6.3. Driving
With the XR50 you will be quicker than most other karts on the track. Have fun, but be con-
siderate of other drivers and never drive faster than your skills and experience allow.
Try to develop a smooth driving style. Brake early, build momentum with high apex speeds,
and accelerate early from corners. This is much quicker than braking and drifting hard.
! You will have to get used to the performance of the engine. Slow down if you feel that
you do not have full control over your kart.
! Due to the higher speed you will have to brake earlier.
! Make sure you do not accelerate and brake at the same time and that you do not let
the clutch slide, as this may overheat the clutch and wear the friction discs very
quickly.
! Pay attention to the fuel level, and make sure you do not run out of fuel.
While driving, make sure you run the engine within the optimal operation parameters:
6.3.1. Engine Speed
From 2008 all XR50 are equipped with a rev limiter. Still you should adjust the transmission
ratio to keep the maximum engine speed below 10700rpm.
! Make sure the rev limiter does not or hardly engage.
! If you have an earlier model of the XR50, have the ignition replaced to protect the en-
gine from too high speed, as this can lead to engine detonation (flying parts can cause
serious injury).
6.3.2. Water Temperature
After heating up the engine, the water temperature should be 65..75°C (150..170°F).

If the water temperature is too low, you can mask part of the radiator with tape. If it is too
high, the radiator may have too little capacity, or there may be a problem.
! Do not run the engine with too high water temperature, as this may lead to engine
damage.
! If you observe a strange water temperature (e.g. significantly lower than usual), the
cooling system may have a leak. In such a case stop the engine immediately and
check the cooling system when the engine has cooled down.
6.3.3. Main Bearing / Transfer Port Temperature
The transfer port temperature swings significantly while you are driving. It should never ex-
ceed 140°C (285°F).
! If the temperature exceeds 140°C (285°F), stop the engine as soon as possible and
check the engine or have it checked, as this indicates a bigger problem (e.g. housing
leak, insufficient lubrication).
! Note that the maximum temperature is typically reached under braking after long
straights. As you will not always have time to watch your data logger in this situation,
also check the engine temperature after every session.
