Fastening the engine
Engine mounts
Install the engine with the original ATV bolts this engine was designed for or some equivalent bolts 10.9
grade or higher.
If your vehicle specific application does not require all cases mounts, put a bolt and nut on the empty
mount as the mount’s bolts help the engine case strength.
Chain
This engine runs 520 type chain. Once the chain in place, hold the rear brakes and re-torque the
sprocket bolt to spec.

Carburation
The carburetor sold by Panthera are pre-set to suit your engine. Some idle fine tuning might be
necessary as well as re-jetting to your elevation and temperature utilization.
Refer to the Owner manual jetting table.
Exhaust
Fasten the exhaust with the supplied mounts and spring. For exhaust with a middle joint, use high
temperature silicone in the joint to prevent possible leaking.
Powervalve
The powervalve vent can be run anywhere to flush it down. We suggest running it nest to the radiator
overflow line.

The Panthera CDI does not activate the ATV fan. The fan wire as been bypassed in a way that you can
either have the fan always running by putting the original fan sensor wire (yellow/blue) to ground or you
can replace the head 1/8NPT plug by a equivalent 1/8NPT fan actuator.

Oil
The engine has been shipped empty of oil. Fill the transmission with 1.8L of recommended transmission
oil. As recommended in the break in procedure, transmission should be flushed after first ride to
eliminate all the break in deposit. After the flush, refill with 1.5L of oil.
Cooling
Radiator location
Always have the radiator installed higher than the engine. Fluid level inside the radiator must always be
higher than the engine head.
Liquid filling
Fill radiator and engine with high quality ethylene glycol antifreeze containing corrosion protection
inhibitors specifically recommended for use in aluminium engines.
Cylinder might have some remaining of plating treatment residue. As recommended in the break in
procedure, flush the coolant after the heat cycles to eliminate possible coolant contaminant.
After flush, refill the radiator with recommended coolant.

First start up
Electric start engine
The electric starter has a stronger and faster capability to start the engine that the kick start. We
recommend using a booster battery in parallel of the vehicle battery for the first start to ensure optimal
cranking speed.
Never use the decompressor when using the electric starter. The air going in and out of the
decompressor will only slow down the cranking.
Remember, carburetor might need idle speed fine tuning to keep the engine alive.
Kick start engine
The engine is equipped of a decompressor on the head to make the kick starting easier. It is
recommended to always use the decompressor while kick starting.
Used proper protective footwear to kick start the engine an engine kick back can be dangerous. First
starts are more likely to kick back as engine assembly oil will affect the combustion and will slow down
the rotation speed.
Break in procedure
1- Once the engine is running, raise the idle screw to get a fast (approx. 2000rpm) idle.
2- Let the engine run until engine temperature reaches 85°C.
3- Turn off the engine and let it cool down to 30°C.
4- Flush radiator fluid and fill with new one.
5- Take the engine for its first ride and gently start loading the engine with short pulls.
6- Bring the engine to operating temperature.
7- Let the engine cool down.
8- Flush the transmission oil and fill with new one.
9- Be progressive for the first hour of operation before using the engine to its full potential.
