KTM WP oring update...
The newer 990's were updated with a different wp oring made of viton ( or another manufacturer of the same material, as viton is a Dupont product). And this seal is what they recommend to replace all older wp seals with.
I managed to get this info from a KTM tech customer rep from Ohio recently.
One of the customer service advantages of being a original owner of a KTM Adventure is any KTM shop, KTM service rep or customer service rep can check the history of your bike, explain any service updates and status reports on your bike based on their database.
Since my bike was an '04 S they are researching to make sure I don't have the noisier '05 version of torque limiter.
