I'm very new to mx'in and have as my first bike a 2006 WR450 with all the "free" mod's and about $500 worth of other mods made to my bike (thanks to all the information I have pulled-off of this awesome web site). My question is this (and I'm sorry if this has already been asked, I couldn't find it) I watch people where I ride in the desert and they don't seem to have any trouble getting the front-end up, while in motion. I have tried gunning the throttle, popping the clutch, and all that happens is my back tire spins-out. Even at a dead stop on concrete, the back tire mostly spins! I have scooted my fanny as far back on the seat as I can and that helps a little. Any advice one of you experianced rider's could give a "rookie" would be greatly appreciated.
