I am trying to gather clear information from KTM on the common problem of oil leaking from the power valve cover. I am aware of 3 new 2020 300 tpi bikes doing this. Mine has (at least for now) been fixed by my dealer. Another friend of a friend fixed his own (long distance purchase) by isolating the problem to the following parts inside the power valve cover. He removed the one piece 2020 part which had a poor seal and replaced with the 3 piece 2019 parts which sealed better and solved the leak:
SEALING CARRIER 07Part #131307001627Mfg. #54837091100
SEALING ELEMENT BOTTOMPart #131307001420Mfg. #54637107000
Anyone want to shed some light on this?
Sounds like a simple fix that will eventually lead to a recall.

The problem is fixed for now by my ktm dealer but not exactly sure what they fixed. My more technical distant friend who had the same issue and he worked through a solution on his own. He claims the issue is with the sealing element under the power valve cover. Very easy fix and inexpensive. Apparently the 2020 motor went to a one piece seal replacing the 3 component 2019 and it is too loose. You just need to buy the following parts for the 2019:
Sealing carrier 07
part #131307001627
mfg. #54837091100
and
Sealing element bottom
part #131307001420
mfg. #54637107000
These fit way more snug and it fixes the problem. You may also want to get a new power valve cover gasket. Overall, less than a $20 fix. It's a real bummer KTM/Husky isn't sharing info on this known problem.

Apparently on the 2020 models it’s just one piece but the 19’s it was 3 piece? I ordered all 3 pieces but I’m also going to try some grey rtv
