Other things to thing about. Make sure there is a flat spot in the top of your axle, not too big, but not too small. Make sure that your CG isn't too far foreword.

I too have a Ultra Stick 40 and have had the same problems, but they are all easily corrected. I have had mine for about 2 years, and i love it to death. I have had some crashes and things to fix so if you need anything in the future, don't be bashful!!!
