I just bought a 86 250r. It has an ESR pipe. I have not heard to much about this pipe. There are a feew people on this forum that have them. DO u think i should get a new pipe or will this be sufficent?
Oh ya it is bored one size over. I ahvnt looked actually but the guy said it was when he blew it up. It has reeds also abd a dg silencer that about it. Also shoud i get a K&n filter. If i do will i probaly need to the jetting? This is my first 2 stroke and i know when i put my filter on my 250x i didnt need to change it.

 

might want to call ESR and ask them about the pipe. I run a new style ESR drag pipe, and its an awesome pipe...decent low end, and killer mid and topend, sweet sweet pipe.
