I picked up a used Thumpstar last weekend off of craigslist. The guy I bought it from had only ridden it on pavement. It had never been in the dirt. http://i22.photobucket.com/albums/b323/Motocox/Thumpstar2.jpg http://i22.photobucket.com/albums/b323/Motocox/Thumpstar1.jpg The bad part is it I had only ridden it 5 or 10 minutes when the preload adjuster on the shock gave out. So now the thing has been sitting all week while I wait for a new shock to arrive. My next project is to build a track, we have some land and a tractor with a bucket on the front. I can't wait.
