Blown Rear Air Shocks '83 Interstate

Yesterday, I hit a crater (a pothole by the standards here) at around 120 kph. The rear shocks were flattened and I assumed the air had been forced out. When I got home I discovered that the air pressue wasn't all that bad. This leads me to believe that the springs in the upper section of the shocks must be broken. I took the shock off last night and plan on given it a good look-see after work today but in the mean time, do any of you have some thoughts on what I should be looking for other than a broken spring? Also - if it is the spring, it doesn't look like it is replaceable, any thoughts on that? I suspect my next post will be a WTB-air shocks for 83 Interstate. Thanks. Don

The springs might not be broken - just worn out from near 30 years of holding up a heavy bike! :)

I replaced mine with Progressive 416's - see How to remove and replace your rear shocks - and I was surprised to find the bike sitting up a good inch higher, even before I pressurized the new shocks. The old shock springs were just so worn out, they weren't up to the job anymore.

I spent yesteray mulling over my options, my shocks are definitely trashed; I considered buying used from ebay or looking locally but in the end I've decided the Progressive shocks are the best long term, no hassle solution. Ordering tomorrow, should have them on by Thursday. Three hundred and seventy one loonies, on sale, ouch, but I think the right thing to do in the long run. I've already memorized your how-to on this one. :D
