Yeah, I had ProAction do the suspension. You might remember the guy - I think his name was Chris? Well known guy in the community, but died of cancer way too young. Probably around ten years ago.
Anyway, yeah progressive spring in the rear. Resprung and revalved for 195 lb intermediate rider (me) but I’ve got the original springs in a box.
SX head is a great mod for these bikes. Adds a ton of low-end grunt. Only problem was that the extra compression was too much for the stock starter/battery to handle, so had to install a lithium batt for a bit extra oomph. Works great and lost a couple pounds too.
Have had way more interest than I was expecting. Guy is driving up from Calgary tomorrow to look at it, so I expect it will be gone soon. Thought the market was still soft, but I guess not. Priced it at $4,500 last year and didn’t get a single bite. That was on kijiji though, so maybe that was the problem, not the price.
