On my old r1150gs after 40,000 miles the standard shocks were tired . I bought a used set (to keep the bike on the road) and the used set were overhauled bu ABe and fitted with Hyperpro springs . Huge difference and the shocks were more than good enough for the road
yes.. still thinking of a Hyperpro progressive spring on the stock shocker... how did they transform yours?... less harsh on the bumps but still as firm is what I'm after

but admit I miss my Harley grin so much, and just taking it to bits was also loads of fun.
Interesting theory, now to explain that to the other half.......
nearly spat my coffee out, bump it up to 38 go ride solo, and you will have your answer for sure......
pop some fairy liquid on the valve, could be valve not tight.
