350x lost compression? Plz HELP!

[ChrisBigRed]

Alright I was recently having problems with my 350x, the bike would die down at full throttle. So I pulled out the carb. To try and see what was going on, I put the carb. Back in and go to start it but the kick start lever just feels way to easy to kick. And it wont start it sounds like it wants to but it won't. You can pretty much start it with your hand.. I just need to know what I'm dealing with and if any of you guys have had this problem?

see if your de compression cable is sticking with the valve open

you could have bent valves :(

Check the cable 1st, then check to make sure the kicker is turning the motor over . Then check the valve specs then. If then you dont have any compression. The compression tester should have a way for you to hook some compressed air to it..... put the bike at Top dead center and hook the air to it...... Listen for where the air is escaping and fix the problem from there dont shoot 150psi to it.... 80-100 is enough.
