Well, I think it's time for an update on this thread.

As I mentioned before, James spent countless hours trying to figure out the issue - well he was right.

I brought my KTM back to Tahoe a couple weeks ago and I finally had the time to take the engine out and look at it more carefully. I redid a leak down test just to be sure and there was enough air going out of the exhaust port to blow my hair. Well, the little I have left.

Turns out there is a pretty significant hole in the exhaust valve! I haven't removed the head yet but you can see it quite cleary from the exhaust port.

So that would probably explain the problem he has been having. I have no clue what may have caused that. The bike only has about 13000 miles on it.

So now the question is - what's next...

Do I spend more time learning about this engine, remove both heads and send them over somewhere?

Do I send the whole engine and let someone more qualified take over?

Does anyone know of a good shop in the Bay Area or Reno area?

thank you - I hate when threads don't have a conclusion so hopefully this may be useful to someone one day.
