Why? Once the fronts are unloaded, all the weight is at the rear and that's as good as it gets!
And, if the wheelie bars are carrying any part of the load, that means you're losing rear wheel loading and hurting your performance.
Assuming you're interested in bettering your 60 foot times...instead of winning wheelie contests..., you should be figuring out what you can do to shift weight forward and eliminate the need for wheelie bars.
