miss

Driving on the road at aprox 90 miles I hit something, stone, pice of metal, who knows what, I could hear the knock. I was lucky because less tan half a mile there was some repairs in the road and We had to stop, I felt the bike shaky no traction, It was that I had the tire completly wet of...

Has anyone else similar experience like I do have? When I try to go hard on throttle Iam getting miss fire gaps time to time. Not sure if spark plugs are behind this or any other fault. Bike has nearly 20k done. Any clue? Thanks for comments
