Hi guys, I previously commented that I had a problem with my ninja, since I removed a piece of paper that obstructed a hole in the snorkel, the motorcycle made many explosions and i need to open more the throtle, I thought that the spark plugs could be dirty with oil, I changed the spark plugs and I put a K & N filter thinking that could be that problem, I put the piece of paper back to the snorkel and the motorcycle accelerated better, as before removing the piece of paper, the mechanic said that maybe the carburetors are not calibrated
