Spark Plugs,
Denso

U27ETR - Standard replacement plug from the largest supplier of electronic components to the MC industry in the world. ~$3.00
U34es-nzu - Premium, Platinum, U Groove spark plug.
It is recommended to start a tuning session with new spark plugs.
~$10.00
Denso (ND, Nippon Denso) is the largest OEM supplier for autos and motorcycles of electrical components in the world. Sometimes, people forget that Denso makes pretty darn good spark plugs, too! Wide heat range properties discourage plug fouling at low speed AND overheating at high speed.
We have been using Denso spark plugs in our AMA Supersport bikes since Denso was Nippon Denso and ND. We have found that some standard, <$10, off the shelf, Denso spark plugs work as well as $125 special spark plugs - on a professional roadrace level!
Codes:
X = 12mm thread w/ 18mm hex
27 = Heat range. (Hint - it is ~3x NGK #. I.E. an "9" heat range in NGK)
E = 3/4" reach
P = Projected tip type plug or
T = Dual ground electrodes
R = Resister type internal construction
Z = Thin platinum center electrode w/ tapered ground (side) electrode
U = "U Groove" side electrode for better spark and finally..
9 = is "pregapped" at .9mm (You should check any "pregapped" plug before you install it..)

Tools

 
TL-float height gauge
$59.95

The only way to accurately measure float heights. Works on nearly every carburetor.

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.
