Air trapped in lowers? Happens on the pike when the air transfer port gets blocked with grease.
You’re mixing two problems there.
1. Air trapped in lowers – causes you to struggle to get full travel. Solution is a tiny zip tie squeezed down the wiper seals. Doesn’t sound like your problem – but give it a go first, as it’s easy to do. Finger nail on the seal, prize it open a tiny bit and then push a tiny zip tie down the wiper seal. If it’s the problem, then you’ll hear a little squirt of air come out.
2. Blocked Transfer port = air gets stuck in the positive air chamber, and can’t get into the negative. This sounds closer to your problem, as they’ll feel all bouncy and po-go like.
Solution is to strip them down, and clean the air rod and get the grease off the transfer port.
