i need help!!!!

I started riding my first four wheeler (250X) about 3 months ago and i had to get new suspension for it. Well, the suspension wound up being on back order and my quad didn't run for about 3 or 4 weeks. When it was running before it had tons of compression, but when i went outside to start it and ride with the new shocks it had hardly any compression and won't start. I am new at riding and don't know what to do. Can anyone help me?

Are you sure that its compression? Firts check the spart plug, make sure it's getting fuel, and make sure the air filter is clean. Also, just make sure the kill switch is in the on position. If all those appear good, it could be your rings are waring out, but you would of been aware of this before you put it away because the compression would be down and it would be burning oil.
