Understanding Sag
In order to let the suspension work properly, we allow some of the rear-wheel travel to be used when supporting the rider's weight, this is called 'sag'. The basic idea is to have around 10-20% of your bike's total travel as sag. This allows the rear wheel to drop into dips in the trail and maintain contact and traction.

Adjusting Sag on Rear Suspension
Changing the amount of sag in the rear suspension is done by increasing or decreasing the spring rate of the rear shock. The rear shock's body is threaded and you will notice there is a nut on one end of the spring. Turning the nut in the direction that compresses the spring will increase the spring rate and reduce the amount of sag. Turning the nut in the direction that expands the spring will decrease the spring rate and increase the amount of sag. Never turn the nut to the point where there is space between it and the spring, this may cause damage to the shock.

There is no "best" derailleur for any particular situation. Get one rated to handle the range, at a price you can afford, and that has good reviews. Performance is more affected by how well you set up derailleur and cables, as well as chain and condition of cassette, than by individual model differences.

Google "cannondale serial number". That is what anyone else would have to do to answer your question.

Did it occur to you to just Google "yellow jay miron hydramadic 20" trick bike"? Doing so pretty quickly shows that it is apparently a 1998 model.

It is very seldom possible to ID a bike by serial number alone, and you absolutely do not need to do so for replacement parts or repair procedures. Also, if there's no brand or model on the bike it has no significant value. Take to a bike shop or bike co-op for help.

Could be a number of things;
  • Cable is weather worn and jamed on the inside of its sleeve. Try a penertrating spray lobe or replace the cable.
  • The rear de-railer may be at fault, check if you can move it sideways with your hand just to see if it's free moving.
  • Twist grip may be damaged from bike being dropped on the ground, landing on it's side and handlebar. Remove/disconect the cable and see it the twist grip works smoothly.
  • The gears may be adjusted wrong. If they (handlebar bar gear selector) are in top gear but the derailer was pulled over to the lowest cog then that would give the same fault - not able to move your gear selector.

An owner's manual will not help you, and the procedure is the same as for any similarly equipped bike. It is the wheel you are removing not the tire, but you can then remove the tire/tube as well. Here is a video that should help, but note the comment below it about proper chain tension.
