Your carb needs to be cleaned. More specifically, the pilot jet, but if it's clogged it'd be best to go ahead and clean the whole thing.

Remove the carb from your bike and then remove the bowl from the bottom. You'll then be looking at the jets and float valve. The jet causing your issue is the smallest one. Remove it and carefully spray it out with carb cleaner. Then hold the jet up and see if you can see light through the hole and that it appears clean and round-meaning no obstruction left. Locate the mixture screw on the outside of the carb. It should use a flat screwdriver. First turn the screw in and count the number of turns. Then remove the screw, followed by the spring and ,if applicable, a small o-ring. Spray through the hole and make sure it goes through and comes out somewhere. Replace the screw in the reverse order and set to the original setting you counted in the beginning.(rough estimate is 1.5 turns out. Cleanliness is the key to the carb working. So keep it spotless inside and reinstall. This should take care of your problem.

Possible you have a cracked case or a gasket protecting the gearbox, or some external oil-seal has failed

The water is getting past the water pump seals and into the gearbox. New seals are needed.

08 needing recharged? if it needs recharged it probably needs new seals. it's cheaper to send it to http://www.factoryconnection.com/index2.htm than to take it to a dealership or buying the equipment needed to do it yourself $$

an alternative......convert it from pds to bladder and make rebuilding easier

There is a local KTM dealer here where I live. The number is 904-247-1622, I've been there and they seem to be really nice people and will work with you.

Call 904-247-1622 They are a KTM dealer.

That would be like riding a fixed wheel bike.Think about how you will stop and start. Only hydraulic fluid will leak. Bad idea!

Question edited for clarity. That sounds like it is just a bad connection somewhere or possibly a bad switch. Remove the battery leads and clean the lead contacts and battery posts with a wire brush. Smear with Vaseline and reconnect. Remove the starter leads and do the same. Then it could be the Starter Relay https://www.google.com/search?q=ktm+450+sx-f+starter+relay+location Or Starter Button https://www.google.com/search?q=ktm+450+sx-f+starter+button+replacement ..

personnaly I would replace cylinder with new OEM

All dirt bikes have a VIN. It is on the steering neck. https://www.google.com/search?q=vin+on+my+ktm+300 ..

Have you checked battery connections. Run switch in the correct position? Checked spark plug for debris? Just thinking out loud..

Drain oil. Use degreaser to clean area. Use JB Weld & allow to set up properly before adding oil.
