Carburetor Tuning For Performance - Part 1 - The Challenge
A video tutorial series explaining how to tune or adjust a carburetor for a 2 stroke or 4 stroke engine for performance and horsepower, helped by carburetor tuning software.
Part 1 outlines the carburetor components: throttle valve slider cutaway, needle, needle jet, atomiser, main jet, idle jet, fuel valve, float weight.
The carburetor tuning software: Needle Carb Fuel Mapper™ enables fuel maps to be created - an overview of the carburetor tuning software is provided.
Typical carburetors: Dellorto and Mikuni, but all carburetors use the same tuning process, and all carbs can be added to the software
.
Engine tuning, or carburetor adjustment, provides more performance, horsepower, and fuel efficiency.
This applies to motorcycle, car or automobile engines.

00:00:11.900 --> 00:00:17.500
after investing large amount of time and
money building a new engine... it can all end in failure
00:00:17.600 --> 00:00:21.900
with engine seizure... or even melted pistons
00:00:22.100 --> 00:00:26.000
or the engine simply fails to deliver
the expected performance
00:00:26.800 --> 00:00:29.000
the problem lies with the carburetor setup
00:00:29.000 --> 00:00:32.900
each different engine
requires a different carburetor setup
00:00:32.900 --> 00:00:36.900
for stock engines these are determined in
the factory test lab
00:00:36.900 --> 00:00:39.033
but for a modified engine
00:00:39.033 --> 00:00:43.000
the builder has no way of knowing
what the correct carburetor setup should be
00:00:43.000 --> 00:00:48.200
and without understanding the tuning procedure
the correct setup is never achieved
00:00:48.200 --> 00:00:52.700
in this video series were going
to provide that tuning procedure
00:00:52.700 --> 00:00:56.699
to learn how to safely tune a carburetor
for a modified engine
00:00:56.699 --> 00:00:58.811
and gain maximum performance
00:00:58.811 --> 00:01:03.200
this involves discovering the answers to these questions
00:01:03.200 --> 00:01:05.500
carburetor type
00:01:05.500 --> 00:01:08.500
carburetor throat bore diameter
00:01:08.500 --> 00:01:11.900
throttle valve slider cutaway radius
00:01:12.000 --> 00:01:14.200
needle geometry
00:01:14.200 --> 00:01:16.300
needle position
00:01:16.300 --> 00:01:17.560
atomizer type
00:01:17.700 --> 00:01:19.560
atomizer ring diameter
00:01:19.880 --> 00:01:21.760
main jet diameter
00:01:21.920 --> 00:01:23.760
idle jet diameter
00:01:24.020 --> 00:01:26.680
low throttle idle screw position
00:01:27.000 --> 00:01:28.980
fuel valve diameter
00:01:29.540 --> 00:01:31.280
float weight
00:01:31.760 --> 00:01:34.540
if all these questions are answered correctly
00:01:34.820 --> 00:01:36.980
the engine will deliver its performance
00:01:37.240 --> 00:01:38.400
and you'll fly
00:01:38.640 --> 00:01:41.679
if any of the questions are answered
incorrectly
00:01:41.680 --> 00:01:43.800
the engine will fail to deliver
00:01:43.980 --> 00:01:45.160
or simply fail
00:01:45.520 --> 00:01:49.640
the task is made more difficult
because each component
00:01:49.640 --> 00:01:55.280
modifies the effect of other components
by varying degrees
00:01:56.200 --> 00:01:57.900
this means that there are effectively
00:01:58.060 --> 00:02:00.493
an infinite number of possible setups
00:02:00.500 --> 00:02:03.940
how can we even start to make choices?
00:02:04.480 --> 00:02:07.180
We need a fuel map that can guide us
00:02:07.189 --> 00:02:10.796
This is determined
by the needle and atomiser
00:02:10.800 --> 00:02:13.240
but the fuel map options are
00:02:13.360 --> 00:02:19.459
hidden in an incomprehensible catalogue
of numbers and dimensions
00:02:19.460 --> 00:02:24.100
these dimensions describe the geometry of each needle and together with the atomiser
00:02:24.100 --> 00:02:28.620
the basic fuel map
of the carburetor is created
00:02:28.880 --> 00:02:33.280
but we've never been able to see this map
and without it
00:02:33.440 --> 00:02:37.380
carburetor tuning has always been a fog of confusion
00:02:37.720 --> 00:02:39.731
however that has all changed
00:02:39.960 --> 00:02:42.460
a new software has been developed
00:02:42.470 --> 00:02:46.158
that calculates
every available fuel map for a carburetor
00:02:46.160 --> 00:02:49.400
for the first time outside of the factory testing lab
00:02:49.500 --> 00:02:52.580
the engine tuner can examine in detail
00:02:52.640 --> 00:02:56.000
the fuel delivery curve of their carburetor
00:02:56.000 --> 00:03:01.300
this transforms and simplifies the tuning process
00:03:01.440 --> 00:03:05.980
we can see the exact throttle position
when the needle taper is hit
00:03:06.020 --> 00:03:10.780
problems can be identified
according to the throttle position
00:03:10.940 --> 00:03:16.000
modification can be planned in advance
by running multiple simulations
00:03:16.180 --> 00:03:20.300
if we want to lean the fuel mix in mid throttle
00:03:20.300 --> 00:03:24.100
and increase the richness at high load
00:03:24.109 --> 00:03:27.720
the fuel map can be first designed
in a virtual environment
00:03:27.720 --> 00:03:32.260
perhaps weakening further
across the entire throttle range
00:03:32.680 --> 00:03:36.400
areas of the fuel map can be isolated
00:03:36.860 --> 00:03:43.440
the low throttle region can be fixed so
that our low throttle settings aren't changed
00:03:43.440 --> 00:03:46.200
only the taper is being tested
00:03:46.300 --> 00:03:50.180
so any change in performance is solely due to the taper
00:03:50.260 --> 00:03:52.180
there is no confusion
00:03:52.580 --> 00:03:56.940
the brain is free to focus on all phases of the carburettor
00:03:56.940 --> 00:04:01.000
and the different fuel flow modifiers
that are applied to the map
00:04:01.220 --> 00:04:07.340
tuning a carburetor is no longer a black art
derived from decades of experience
00:04:07.520 --> 00:04:11.420
anyone can now rapidly learn
how to tune their carburetor
00:04:11.560 --> 00:04:14.440
there is a strict procedure that must be followed
00:04:14.440 --> 00:04:17.240
but this will be explained in the coming videos
00:04:17.240 --> 00:04:21.680
along with an understanding of each of
the carburetor components
00:04:21.800 --> 00:04:24.240
and how they affect the fuel flow
00:04:24.540 --> 00:04:27.440
if the correct tuning procedure is followed
00:04:27.440 --> 00:04:31.960
the beginner will be able to safely and
successfully tune their carburetor
00:04:31.960 --> 00:04:35.782
to extract maximum performance from their engine
00:04:35.782 --> 00:04:38.800
you will need the Needle Carb Fuel Mapper
00:04:38.800 --> 00:04:41.700
... without it you have no chance of
understanding the carburetor
00:04:41.880 --> 00:04:44.920
and you can download it from Fuelmapper.com
00:04:45.000 --> 00:04:48.040
and learn how to use it
over the course of this video series
