Just got back from first long ride with new Springs in my 07 Midnight. Have Progressive on rear.
Wow what a difference! Bumps are a bit harder but man this handles like a new bike. No more dive and it's rock solid leaning into turns. Feels lie I'm on rails.
Left std 5 wt oil in forks. Glad I did ths is plenty stiff as is (I know that's what she said!)
Assume you installed std/non lowering springs ,correct?
Couple Questions,a few people here in RSC said they installed the std height progressive front springs and did in fact see a slight increase in ride height,was that the case for you?
And are you running the std height prog spring on stock yami
rear shock or are you running progressives std height 465 shock & spring setup?
I ask that because i went with prog std height rear spring and didnt get as good result as i expected/hoped for.
My bike had approx 12k miles on it when the std higher prog rear spring was installed and its very bouncy when adj in medium setting and that was accounting for the fact that springs slightly shorter then stock yami rear spring.
Me and the wife weigh approx 295-300lbs total and this bike would bounce 2-3x & bottom out too when going thru mild fairly shallow dips in road which in medium adj which it didnt do with sotock spring.
Thr stock shock/spring was having bottoming out issues even at full tight preload adj and bike not overloaded with 300lbs max with wife & myself on board.
So i adj spring preload to full /tight which improved it some reducing bouncyness esp when going thru slight dips but it still wasnt only bouncing 1x then stabilizong like it should .
Then when i adj rear srping tension to full tight spec (accounting for shorter pro spring) the ride hieght did go up noticably too which made bike feel more twitchy/almost like it was on a steel deck bridge at times .
So it was either leave rear sping adj there to calm down too bouncy /mushy thing back off spring tension and go back to boucy/boaty feel which i think is caused by the weak stock shock not dampening bike propelry putting too much load on spring maing it bouncy.
My feeling is that maybe the stock yami shock is toast even though i never overloaded the bike and the stock yami shock is simply not giving the dampening it should so when i had to adj spring load tighter to make up for weak shock bike hight increased makiing it bouncier then i feel it should be too.
Does that make sence to you guys?
I am going for the std ride height progressive 465 rear shock along with std height front fork springs to get rid the of horrible dive the bike takes when comming to a stop even when using minimal front brake pressure.
