Hey I just bought my first KX a week ago. I was able to find a sweet 2004 KX500 with the original back tire and bone stock. I am excited to find this site. I am a bigger guy 6' 5'' and about 300lbs so I have orderd stiffer shock and fork springs. I plan on running Amsoil thoughout, (I had great success with Amsoil in my snomobile). I need to get a paddle and get out. Any hints will be great. I plan on keeping the motor stock. I am not the guy that likes an out of control bike. I like having lots of power on tap, but for my size the 500 in stock form is great, and I can not see myself ever running out of power at the dunes. I am in the Salt Lake City area, so if any of you want to hit the sand let me know.
