"Long Boy"

Finger and screwdriver adjustable extended Fuel Screw

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.

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".

Fuel screw set comes with:
4 Long Boy fuel screws
4 new o-rings
4 new washers
4 new springs

For 1200's with Mikuni carburetors.

Hello Marc,

For two years ago I have ordered in the Netherlands the CRB-TD12-1.1-TI kit for my Daytona 1200. ('95-60.000 km)

The problem before was, no smooth at lower rpm and in cold condition it was necessary for at least 10 minutes to use the choke. The information about this I found on your site. Never heard before about emulsion tubes who are worn. I removed them, then looked to them with help of a magnifying glass and I was wondering about the wear of the tubes. The same as the pictures you showed on your site!!!!

After installing the kit, everything changed. Smooth everywhere, decreased full-consumption, increased power, the choke was a great help the first ten seconds, after this period, not necessary anymore. A great solution.

For two weeks ago I ordered for the same bike an ignition advancer but they send me the wrong, it was the advancer for the three cylinder. No problem, I have more Triumphs and installed it on my '95 T-bird (60.000 km). Ha, ha, it helps really. Increase of power and.......... from 2nd to 3rd gear a wheelie, for the first time since 13 years!!!!

Thanks again!!!

Needle jet / emulsion tube

$132 set of 4

1. Choose your shipping method


The stock Triumph 1200 needle jets (incorporated into the top of the emulsion tube on the 36mm Mikuni carb) wear out in as little as 8000 miles of "in town" driving on Mikuni carbs, causing excess fuel delivery that cannot be compensated for by lowering the fuel level. Generally, if your bike has 10,000+ miles and the mileage is very poor, the needle jets / emulsion tubes are the first thing to replace to get back to "like new" mileage.
Check out emuworn.html for more needle jet wear information.

Hi Marc,

I have installed the kit. The Sprint now screams ( as loud as a Sprint can anyway).

Thanks for making the kit. You may want to contact Jack Lilley ( the UK. They were not aware that you made a jet kit for the Triumph's. Also, some of your distributors (Tucker-Rocky) did not list the kits for the Triumphs.

Thanks again,
Jeff Greene

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.
