"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!

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".

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

Direct Replacement "HDJ" emulsion tubes

Factory Pro manufactures replacement needle jets (called emulsion tubes by some) to original factory specs. The needle jet orifice wears oblong in as little as 20,000 miles and is particularly aggravated by "in town", low rpm operation. The result is excessive richness at low rpm that can be partially compensated for by lowering the fuel level. Inspect and replace when required.

These are direct replacement jets, but include the Factory Pro "HDJ" High Dispersement Jet system to better atomize fuel and improve throttle response.

A direct replacement for worn, original items. Accepts standard Mikuni main jets and dynojet jets, our Factory Pro Carb Recal Kits.

2.

Standard drop-in carb kit  

Adds more low-end / midrange, if the proper main jet is selected, more topend power. Easy to install and tune - no slide drilling!

This is the preferred carb kit of most users on
V-Max.com and RM Sportmax some of the premier sources of V-Max information - and - some of the best mc user groups on the internet.


Upgrade note:

If you are upgrading your carbs from a dynojet or other kit that drilled the slides 4.57mm or .180", the original slide holes were:

3.42mm / .138" (thank you, Michael Tjon) or
"about .010" larger than 1/8th inch" or
"just a skosh more than an eighth" or
"a 1/8th inch is better for throttle control than drilled out slide damping holes...."

One repair method:
Fill hole carefully with 5 minute or longer epoxy and redrill with a NEW / SHARP drill bit - Be very light on the pressure or you will pop out the epoxy and have to start over again. Patience!!! :-)

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.
