Baja Dune 150 - rear bounces non stop
 

So I have been working on a baja dune 150 and it rode great. parked it for a while (blown starter) and finally got it fixed up again. However, going down the road the whole thing bounces like a rubber ball! Boing, Boing, Boing, Boing, etc. Very annoying - what happened? Granted - I got it in rough shape for $200, could the shocks have up and died? I am no lightweight - 6'5" 240lb so I could believe that I killed the shocks. Any other thoughts?
Oh and I wired in a sweet 20" LED light bar. :)

Thanks,
Joe

stock shocks aren't the best, but not horrible, and if the buggy sat outside that makes it worse, also depends on your tires also, u might have adjustable shocks, you can turn the preload to a softer setting.
also tire air pressure plays a role.

Definitely sat outside. Tires were low and I added air just before taking a spin. Tires are original - Lord knows how old they are! But they have decent tread. Maybe flat spotting in the cold?

flat spots will cause a improper ride.

Check to see if the axle is bent.

On that same line, check the tightness on you nuts for your hubs and wheels.
