After 111,000 miles had a leaking front fork seal. Since I was having the dealer replace the seal decided to change the fork springs to the Progressive - to stop the "diving" with braking. Wish I hadn't. The "diving" is improved but not dramatically, but the bounciness of the front is waaay worse that with stock springs. I don't get vibration but every little wave in the road is transmitted up to the bike - as if it had no damping and every time the spring moves it immediately is transmitted to the frame. Suggestions?
Thanks
Gordon

What fork oil weight did they put back in? Seem to recall Progressive wants a heavier oil....

I used 15 wt oil and had no problems. Maybe I like firmer front ends. (ha) A few years later I went through the right fork again and used 10 wt, also with no problems.

I have had several sets of Progressives on different bikes over the years and never had a problem. It sounds like they may have not gotten the amount of fork fluid right. I have always used 10W oil.

Its been a while, but as I remember Progressive had in the instructions to use 1oz less oil than the book says. The Mechanic at the Honda dealer that did my forks would not adjust the amount, went by the book. Never had a problem. I also was told to have them put in upside down so they would make less noise. I guess that worked I don't think they make any noise.

Most of us like them, but some people prefer "Cadillac suspension" over "race car suspension"... "race car suspension" works hard to keep your wheel on the ground and transmit feedback to the driver... But still... maybe there's some issue... most of us like them... -Mike |

Sounds like the damper was not filled properly, prior to reassembly.
It's in the repair manual.

Jeff....who did you have do yours? Right before I went into the hospital, I had a left side fork leak. I'm thinking of possibly getting someone to put Progressives in mine sooner or later, but don't know who to turn to. It's more than I want to do myself. Was thinking to take it to Terry Smith on Racetrack Road, but dunno. |

I've done quite a few fork rebuilds and I've found if you put to much oil in them this is what you get... I put 1oz less then factory calls for and never had a problem...

TJ gives excellent advise. I had my IS done by a dealer (PS fork springs) shortly after I got it, and the front end was like a rock with very little give for over a year (think hard tail front end). I like a stiff sporty suspension, but this was near brutal to the point it felt like my hands would be thrown off the bars on bad bumps. I desperately wanted my old springs back, but came to conclude that the new fork oil (10wt) was just overfilled, probably by some small amount.
Anyone doing full fork maintenance, with or without progressive springs, would do well to underfill fork oil by an ounce or two (from what is called for in the manual).
