Message: [QUOTE="2strokepower, post: 838961, member: 56622"] Can someone tell me what exactly porting a pilishing does to your engine and how its helps/upgrades the performance. Will it give more bottom end to a 2 stroke 125 and last Is it worth my money to post and polish a 92 rm125. (I am also putting a fatty fmf pipe with a power core silencer on it )If that makes a difference or not deling with the port and polish. I dont know much about dirt bikes yet im very new to the 2 strokes any help would be appreciated. Thanks [/QUOTE]
