I’ve stripped down and rebuilt my 55 ATAs. I took the rebound/compression pistons out the TST2 cylinder to check o-rings etc.. all looks like new still. I then refitted it, leaving the top cap unscrewed, and squirted new 7.5W oil down into the lower, as per spec.

Question is, how will oil get into the TST2 cylinder ? There’s no info anywhere about oil levels within the cylinder – surely there won’t be any damping if there’s only oil sloshing around in the lowers ? 😕
