Ok my bike runs and goes great but when I put it in gear and go it makes a grinding noise what is my problem

 

You can start off by checking that you have oil in the hubs,plus change it if it's been a while. Best to jack it up with all tires off the ground and you can test the awd system.Both front tires should engage when in gear with awd activated.You should be able to track it down to one side or the other,plus who knows,may be a drive shaft making the noise or a bearing in the front housing.

 

Wellll thanks for the advis but all wheels Engage it's a grinding nois towards the back side I thought the chain was so loss it was dragging the plate.??"???

 

Then just check sprocket teeth for wear and chain slack. On the ground adjust the chain slack to about 3/8" slack in the middle of the chain. Have the rear wheels off the ground,turn the wheels and see if the chain loosens and tightens up after adjustment. If it does then it could have worn links and may need to be replaced.Plus while you're at check for axle play at the rear concentric housing. If there is play then may be time for new bearings and seals.
