The 79 A1 has been running S&W air shocks. The left has a blown seal, and while it's possible to replace the seal...
Why?
Certainly modern shocks are better now?
Ordered these from YSS.
They should arrive in about 5 weeks.
Fully adjustable - Threaded spring preload, fine-tune rebound clicks, and multi-position compression damping.
They even have different spring rates available.
This price is in Australian dollars. USD from Traxxion Dynamics was $900.
Also bought a shock for the 81 CBX.
I'll post up when they arrive.
