Finger AND Screwdriver adjustable extended Fuel Screws

Frustrated with trying to find an "almost 90 degree"  screwdriver to fine adjust your fuel screws for best idle and cruise?
Use Factory Pro's new "finger adjustable" fuel screws to adjust fuel screws for best throttle response. Traveling to high altitude? It's easy to lean out the lowend temporarily.

Make your life easier!

Installation:
Remove old short stock fuel screws, old o-rings, old washers and old spring. The o-ring might be stuck in the carb, so, take a light and make sure it's really out if it didn't come out with the screw (or you can't find it after you took out the screw)
Use a small bent wire to pull it out if it doesn't drop out. Keep the old parts for "spares".

Extended screw assembly comes with:
4 Long Boy fuel screws 
 4 new o-rings
4 new washers
4 new springs

1.7 RaceKit

Slightly more complex to install than our "drop-in" kit.  No slide drilling.
Use with stock or aftermarket exhaust.

First choice in carb kits for this bike.

Makes best power, overall. Period. Was used by every Pro AMA and EVERY WERA roadracer at the GNF.
Absolutely the best performing kit for on and off track use. When properly tuned, this kit produces the best low-end and midrange possible - and adds 2-3hp to the top-end power.
This is the ONLY kit to use for best power.
Imagine! You can still buy the trickest parts that were ever used!!!


CRB-Y71-1.1-TI   $159.95

Ti Pro Kit carb kit

Drop-in Kit. No slide drilling.
Titanium needles. The toughest material used in a carburetor. These needles will still be around in the millennium after next.
The kit, when properly tuned, adds more low-end / midrange and if the proper main jet is selected, more top-end power. Easy to install and tune - no slide drilling!


CRB-Y71-1.0   $139.95

2.


Drop-in Kit. No slide drilling.
Our own Celmat30 needle material. The most durable material, aside from Ti, used in a carburetor. 
The kit, when properly tuned, adds more low-end / midrange and if the proper main jet is selected, more top-end power. Easy to install and tune.

RTR-YAM-1    $89.95

Ignition Advance Kit

This IS the kit that every top WERA / AMA racer used.

Adds more lowend, midrange and topend - and pulls better off corners - better trackday and in-town bike.

Let me say this:
There is no Ignition Advancer kit specifically for this bike.


ALTHOUGH - this RTR-YAM-1 kit contains the magic offset flywheel key that will advance the ignition timing 5 degrees.
The kit DOES NOT contain the flywheel puller that is required to remove the stock alternator flywheel A Yamaha dealership would have the 3 arm puller. And probably most shops will have a 3 bolt puller.

Make shifting MUCH quicker and virtually eliminate missed shifts. This is exactly the same kit that Yamaha Racing used. Huge shift action improvement. 

Trans Detent Arm Kit

The kit requires the removal of a 27mm clutch nut - so, you'll need a:
Deep 27mm socket and an Air or electric impact wrench
If you insist on not having an impact wrench, you'll need and appreciate....... A friend to hold the rear brake on while you loosen the 27mm nut while the bike is in 3rd (ish) gear.....

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.
