For a second opinion
www.racetech.com . Both sites are good, and would never knock Jer. or race tech. I've had great results with both. But, its interesting how if I enter the same info on both sites, I get 2 completely different answers. ie mxtech says go softer and race tech says firmer.
As an example the info I entered is:
2001 yz250f wieght 210, riding type enduro, intermediate skill level(race tech asked)
stock forks .44
Race tech says use .463
MXtech says use .43
stock shock 4.8 (per race tech) 5.0 (per MXtech)
race tech says use 5.3
Mxtech says use 4.7
I don't know what that means, just I find its best to talk to the tuner in person before you actually order. I'm glad they are up fopr a reference point.
