Harder, or softer rear suspension for washboard hills?

[Bill Hilly]

I like running the back roads, but I hate them long winding severely wash boarded hills. With a full face helmet, my head gets shook around so bad that it's hard to even see. I have even felt like it could be harmful to a person, kind like what they call "shaken baby" syndrome. I have the stock adjustable shock on my TBR7, and a similar one now on my Hawk that I bought online. I think it's probably what comes stock on the DLX. I have my Hawk set harder than the TBR7, but both bikes shake me to the core on the washboard hills. I don't mess with lowering tire pressure on my rides , because I want to minimize risk of tube issues, but I would like to at least set my shock up right. I weigh around 250 lbs. Should I go with as soft as I can get by with on my rear shock, or as hard as I can stand ?, Or does it even matter, I figure that with my weight, and the fact that more weight is transferred to the rear going uphill that the rear shock is probably compressed pretty good.

Stand up on the pegs.

There is no perfect solution for that scenario. You can try to find a good spring rate that allows travel without bottoming out, and then getting a shock that dampens just enough not to pogo stick the back end, but there is a lot of math and some experience required to really get it dialed in.

I am close to your weight and a 1000lb/in linear spring rate is the best I have found. The rear setup I use is a Fastace, but it would be way too short for a stock tbr7 swing arm. Even on a Brozz swing arm it lowers the bike a couple inches out back, which is what I wanted.

Edit: I should also add that lower tire pressures can also help a little and take some of the sharpness out of the impacts.
