250-500cc wr250 Engine Vibration

I went out for a ride today and ended up coming back early. The engine started vibrating . It did not matter if the clutch was engaged or not. I got the bike home and checked the flywheel. It was tight. I dropped the oil and nothing unusual. I also pulled the clutch cover off and found some side to side movement on the clutch basket. I am not sure if this is normal. Does anyone have any advise as what it could be. The bike has about 25 hours on it.

I am just wondering if it is the same thing though as that post. The TT post was about a four stroke and MotoX has a two stroke. Did you check your reed cage yet? You might want to pull that out and make sure they are all there.

The engine still has lots of power and starts with no problems. The engine runs normal except for the heavy vibration. I am going to pull the clutch basket off tonight and see if I can find anything.

Check the motor mounts. The lower ones would come loose every few rides on me and it would start to vibrate. Make sure all the exhaust mounts are tight too while you are at it.

It ended up being the engine mounts. Thanks for the help.

Red loc tight ! Gota run that on my 500 or it comes loose quick
