I upgraded my fork springs this weekend. I bought the set from another member.

They are the Ohlins 1.05's that Jaws sells and they are really a big improvement. These springs are about 100mm longer than the stockers with shorter spacers. I was short on time so I just installed the springs and spacers. I'll finish going through the forks this winter.

I ended up with about 50mm sag, but it still feels much better. I've heard that 35mm is a good number to target. What kind of sag are you other guys running?

No comments on the sag numbers?

Is this static sag or with you on the bird?

That's with me sitting on the bike.

I shimmed my stock springs for 1 and 1/2" of sag. Big improvement.

50mm is too much.

I'd go no more that 40mm. Mine is 37mm and feels good, but I've also got the RaceTech compression and rebound valves fitted. Air gap is important too. What have you got that set to?

A good rule of thumb for any motorcycle. Sag (with you on the bike) should be 1/4 of total suspension travel.
On the Blackbird, that is just under 1 3/16" or about 30 mm.

If your spring rate is correct, after you adjust the sag properly with you on the bike, check the free sag. (Sag without a rider) You should have 5-10 mm of free sag. If you have no free sag, your spring(s) are to soft. More than 10 mm of free sag, and your springs are to stiff.

Thanks guys.

I'm definitely gonna need a suspension "coach" this winter. You guys keep on writing , I'll keep on reading.
