Finally got about 400 miles on the sled and the weak 1000 that worried me last season has turned into an animal. Rode some moderately bumpy trails last night and it felt like someone was punching the bottom of my seat when going over bumps. So first thing i thought was take all the shit outta my trunk since its right under my ass but it didnt help. Any chance the track is slapping the tunnel protectors? Its not very loose by any means but its all i can think at this point. Anyone else experience this? By the looks of the weather ill have some time to figure it out!!!!
