SAVAGE420 Posted December 5, 2009 Report Share Posted December 5, 2009 358cc + +4mil stroke = 384cc Quote Link to comment Share on other sites More sharing options...
bbcmudtruck Posted December 5, 2009 Report Share Posted December 5, 2009 If you don't have a port job already, then have your cylinders ported with a mx/trail port and 4mil crank. Bump up your compression and timing. Don't forget to try a -1 or -2 swinger!! Quote Link to comment Share on other sites More sharing options...
banshee mx 19 Posted December 5, 2009 Author Report Share Posted December 5, 2009 ya its ported im thinkin of gettin a -1 swinger Quote Link to comment Share on other sites More sharing options...
Wildcardracing Posted December 5, 2009 Report Share Posted December 5, 2009 ya its ported im thinkin of gettin a -1 swinger Depending on what your transfer duration is right now, you may not be able to go to a 4mil. If the current porting is mild you might be ok. Quote Link to comment Share on other sites More sharing options...
TwistedSheeRida Posted December 5, 2009 Report Share Posted December 5, 2009 the 4 mill is def worth the price doing mine right now. I also have a -1 swingarm im putting on. like already said if your porting is to extensive you might be fd. Im .060 over puts me at 391 Quote Link to comment Share on other sites More sharing options...

jbooker82 Posted December 13, 2009 Report Share Posted December 13, 2009 when i get the 4 mill i want to get some vitos 404 cylinders and pistons and get them ported for trails onilly problem with that is $$$$$ That and the vito's cylinders probably come with port timings out of the box that are at least a dune port if not close to a drag port.I would check into it before you buy them.
