You gota be fast. If you do it fast you may jump 100-300 RPM. It's bad for it, yes. Without a shifter with positive stops, it's real bad. I do it at least once everyday. It makes me feel better, tension just melts along with the tires. TRY IT, The REV limiter is there for a reason. To "KEEP" you from blowing it up so give it a try!
