SUPERJETRUSS Posted September 26, 2009 Report Share Posted September 26, 2009 Hey guys im new here and was looking around this site and its badass more info here than I knew existed. I just picked up a 2000 banshee with a smoked crank for $200.00 off a friend who needed $$$, and was wondering what options are out there for these motors, I was looking at hotrods 4mil stroker cranks, but what is all involved in building a stroker. Who makes a good crank Hotrod, trinity, vito etc. And is there a difference in a 5mil long rod 4mil crank, and a 4mil crank, if that makes any sence lol. I got some money to spend on this but dont want to break the bank either. any info would be helpful Quote Link to comment Share on other sites More sharing options...
spurdy Posted September 26, 2009 Report Share Posted September 26, 2009 A long rod has a 5mm longer rod and reduces stress on the piston. You need 795 series piston with this. 4 mil stroke moves the pin for the connecting rod toward the outside of the counter balance weight 2mm for an increased stroke length of 4 mm. This will require the use of a spacer plate (not recommended) or porting for the correct port timings and stroker domes. Domes will run you about $80, porting can be anywhere from $200 to $550 or so depending on who you have do it. Porting for stock stroke or a larger stroke motor is going to be your best bang for the buck but should also be choosen with riding style and all other mods taken into consideration.

SP So with a long rod do I still need to run a spacer plate or do the 795 pistons take care of that? do I also need to port for the long rod, like I do for the 4 mill? sorry im new at this Quote Link to comment Share on other sites More sharing options...

SP THANKS FOR ALL THE INFO!!!!! OK I think I understand this lol, to run a 4mill long rod crank its basically the same as the 4 mill but it uses the long rods to reduce angle for more reliability, and to do this I still need to port for the 4 mill and use the 795 pistons for the long rods. Is there any performance gain using just a long rod crank compared to stock or is just for reliability. Quote Link to comment Share on other sites More sharing options...
spurdy Posted September 26, 2009 Report Share Posted September 26, 2009 Sounds like you got it. Yes, long rod nets no performance gains, just reliability. SP Quote Link to comment Share on other sites More sharing options...
