been there done that. Have you changed to lighter springs or anything like that? I ask only because you said you were total advance by 2800,not 3600. You usually dont run v.advance when you come into total that early(2800),and you usually have gone to atleast 1 lighter spring,to bring it all in that quickly. I would do what Stumpy suggets,then bump it up 2* at a time and see what she does. Good luck,keep us posted!
