alright, dropped in te new motor yesterday and its a screamer, makes my S5 look like a sport motor. i noticed though the bottoms of the c-hubs, where the mud guard connects to the bottom of the c-hub, is cracked on both sides. not sure if its from the mods i've done, ie. cut out the backs. so i threw in a set of aluminum cen c-hubs and with a little trimming they fit perfect, the hobao cvd's were rubbing on the c-hub a bit. i'll test it out today if it ever stops raining.
