To take the limiters out Carl-open up your rear shocks-obviously take the cap off and empty the oil out. Then remove the bottom from the shocks-the bit that threads onto the shock shaft. Take the shock shaft out and check you have no limiting washers fitted under the piston.
If you have-take them out.Then rebuild the shocks as normal. If you need even more droop-you can thread the shock ends back on but instead of tightening them all the way up-leave 2 threads showing.This should sort out your problem
