Okay, I know I could solve this myself, but i don't have an owners manual. I weigh 155' Wifey weighs 98' the ride with Wifey on board is excellent. It's just the tiniest bit soft, but she's comfortable. By myself though, I get launched out of the seat a TON! I do like it a little on the stiffer side, buit it's a two hour comute and I need to compensate for the ply wood seat. Which adjustments, and how much of an adjustment, do I need to make on my 2004?
