Re: Ohlins shocks ... nightmare!

[Bob MacFarland <emoto1@xxxxxxxxxxx>]

Springs aren't all the expensive, and Ohlins are a major investment that 
are worth getting sorted out. My suggestion is to call a shop like Stig 
Pettersson. You can talk to them about your problem and send out your 
shock. They can measure the spring (http://www.ppsracing.com/serv02.htm) 
and let you know some options about what they can do for you.
