Anyone have a service manual for a 2005 or 2006 to 2012 FJR1300? I have one for my 2014 and am trying to get some info on front forks. Really don't want to buy a bunch of service manuals that I won't use again. If you have one, would you please look up any of the items below and pass them on.
I am trying to compile some data to compare Gen III forks with older models. I know there are some significant changes going on here but would like to get some numbers to help figure some things out. The K1/K2 data is most significant because it tells you a lot about the progressive nature of the springs. The information I'm looking for is in the service manual for each particular year. I'm not sure if it is consistent across all of a Generation. I know springs have changed because compression and rebound adjustments are both on the left fork. Not sure if that makes any difference but it is a change with Gen III. Free length, K1 and K2 numbers are significantly different between what data I did find on Gen I and Gen II forks compared to Gen III. The following is what I have from my service manual. I'm trying to get a representative sample from Gen I, maybe a 2005 and early, middle and late Gen III's; like 2006, 2008, and 2010.
Thanks in advance for any help you can provide.
Gen III has:
Trail 109 mm
Castor 26 degrees
Wheel Travel 135 mm
Fork Travel 135 mm
Spring Free Length 345 mm
Limit 340 mm
Spring Length 322..8 mm
K1 rate 0.85 kgf/mm
K2 rate 1.02 kgf/mm
K1 stroke 0-67.5 mm
K2 stroke 67.5mm - 135mm

Per my service manual labeled: 2009-2010
Trail 109 mm
Castor 26 degrees
Wheel Travel 135 mm
Fork Travel 135 mm
Spring Free Length 262 mm
Limit 257 mm
Spring Length ??? ?
K1 rate 0.85 kgf/mm
K1 stroke 0-135 mm

Manuals on disc are a few dollars on Ebay.

Thanks Eric
Banjo, I may have to go that route. I've already got inconsistencies. For example, Gen II 2006 has different rate than Gen II 2009/10. With no K2 figure and a stroke of 135, 2009/10 it implies use of a straight rate springs, which I doubt. That means I'll have to get 6 or 7 manuals to figure out Gen II alone, then the "few dollars" start mounting up.

Thanks guys. I now have digital copies of all models from 03-14 except the ES. KJ at www.repairmanualguru.com fixed me right up. It even has a supplemental for Gen I's.
Bottom line is Gen I's have dual rate springs, actually 2003 and 2005 are different rates. Gen II has straight rates at .85 which is IMO a tad light. Gen III is dual rate again at different rates and strokes than Gen I.

Glad you found the information you were looking for. I never gave much thought about what springs were in the bike.
I know our Goldwing had progressive springs (way under sprung) until I changed them out (did that make a difference!!), and I may upgrade the front springs on the FJR with beefier springs if I mess with the suspension...

Right now my stock shock is sitting on the floor next to my bike. HyperPro fully adjustable should be here next week. FJR shocks were a poor design for all years but they beefed up the Gen III's. Just wanted to check out if they really did anything to the Gen III forks as well. They did, but I wanted to be sure. Getting solid info on some of the forums is shakey at best, that's why I went to a service manual search. My instincts say the forks are probably ok, except needing some tweeking of adjustments. Shock is another story all together. I will be commencing test flight in March or April, or whenever the salt, sand, and crap is washed off the roads down here.
