Inertiaman - 1 year ago we had not touched an FJR at the shop. We had depended completely on R&D from a guy setting up lots of FJRs out on the west coast. When I bought an FJR in November of last year, we started right away doing the R&D on it. The guy we worked with out west is a knowledgeable tech but we feel he was going by sag numbers completely.
I weigh 210 without gear. The first spring I tried was a 950. I had considered trying a 1000 lb spring but we had none at the time on the shelf. So, I put the 8981 on the bike with a 950. Sag numbers fell right in line using the standard preload numbers we have for that rate spring. The ride was harsh to me while riding alone. It was a bit harsh when I rode with my wife. So, I tried an 800 lb spring with a little more preload. It was fine while riding alone but 2-up, it was a bit soft. At that time we decided the 850 should be the standard for a 200 lb rider doing mostly 1-up riding with occasional riding with passengers. The FJR is a heavy bike so 50 lbs difference either way with that stiff of a spring is not going to make a huge difference. The FJR is one of those bikes that perfect sag numbers does not work well. When I say perfect, I am referring to our standard baseline in the shop for testing or R&D BEFORE a test ride. Those numbers are 10-15 mm static and 30-35 dynamic. The FJR rides better when the sag is a bit on the high side.
If you call the shop and ask for me (Lee), we can get your harsh ride resolved. It won't cost you anything but a phone call.
I am out of the shop for the next 4 days. I'm heading to Deals Gap tomorrow for the fall FZ1 mini rally. I'll be back on Monday so that'll be a good time to call me.
Give us a chance to make it right. You won't be disappointed.
