Massive difference between a .91 and a 1.27. Remember it's not just about the spring change, have to revalve as well. Otherwise suspension is too hard at low speeds and too soft at high speeds
It ended up being a 14mm which surprised me. My FZ-10 was a 16mm iirc. With the Helibar riser on there I couldn't get a good look at it so I just assumed it was bigger than the sockets I was trying.
Anyway I added one full turn of perload and two clicks of rebound. I may add another half turn of preload and see how that feels. I used Motojitsu's youtube video to set the front preload. I rode to work this morning and didn't even think about the front end until I got to work. which means I'm in the ballpark. So I'm a bigger guy, 6'3" 240lbs. According the RaceTech's website I'm just about within the weight rage for the rear spring. The front stock spring rate is 0.91kg/mm and they are recommending a 1.27kg/mm to1.31kg/mm. I understand what that ratio means but not exactly how big of a difference there really is between a 0.91 to a 1.27 for example. I'm not a drag racer and I do run the twisties about every weekend.
I used to ride my 2002 Blackbird in ways that made the guys on 954RR's and the like surprised that bike could do that. I may do the odd track day in the future but not likely.
