Hi

If you find the need to quick shift you can try clutch less shifting which is what 2 stroke racers do.

While you have the throttle open, in gear and driving, put slight pressure on the gear shift lever. As you reach the desired rpm momentarily shut the throttle, snick the next gear up and open the throttle. No clutch required and about as smooth as you can hope for.
THIS OPERATION IS NOT FOR DOWN SHIFTING, you must still use the clutch when going down the 'box say from 4 > 3, or 3>2 and so on....
