No Limit Powersports Posted July 1, 2008 Report Share Posted July 1, 2008 4mm stroker cranks will give you more stroke hence more displacement. But to utilize the added stroke and make more power you will need to have the cylinder ported to compensate. Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted July 1, 2008 Report Share Posted July 1, 2008 It will make a stronger midrange. It gives the connecting rods more leverage. Like using a longer wrench or cheater bar on a stuck bolt. josh Quote Link to comment Share on other sites More sharing options...
gregrob Posted July 1, 2008 Report Share Posted July 1, 2008 More in the midrange especially and generally more power everywhere including peak numbers if you have good porting to go with it. Quote Link to comment Share on other sites More sharing options...
