First off, YOUR TIRES ARE DEATH TRAPS. Before you drive anywhere on those things, buy some new rubber. Tires have a life span of close to 6 years. After that, you are a blowout waiting for death. See THIS THREAD
for more information.
I would also get new belts for the same exact reason your tires are shot: TIME. As cheap as the belts are and as quick as they can be changed, it makes no sense to be riding on belts that old.
Last of all, look at this thread
. There are some VERY important documents that you need to read in that thread and another thread that is linked within that thread.
