How can i put my rear shock back together on my stomp 110cc pit bike?

Hi, personally i would bin them. sounds like they have lost all damping, hence the boucing you said about and probably because of this the springs have compressed too much to be of any use, because the moment the weight of the bike was taken off them, the springs were short enough to let the collet fall out! you would normally need a spring compressor tool for this job.
