Saddle is currently set right back. will push it fwd and run a 50 stem instead of 70 (have a collection of Thomson Stems
Hope you mean run a 70 instead of a 50? if you're runnin an extra inch of travel in your forks you're losing about a degree off your head angle, pushing that front wheel further ahead of you and reducing the pressure on it. so either go for the longer stem (but that'll also quicken the steering, so you may "snap" into corners harder than you expect and increase the chances of washout) or get onto those bars more.
If you reckon you ride too far back into turns then maybe you don't have enough flex in your arms to lean the bike right over (very common problem: weight back = straighter arms = limited sideways movement), and rely on turning the bars instead. This'll also increase the chances of washout.
If you ride with anyone else regularly get them to session some turns with you and shoot a bit of video on a camera or phone. Amazing what that'll reveal for you.
hope this helps a bit, chris@cycleactive
