I've read a few posts where people mention a "pogo-ing" effect on the older bikes after installing the 1000# spring.  How bad is it? Enough that I shouldn't upgrade the spring? Does it negatively affect handling/cornering? My bike has the flip and grind done to it, just FYI.

I already have a spring, I just haven't installed it yet. Thanks in advance.

   I put the 1,000# spring on my '02 when I installed the adjustable lowering links and I have never noticed any pogo-ing effect. It is stiffer, but that was the purpose, since I have the fender so close to the tire. As far as I can tell, the handling is still great. I guess the only reason for switching to it is to reduce the bottoming out, so if you aren't having that issue, there may not be any reason to change it though.

Yeah, I don't think you should intall it. I think you should give it to me instead

Seriously I thought the pogo-ing was something that could be assisted by adjustings the dampener. If the 02's have them?

Good luck

i put the 1000# on my '02, and it stopped the pogo effect i sometimes experienced when turns were bumpy.  it helped the handling in corners for me.  i'm a large guy, and i recommend it for larger riders, or if riding 2up often.  it was a very good mod for me. 

Troll has it right- On those stupid speed humps, I sometimes bottom out if I'm going fast enough (yes, I slow down for them) and I ride 2-up with my daughters sometime. Thanks, I'll be installing it soon.

2003+ bikes have both adjustable preload and rebound dampening.  My 2003 doesn't pogo with adjustable lowering links and Eibach 1,000 pound spring, and rebound adjusted all the way.

Your's is a 2002, so . . .  

Unless upgraded with '03+ shock, the 2002 bikes have a shock with adjustable preload, but not rebound dampening.  You might double-check those posts and see what year the guys had, I don't recall any members with 2003+ bikes complaining about pogo (?) and the guys with 2002 bikes didn't seem to be saying the 1k spring's pogo was any worse than the pogo had been with the stock spring (?).  I'm getting old hehe so double check me I'm probably wrong lol.

Mine's an '02. I should have posted that in the original question. I'll re-read what I read. :)

isnt it supposed to be damping not dampening

The POGO effect has always been associated with the later bikes, '03' & up and is created by an improper adjustment of the metering valve for the rebound damping

So your bike doesn't pogo 2-up, does it pogo when solo?

Weird.  My '03 rides great solo and 2-up. No Pogo.

I referred to individual posts like these when making my decision to go 1,000# Eibach.  

Not the whole topic, just the one specific post for each, as linked here:

 I'm sure there's others with the opposite view - I'm just saying its odd is all, since the addition of rebound dampening supposedly improved suspension performance significantly.  The only '02 I rode was a whole different animal re: rebound.

I know from practical experience that the 1000# Eibach works great with the '02' model using the PCS links and 2-up riding of average weights ....  The POGO effect has always been associated with the later bikes, '03' & up and is created by an improper adjustment of the metering valve for the rebound damping  

Dampening is to get wet, but its also defined as "to restrain".

Damping is cool physics lingo for reducing the magnitude of oscillations.  Hoity toity!

The Yami manual happens to use Damping - so you are more right that me hehe.

Many motorcycle and automotive suspension manuals use dampening (but I'm old).

Heck, I don't know which is more right I'm just a biker!

Perhaps, but so far you are the only one to rightly point out that it's about the quality of the damping circuits and not just a matter of a heavier spring.  One could replace the spring with a solid post and resolve wallowing too, but besides Jesse James and OCC, who would want to ride the damn thing?

I induce a bit of wallowing in mine from time to time, but it isn't enough to effect handling and given the type of bike it is I'm not going to spend any time worrying about it.  With a couple of gel seats under the leather seat cover, this bike has a nice firmly sprung but reasonably supple ride for all but the nastiest road distrubances.

I changed to the 1000lb spring and had a lot of pogo-ing  I adjusted the DAMPING (lol) and was surprised at how much of a difference just a couple of clicks could make
