Spark plugs

Denso Spark Plugs

U24FER-9 Original equipment
Standard replacement plug from the largest supplier of electronic components to the MC industry in the world.

~$3.00

U24FE-ZU9 Upgrade spark plug
Premium, Platinum, U Groove spark plug.
It is recommended to start a tuning session with new spark plugs.

~$7.00

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 with 18mm spark plug wrench required
24 = Heat range. (Hint - it is ~3x NGK #. I.E. an "8" heat range in NGK)

P = Projected tip type plug
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..)

Northern California's most unforgettable flying experience. No experience required. Open weekends!

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.

Honda VTR250 89-90
Factory Pro Series "H15"

The VTR250 is one of the funnest bikes to ride - an excellent first bike and and excellent budget racer. It's relatively mild state of tune just begs for a bit of "tweaking". One of the smoothest bikes around when at full tilt.

The Carb Recal Kit perks up the low-end and midrange power and improves response for quicker warm-up and more response.

Jerry Einstandig really likes his restored VTR with its modified airbox.
