Checking the coolant level

The coolant should be 10 mm (0.4 in) above the radiator fins when the engine
is cold (see diagram). In the event of the coolant being drained, always fill
and bleed the system.
If possible, always check the level of cooling liquid when the engine is cold.
If you have to open the radiator cap when the engine is hot, use a rag to cover
the cap and open slowly to release pressure.
Bleeding the cooling system
By removing the screw [1] at the water pump cover you can drain the coolant.
To bleed the cooling system, add coolant up to approx. 10 mm above the radi-
ator fins when the engine is cold.
After a short ride, check the coolant level once more.

Cleaning the air filter *

The air filter must be cleaned prior to each race or whenever dust has accu-
mulated. To clean, lift the filter box cover
(see illustration) and pull off towards the front.
Detach the bottom of the filter retaining bracket [2], tilt aside and remove
the air filter [3] and filter support [4] from the filter box.
– Do not clean foam filter with fuel or petroleum since these damage the
foam. KTM recommends the products of the company Motorex for air fil-
ter maintenance (Dirt Bio Remover and Liquid Bio Power).
– Never start your motorcycle without any air filters. otherwise, dust and dirt
may penetrate and cause damage and increased wear.
– Dust and dirt can accumulate and damage the engine if the air filter is
not mounted correctly.
Thoroughly wash the air filter in special cleaning fluid (Motorex Twin Air Dirt
Bio Remover) and allow it to dry well. Only press out the filter, do not wring
it out under any circumstances. Oil the dry air filter with a high-grade filter
oil (Motorex Twin Air Liquid Bio Power). Also clean the air filter box. Check
the carburetor collar for damage and that it is filled correctly.
Place the air filter on the filter support and insert both in the center of the
filter box. Hold in place with the filter retaining clip.
