Thank you for your reply.
Yes, I agree OEM is best. However, lokal dealer did not supply new Orings when I ordered new carbonring-kit, and needs 2 weeks(!) to get them for me.
Would be nice to do a testrun before winter kicks in :banghead:
Guess I'll order them online from elsewere, none of the rings I have did fit.
PS: love your youbtubevideos!
