dufrain Posted March 13, 2009 Report Posted March 13, 2009 I am looking at some cylinders that were on a 404 and they are ported. I want to put them on a stock stroke motor with stock heads for now. I just have aftermarket reeds and fmf exhaust. They are also milled 1mm. Will they run ok being ported for the 404.Let me know what you guys think.thanx Quote
dajogejr Posted March 13, 2009 Report Posted March 13, 2009 I think you'll spend more time and effort getting those to work than getting a port done on your current cylinders. Quote
jbooker82 Posted March 14, 2009 Report Posted March 14, 2009 I though the 404 was a big bore stock stroke setup any way, not a 4 mill setup. Quote
dufrain Posted March 14, 2009 Author Report Posted March 14, 2009 Its a 68mm bore I think .I just figured it would take some more stroke to bring it up over 50cc. I think I will keep looking for some cylinders that are ported already.This banshee I just got looks like someone leaned it out and scuffed the piston until the rings are stuck,. Quote
vulvafan537240 Posted March 14, 2009 Report Posted March 14, 2009 I though the 404 was a big bore stock stroke setup any way, not a 4 mill setup. x2. a 68mm bore with a 4mm stroker is a 421. Quote
