Larry,

It looks like your RR corner weight is too light....take about 50-75 pounds off the LF to increase the RR without upsetting anything else.  If that doesn't work, try increasing your shock rebound in the LF to increase compression in the RR.  Just remember...if one corner isn't working right, go to the opposite cross-corner...take away from one, to add to the other....hope this helps...good luck
