If i had to adjust my valves as often as you do with that ktm im sure i can do them in 20 min's too!
My comment was based on trying to find parts 4 years ago when i went to purchase a new bike, and from my experience of friends with ktms, and my experience with having to drag one heavy a$$ 4 stroke out of the big bowls of glamis! I have had no problems with my Jap bike.. it has treated me just as well as i treat it.
