Triumph's ground-breaking Daytona 675 has not only received global recognition for its
performance on the road, but also for its outstanding ability on the race track. To further
support this exceptional track ability, Triumph have launched a Racing Support Programme,
which is now further complemented by the launch of a range of Triumph Genuine Race Parts.
Factory developed in collaboration with Paul Young Racing, these parts have been designed
to give significant improvements in engine performance for race purposes. This results in
the class-leading Daytona 675 being competitive on the racetrack at the highest level.
Triumph Genuine Race Parts are sold individually and a number of the parts need to be used
in conjunction with each other to ensure the best performance gains are realised and also
to prevent premature wear on associated components. Please ensure you read the user
manual in full to understand this detail prior to fitting or using any of the Triumph Genuine

• The race kit valve spring must be used in conjunction with the standard
spring platforms and retainers. The fitted length of the race springs is the
same as the standard spring.
1.The race kit valve springs should be
assembled in the same manner as the
standard valve springs. Follow the
procedure detailed in section 3 of the
Daytona 675 service manual. Ensure
the springs are installed with the close
wound, colour coded end of the springs
facing downwards, towards the piston.
2.The race kit camshafts should be
assembled in the same manner as the
standard camshafts. Follow the
procedure detailed in section 3 of the
Daytona 675 service manual.
3.The race kit cam sprockets should be
mounted and secured to the camshafts
using the slotted holes in the sprocket.
The slotted holes allow adjustment of
the valve timing. The circular holes in
the sprockets are for Triumph service
tool T3880102 and should not be used
to mount the sprockets to the
camshafts.
5.Always check the inlet and exhaust
piston to valve clearance for the timing
selected to use, before running the
engine. You must ensure both
clearances are adequate. As a guide,
the standard nominal piston to valve
clearance is 1.3mm inlet & 1.5mm
exhaust.
6.When the desired timing has been set
the new socket retaining screws
provided should be tightened to 15Nm.
Note, if the screws are released for any
reason, apply ThreeBond 1305 to the
threads before re-tightening.
NOTE
• No timing marks are included on
the race sprockets. Race engines
will typically have different depths
skimmed off the cylinder head and,
therefore require specific
individual timing.
4.The camshafts should be timed using
cam degreeing equipment which
typically consists of a degree wheel,
pointer, dial indicator and piston stop.
Optimum cam timing will depend on the
exact specification of the engine, but a
recommended starting point is 104
IMOP (Inlet Maximum Opening Point)
and 104
5.Lightly coat the large O ring with oil,
install the new tensioner assembly and
secure with the new fixings provided.

same material and have the same mass as the standard valves.
1.Remove the existing inlet and exhaust
valves following the procedure detailed
in section 3 of the Daytona 675 service
manual.
2.The valve seat widths on the race kit
valves are narrower than the standard
valves, therefore the bottom angle
o
(120
) of the cylinder head valve seats
must be modified to ensure the seat on
the head matches the seat on the valve.
3.Check the head seat and valve seat are
matched correctly by applying
engineers blue to the cylinder head seat

The race ECU MUST be used with the following race kits; A9618055 Camshaft - inlet,
A9618056 Camshaft - exhaust, A9618057 Camshaft sprocket, A9618058 Valve spring,
A9618063 Air Funnel and A9618071 Race harness.
NOTE
• The race ECU will only work with the race harness A9618071, and production
instruments fitted.
• The race ECU is pre-programmed for use with the following set of race kits;
Inlet & Exhaust camshafts (set to IMOP 104
sprockets), Valves, Air filter, Air Funnels and Arrow Stage 2 exhaust system.
The tune has been developed to suit a compression ratio of 14:1 with
enlarged and polished inlet ports and the exhaust ports modified as
recommended on page 16. However, due to variation between race prepared
engines fuelling adjustments will be required.
• The tune is for a rubber fuel hose only, Triumph Part No. 1240177, it is NOT
suitable for a plastic fuel hose.
• The Air & Fuel ratio should be checked and any adjustments to the fuelling
setting should be made using a third party programmable control unit.
• The rev limit on the race ECU has been increased by 1000rpm over standard.
• The indicated speed shown on the instruments is calibrated for the first gear
pair and housing race kit (A9618066). If the standard gearbox is used, or the
final drive ratio is changed, the indicated speed will be incorrect.
• Idle speed should be set to between 1,500 and 1,800 rpm.

• This will flash a sequence of error codes if any faults are present.
• Flash codes have a long flash for the first digit and a short flash for the second
digit. For example; Fault code “32” would be: long, long, long, short, short.
• When a fault has been identified and rectified, the ECU can be cleared by the
following sequence: Full throttle, ignition ON; flick the kill switch off/on/off/
on/off.
Caution
No ECU faults should be present during motorcycle operation. If the motorcycle is used
with ECU faults present it will be operating in default “limp home” mode only which will
produce inconsistent operation.
• The race harness will not work without the Race ECU A9618070.
• The relay and fuse box position has changed on the race harness for ease of access and
maintenance. They are now located alongside the battery, under the seat. Ensure they
are secured in position so they do not suffer from vibration problems.
• The race harness does not support all of the OE equipment, therefore, the following
components can be removed from the motorcycle; Oxygen sensor, Exhaust valve, Idle
speed control, Secondary air injection (SAI), Purge control (California only), Lights and
Air intake flap solenoid. The SAI ports must be blocked off if the system is removed.
The throttle body purge ports must be blocked of before use (California only).
• The race harness still supports the cooling fan and incorporates a relay for the fan. You
may remove the cooling fan but must leave the relay in place.
• The race harness does not support the idle speed control motor and therefore, this may
be removed from the throttle body. It is recommended to use the manual idle speed
adjuster A9618076 to replace the throttle stop screw when using the race harness.
Throttle body balance should be checked if the ISC cam is removed from the throttle
body assembly.
• The race harness is suitable for use with both the standard and race kit Alternator. It is
recommended to always run an Alternator, without it the battery will discharge in a
very short period of time.
• The combination of the race ECU and race harness allows the ability to have ignition
cut for “quick shift”. To use this feature connect a suitable 5V 2mA switch to the
supplied connector and mount the switch in a convenient position. When the switch is
pressed the ignition will cut for 40ms.
• If the quick shift function is not going to be used, leave the harness connector blanked
off to avoid possible short circuits.
1.Apply silicone sealant to the mating
surfaces of the Carbon fibre cover and
corresponding engine cover. The
recommended sealant is “Impact
Adhesive 5255” (or direct equivalent)
which is a high temperature, chemical
and environmental resistant sealant.
