01banch Posted February 13, 2010 Report Share Posted February 13, 2010 If your not all out drag racig I wouldnt go bigger than 35's. I might even consider some 33's or 34's. Quote Link to comment Share on other sites More sharing options...

jbooker82 Posted February 14, 2010 Report Share Posted February 14, 2010 I would go 35's on a cub and they are a desent drag port out of the box. If you building a dedicated drag bike then I would go 39's Quote Link to comment Share on other sites More sharing options...
