Greetings Peter,
Initially you should be able to download a manual for both KTM models of motorcycles from the following link;
http://www.ktm.com/us/service/manuals/If I might explain motorcycles that store their engine oil in the engine sump are known as 'wet sump' engines and those that store their oil in a separate oil tank or in the frame are known as 'dry sump'.
The oil pump on wet sump engines has a single action which is to force oil to the various locations that need lubrication or require oil to be squirted for internal cooling and non pressurised surface lubrication. The oil pump on dry sump engines is in two sections, the first acts to force oil around internally to lubricate and cool - plus a slightly larger capacity but lower pressure section which returns the oil back to the external storage area.
Generally dry sump systems 'leak' a little bit of oil through the oil pump gears overtime whilst the engine is not running. This oil collects in the sump section and has to be pumped back into storage and this takes a little time to do so, hence you can only really check the oil level after the engine has run for a given period of time. However, as a guide so that you can tell how much oil has drained down some engines are fitted with a spy glass in an engine case.
I hope that these comments help explain the basic differences between wet and dry sump systems. If you need further guidance then please do not hesitate to ask and it will be our pleasure to try and help out
TTFN
Hugh.
