Way too much low speed rebound!!!

Post by bikeman2502001 » 08:45 am Mar 19 2020

I just bought a low hour 2003 KDX 220 And am starting to fiddle with the dampening settings for around here Im going to have to go through the shock anyway because the bumper has rotted off but my question is has anyone ever experienced even when backing out the rebound adjuster
all the way I still have way too much low speed rebound My other KDX's Didnt have enough and required revalving. it is a low hour bike so I am assuming the shock hasn't been messed with yet but then again it is a used bike and anything is possible.

Sounds like you need to rebuild or have it rebuilt. Then figure out what it needs. Hard to tune anything, shock, carb, etc. that isn’t working as designed to begin with.

besides taking the spring off and checking it while in a vise...


A shock made in the spring of 2002 (18 years ago) is not working perfectly...

no bumper, so maybe no one ever bothered to change the oil

shocks lose pressure over time

YEP! It is time for fresh oil and nitrogen (and a bumper)

Do all that, then try again.

Thanks for your reply Im going to disassemble the shock tomorrow then
ill know if someone else has been there before. Ive been riding for 40 years now and I have never come across this before almost seems like there is a blockage in the shock shaft or something like that. After I get it apart Ill post here on what I find in case it might help others

Take the spring off before disassembly and gas discharge.

Pull the shaft all the way down, then GENTLY turn the rebound adjuster all the way in. After I have rebuilt them, they stay locked in place. See if it does the same.
