My beast weighs too much to lift the front wheel on it's 36T sprocket (84 lbs plus my 160-ish), but if I take Harley59's bike out to start it up it can lift the front wheel with me on it with the 48T sprocket it has (when it has warmed up a little).
A bent seat post will help move your weight back, making it easier to lift the front end. Just make sure you adjust the front brake to grab a little more, or you may not have enough weight on it when you try braking and turning to keep it from sliding (been there, done that.. front wheel of the cruiser slid sideways on a low speed turn and dumped me once).
