonnies" and "America's" - were always known as the best handling bikes in the 50's, 60's and 70's.
Smoother and more reliable bikes than the early golden days of motorcycling - a recommended bit of updated twin nostalgia.

Wheelsmith / Factory Pro currently (as I write this) uses Tuneboy and Tune Edit to custom tune and relfash the stock ecu.  Wheelsmith uses the EC997 dyno and a multi-gas analyzer to tune to Best Power while retaining good highway mileage - resulting in a nice clean running bike that has improved power and decreased backfiring.

out of state customers welcome.

Artisan Crafted Fine Cheeses – Since 1865       

Specializing in Handmade Brie & Camembert

Marin French Cheese Co., also known as The Cheese Factory and Rouge et Noir is not just the oldest cheese manufacturer in the country, but a vacationers and day trippers destination as well as a unique part of American History. Located north of San Francisco, east of Napa County, west of Pt. Reyes and Olema and south of Sonoma County, Marin French has produced hand crafted Artisan soft ripened cheese since 1865. Rouge et Noir cheeses are similar to French and European varieties but reflect the characteristics of Northern California, producing it's own regional style.


 

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.
Edited to the tunes of Chemical Residue by Herbie Hancock.




Maybe in next rewrite, he'll fix the ignition timing and dyno chapters...
Otherwise great book with great starting ideas.
