th row too m an y surprises at you . Get
included in the kit, except tools. Even
By BLAKE CONNER
First things first, you either need to
have a basic understanding of motorcycle design, have the shop manual ,
or both . If you haven 't worked on
your bike before, the shop manual
will save you at least an hour. Most
Japanese bikes are very similar in
basic des ign , so if you have worked
on a Honda , a Yamaha isn't going to
all t he tools you will need handy. If
if you aren't the best mechanic , this
ket exhaust pipe on your ca rbureted
job isn 't really that hard . It just
motorcycle, and the bike isn't running
as crisply as it was , you most likely
requires that you are good at follow ing directions, and have the proper
need to install a jet kit. T here are a
couple of companies that make jet -
tools . If you have a friend who is a
good mechanic , it wouldn 't hurt t o
kits , but for this project we chose a
D ynoj et -brand jet kit. Everything you
invi t e them over.
you have a race stand, put the bike
up on that, it will make the job easier.
We installed the jet kit on our 2000
Yamaha YZF-R6 , but the basic procedures apply to most bikes out there.
The job will most likely take about an
hour to an hour and a half.
STEP 1
STEP 3
Remove th e fuel tank - noting where the breather hoses and the fuel line
attach , and then unhook them . The R6 has a hidden petcock on the bottom right
of the ta nk, be sure to turn this off. If you have an old tire lying around , it makes
a great p lace to set your tan k down , which w ill protect it from getting scra tched
and the pe tcock from getting bent.
Removing the carbs is the single hardest part of the job. It takes a little
patience, combined with a knowledge of where the A llen-head bo lts reside on
the collars that secure the ca rbs to the int ak e ma nifolds. On the R6 , the bo lts
are v irtually hidden betwee n eacf carb and have to be accessed from the front
of the carbs - you will need a flashlight. (see below) Th e exception is the #4
c ar5 (riders right) , whi ch c an be accessed through the frame side-cover. A ft er
you Have loosened -up all of t he bolts that secure the carbs to the in take ma ni fo ld s, unhook the th rottle cab les an d toe choke c abl e.. T hen unhook the coo lant
hoses th at are routed througfi the carbs . have a ra g re ad y , because coolant will
come streaming out.
