I have an 04′ with only 60 original hrs on it Ive had a valve lash adjustment done and the only other thing is my carb was rebuilt by a certified KTM mechanic. As for mods the only things Ive done are re-jetted the carb, K&N panel filter in stock air box with lid and 5 Uni vents in the rear of the box, pure polaris/white brothers pipe…………….My ? is it sits more than its used and when I go to start it let it idle for awhile or maybe even ride it a little and when I go to put it away and it sits again for awhile the next time I wanna play with it Im finding lots of oil in my airbox like a quarter of a quart? What is causing this? Any help would be greatly appreiciated
