Here is what I do. Turn your pre-load adjusters all the way in. This forces the fork spring to coil creating denser weight lower in the fork tube. Strap the front end hard. Full coolant over flow as high as it will alow. Add three gals of fuel or less depends on the wheelies along with a totally flat, horizontal to the ground swing-arm and start with 20lbs in the rear tire for your first few passes then less.. The horizontal swingarm does two things, it takes the up hill pull off the front sprocket and secondly gives you a little more control over the chassis. Take all the compression out of your rear shock and add enough re-bound so after compressing the tail rises up slowly, not bouncey, more power the faster it should move. Still learning...also get your center of gravity to the deck as close as rules allow.
