Not sure if LRD still sells a pipe for the 250R but that would be my choice. There pipe is actually adjustable so you can adjust it for the type of riding you do. If not I have a friend that has the Duncan Hi Rev Pipe on his LT500 and it works great. Just don't buy the Duncan Kit the carb that comes with it is a pain in the ass to get adjusted. My friends still doesn't idle and they told him that was normal.johng212004 said:
