i think my dealer put to much oil in my bike,what is signs of motor damage due to to much oil please help????

 

How much have you ridden it with it over-filled? I had the same problem as did my brother. The bike ran bad with too much oil(sluggish) and much better after we drained it to the proper level. We had no damage. Make sure the motor is warmed up and then let it sit for about 5 minutes before you check the dip stick.
