Hello all. I've got an 07 KGT with about 65k miles. At some point in the bike's life, the cam chain tensioner was replaced with the upgraded BMW unit (Black cylindrical unit). I've owned the bike since it had 40k on it without any issues however, I'm going to have to leave the bike sit for 8 weeks very soon. I'm strongly considering replacing the cam chain tensioner with a manual unit from APE or PSR before I leave because I'm nervous that the factory upgraded hydraulic unit will dry out. Are my fears reasonable?
