CV Carb Tuning

  

Factory Pro method for tuning CV carbs - As in most stock motorcycle carburetors.
This is the motorcycle world's primary source for proper CV carb tuning procedures. AMA Proven Tuning for the "average" guy, too!
All written by Marc Salvisberg using 35+ years worth of tuning experience.

   ECU Adjuster tool tuning procedure - No pc required - Do your customers a favor!

Honda RS250 carb tuning

     Tuning RS carbs and ignition on the Factory Pro low inertia EC997 with 4 Gas - you need the 4 Gas EGA to properly tune for best power and part throttle power. You may never make as much power as the top AMA bikes - but you CAN avoid throwing away the power the engine makes-
Yamaha TZ250 carb tuning     Tuning TZ carbs and ignition timing on the Factory Pro low inertia EC997 4 Gas EGA dyno - the overwhelming choice of AMA Pro racers. It's the only dyno that tunes to realistic track settings. Really..... We mean it - Ask Rich, Robert and Simon!

    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.
