5. FIRST LAUNCH
5.1. Water
1. Remove the cap from the radiator, and fill the cooling system with water.
2. Turn the rear axle manually to remove air from the system.
3. Add water until the radiator is filled to the top and tighten the radiator cap.
! Make sure the system is watertight (especially the hose connections).

Distilled water and a low percentage aluminium-compatible antifreeze prevent corrosion, but
adding antifreeze can be forbidden on some race tracks.
5.2. Fuel
Premium unleaded brand name pump fuel (ROZ 95) is recommended. Standard unleaded
fuel (ROZ 91) can also be used without problems. The engine must be operated with a fuel-
oil-mixture at a 50:1 ratio, i.e. 100ml per 5l (US: 2.56fl.oz per 1gal / UK: 3.2fl.oz per 1gal).
Use pre-diluted fully synthetic 2-stroke racing oil.

We recommend only to use the oil Mobil 1 Racing 2T .
! If you use the wrong oil or mixing ratio, this can cause damage or total loss of the en-
gine
– even if damage is not immediately apparent.
! Ensure that fuel and oil are pre-mixed properly in a petrol can.
5.3. Refuel / System Fill
In order to protect the engine, you should never start or run the engine without sufficient fuel
supply. Before starting the engine, the fuel tank should always be at least ¾ full, and all fuel
lines should be full as well.
1.
Fill the fuel tank with pre-mixed fuel.
2. Blow air into the overflow tank until the fuel line to the carburettor is completely full (a
few air bubbles will stay in the line
– this is no problem).
! Make sure all fuel lines are properly secured and do not leak.
5.4. Control
! Double-check the assembly and the steps for first launch.
5.5. Start Preparation
The XR50 can be started with an external starter or an onboard-starter (if so equipped). Al-
ways make sure the battery is fully charged.
! Normally the engine will start immediately. If it should not start right away, you should
look for errors instead of trying again.
! Never run any starter for more than 5 seconds without interruption.
! When starting the engine with the external starter, make sure you pull the starter off
the nut immediately after cranking. Otherwise the clutch nut and the clutch may un-
screw.
