who are u guys???
2f4r is a waste...it cant runn that much better and is supposedly shittier casting... evo cil and pipe are nice too.....very nice.....added speed should have them because the mini gps they brought in come with kleihn 28mm d-slide carbs...i dunno if they are in at the moment but he should get them... arrache carbs a re shitty..i had a 19 and it ran like shit, the black edition racing 21mm dellortho carb ran way better(i was first to have one here)....big carbs are always beeter for full race cilinder...if u have a cast iron or any aluminum low reving to medium revving cil then the 19 is fine...
