"Long Boy"
 Finger and screwdriver adjustable extended Fuel Screw assembly

Frustrated with trying to find an "almost 90 degree"  screwdriver to fine adjust your fuel screw for best idle and cruise?
Use Factory Pro's new "finger adjustable" fuel screw to adjust fuel screw 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 screw, old o-ring, old washer and old spring. The o-ring might be stuck in the carb, so take a light and make sure it's really out  (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".

Screw assembly kit comes with:
 new extended screws
 new springs
 new washers
 new o-rings

Config 10 jet kit
For when you KEEP the airbox and run a stock or stock replacement air filter.

All of our carb kits come with a selection of jets to allow for perfect tuning and AND special needles that were designed to run with larger pilots.  They weren't designed with the goal of "getting away with only" jetting.

The "800" and "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 - The larger Thruxton's and T100 tune the same.

Best (only?) "drop-in" kit available. Nice even power improvement.

Not really fussy about main jet selection (other than the bike loses 1 hp on either side of the perfect, best main jet). Needle height is pretty cut and dried, with little fiddling required, from what we've seen and heard.

Nice kit and easy to install - a genuine pleasure to work on a bike that was easy to tune!

As usual, boosts power a bit at full throttle, improves throttle response and wheelie ability. Definitely pulls harder out of 2nd and 3rd gear corners. Gets rid of that pesky flat spot at low rpm, when properly setup.


CRB-TD14-3.1-TI   -  $109.95

Oh my, oh my!
 They call it "freak" when you remove the airbox??? Oh, well, "kids, these days!"

Config 30 jet kit
For when you remove the airbox and run individual K&N air filters.

Nice kit and easy to install - a genuine pleasure to work on a bike that was easy to tune!

As usual, removing the airbox boosts power at full throttle, and the jet kit improves throttle response and wheelie ability. Definitely pulls harder out of corners. Gets rid of that pesky flat spot at low rpm, when properly setup.

Pro Shift Kit

Annoyed by lazy shifting? Tired of missing 2nd?

Virtually eliminate missed shifts
  By decreasing friction, shift are easier to make.
Make your twin shift better than most new bikes.

Easier and quicker upshifts, decreased shift lever travel, fewer missed shifts and quicker downshifts.

This is the kit that makes the difference.
Track and street.

..........................................

In 1-2 hours, you can make your shift mechanism work 10% to 20% quicker (5ms to 10ms) and miss fewer quick or lay shifts.

When you look at quickshifter "kill" duration at 55ms, every upshift you are losing about 1/20th a second. Do 20 upshifts and you lose 1 full second of applied power. 100 upshifts and that's 5 seconds that power is "killed" while the QS is waiting for the shift to complete. (Ever thought about that? :-)

If you quicken the shift mechanism by 10%, you decrease the shift kill time by 10% and that's 1/2 second in 100 shifts - and we could all use an extra 1/2 second....... :-)

 I can't guarantee that you'll drop your lap times by 1/2 sec per 100 upshifts - but - wouldn't it be mentally less effort and cool to make missed upshifts and downshifts virtually disappear?

Note about quickshifter shift kill time:
The STAR shifts QUICKER.
You must set your quickshifter kill time 5mm to 10ms quicker or the shifting will be clunky on the track.

Installation:
1 -2 hours - requires clutch basket assembly R&R to install

Available from Power Tripp and direct from Factory Pro. 

 

   
 
 

Tech notes:

Fuel level controls carburetion richness at full throttle / 3000 rpm and below and at cruise.
Before you say "I don't give it full throttle at 3000 rpm", it also controls overall richness at cruise..... (aka... mileage.....). If your mileage is poor, you should probably try doing a full throttle roll-on from 2500 to 3000 rpm.
The bike should pull, cleanly from 2500 rpm or so, in at least in 3rd gear. The higher the gear, the more correct the mixture has to be.
Using an EC997 dyne System, as are at Factory Pro Tuning Centers, that would have been tested in the usual Step Test range.
CO% should be DEF. less than 6% and likely in the 4% to 5% range for that low of an rpm.
If the bike bucks and stumbles, it's probably too rich and you should lower the fuel level (adjust floats leaner) in 1mm increments to attain best full throttle / 3000 rpm operation.
Magically, your mileage will improve and you'll retain the best midrange acceleration.

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.
