You need special tools to remove the cartridges in Headshok forks.Mrwinkle said:Hi Guys and Gals I just purchased a used 2007 F3 in immaculate condition (or i thought) for $500. However i just found out that the fork doesn't lock out and shock bottomed out really easy. I took it to my LBS (Non Cdale certified) and he put 100lbs of air in the fork (i weight 230) and the fork works great far as suspension. However it still will not lock out. I read this thread http://forums.mtbr.com/showpost.php?p=1802943&postcount=4 and would like to know how to change the oil in the fork to see if this will fix the problem, before i have to send it off. Can someone please help me or lead me in the direction to the help thanks in advanced.
Your best bet is to send it off to get serviced, since you bought it used and don't know if that was ever done before.
Service should be cheaper than buying the tools to try to do it yourself.
send it to:
He has the reputation to be one of the best mechanics specialized in Lefties and Headshoks.
Sending it to cannondale is costly, takes really long to get back, and 9 times out of 10 they eff up.
