SAFETY GUIDE
Always wear a helmet, neck support, driving suit and gloves while operating. Never
drive on public roads, highways or any place other than a sanctioned racing facility.
Karts can cause severe injuries, paralysis or death to the operator or others. Owner
assumes all responsibility for safe operation of the vehicle.
KART INSPECTION
It is the owner’s responsibility to carry out regular inspection of the kart components,
brakes, steering, etc. All steering components should be properly fastened and safety
clipped: steering shaft, tie rods, spindles and kingpins. All braking components should
be properly fastened and safety clipped: master cylinder, brake rod, brake caliper and
brake rotor. All nuts holding on wheels should be locking nuts. All nuts holding on
bodywork components should be locking nuts: front bumper, nerf bars and rear
bumper brackets.
KART MODIFICATIONS
Under no circumstances does Margay Racing authorize or recommend modifications
of any type to the chassis or components we manufacture and distribute. This
includes alternative methods of component assembly, chassis manufacturing, etc.
Altering the chassis or components is solely the responsibility of the owner.

GENERAL MAINTANENCE
Below are a list of items to keep your new kart running at maximum efficiency:
Change oil after Day 1 break-in (30 min),
and every 2 hours following with 14oz of
4T engine oil (any brand).
Ensure front and rear sprockets are aligned
for a smooth chain. Lube chain before every
run with chain lube or a 90w gear oil.
Tension should be loose enough to show 2-3
teeth when pulled up on.
Lube between bearing wall and dust jacket
before every run with Tri-Flo or WD-40. Avoid
the use of white lithium grease.
Inspect and clean clutch components with
brake clean and emery cloth after every
2-3 hours of use.

GENERAL MAINTANENCE (CONT)
At the completion of each days racing
sessions, be sure to pull the carburetor drain
plug screw to empty the float bowl. This will
help limit required maintenance on the
carburetor in the future.
Remove the float bowl on the carburetor and
break clean the brass jets that are screwed
into the housing. This will help ensure your
engine is running at the optimum level.
Check and tighten the axle bearing set
screws after each on track session. This helps
ensure that the axle stays in position and
doesn’t move under load on track.
Check header bolts after each run to ensure
they are always tightly fastened. Also check
header mounting bolts, brackets, silencer,
and silencer clamp.

DRIVING LINE AND TERMS
Oversteer is when the rear of the kart
slides more than the front, causing the
driver to counter steer to avoid spinning.
Understeer is when the front slides more
than the rear, causing the kart to ‘push’
forward instead of turning.

TIRE PRESSURES
Tire pressure starting points (set before going on track):
Hoosier R55: 10 –12 PSI
Hoosier R60B: 12 –14 PSI
Hoosier R80: 14 - 20 PSI
Setting tire pressures for a cold tires is done so the tire can reach maximum
temperature near the last 25% of the race. It is important that you set tire pressures
cold with values that discourage them from becoming too hot during the session.
Using air, each tire should not rise more than 4 PSI during a normal session. We
recommend you check your tires after each session to ensure that they are not
overheating.
PROBLEM: The kart gets better as the race goes on, but by then it’s too late.
SOLUTION: Increase the tire pressures by 1 PSI per session. This will help get the tires
to temperature faster.
PROBLEM: The kart is really good in the first 3 laps, but gets slower from there.
SOLUTION: Decrease the starting tire pressures by 1 PSI per session. Your tires are
getting to temperature too quickly and are likely overheating from there. Decreasing
the starting pressures will allow them to heat slightly slower, making the kart become
progressively better instead of progressively worse.
Cold tire pressures can vary based on ambient temperature. On a cold day, increase
starting tire pressures. On a hot day, decrease starting tire pressures.

WHEELS AND TIRES
The relationship between wheels and tires is an important one, both for handling
and overall performance. The recommended wheels for the Ignite K2are:
#771311 TruSpeed 130mm DSM front wheel / for 4.5 front tires
#771310 TruSpeed 130mm rear wheel / for 4.5 rear tires
The phased out DWT AlumiLite wheels will be allowed for use in the Ignite series for
the 2020 racing season only.
Balancing tires each time they are mounted on the rim is important to ensure that
all rotational mass is properly balanced.
PROBLEM: The front tires are shaking at the end of the straight sections.
SOLUTION: Your front tires likely need to be balanced. Use stick on wheel weights to
ensure that the wheel/tire combination is properly balanced.
PROBLEM: The kart has too much overall grip.
SOLUTION: Switching to the DWT AlumiLite wheel set will help the kart lose some of
its mechanical grip. Maintain the same wheel widths will ensure a true back to back
comparison.
The Ignite Series uses a spec wheel width and type for each class. Please refer to
the Ignite Series rule book for more information.
