Hello. can not to switch 2,3,4 gear on 7-8 rpm. i have new stroker 2.2 without balance shaft and new clutch ACT. before stroker i did not have this problem . what is it????

 

clutch. set a better, higher engagement point with your master cylinder

 

but it was good with transmission before stroker. clutch as new

 

If the clutch is new you still need to adjust it. What wakeskater is a good idea try it out.

 

explain me how to do it please?????

 

Their is a rod with a nut on it behind the clutch . Loosen the nut and adjust the rod to raise or lower your clutch pedal. Go to jacks transmissions website it explains how to do it and test your clutch to see if its dragging or not.
